Cynergy3 Float SwitchThe Cynergy3 SSF24 series float switch is a vertical mount type and has NO/NC output This float switch has a stainless steel 316 body. It has a maximum operating pressure of 10bar. The switch is mounting on the top or the bottom of the tank from the inside. Hence， it requires access to the inside of the tank. The switch action may be reversed by removing the float， inverting it and then refitting it to the stem. What is a float switch? An SSF24X100 switch is the type of level sensor， a gadget to recognize the level of fluid inside a tank. The switch might be utilized to control a pump， as a pointer， a caution， or to control different gadgets. It consists of a reed switch and a pivoted magnet and can be used for normally open (N/O) or normally closed (N/C) operation. The switch action can be reversed rotating the switch through 180°. Guide how to choose the correct float switch One of the most reliable， well-demonstrated technologies for fluid level detecting is float switch. This sort of switch involves a magnet contained inside the float and also an attractive reed switch contained inside a settled housing. The movement of the float， due to changing fluid level， will cause the reed change to work (for instance close or open) at a specific level. This trusted and tried technology depends on a generally straightforward plan that offers long haul quality without the requirement for the client to calibrate a switch. There are different methods available on how to choose a float switch for a particular application， here are the main factors to consider: Physical arrangement and style The choice of styles depends on the physical arrangement of the tank， availability of mounting positions and whether there is access inside of the tank. Fundamental styles are horizontal / side mounting and vertical mounting. Horizontal / side mounting has a fixed housing， which you can find on the wall of a tank and it has got a hinged float attached to the fixed housing. Vertical usually have a fixed vertical stem and that is installed at the top or bottom of the tank. Material selection It is very important to choose a float switch that is made from the right materials， which are compatible with the liquids and temperatures of the chosen application. While using incorrect material it can resolve in damaging the component as well as the failure of a float switch. Material types: Nylon ? used for oils， diesel， organic chemicals and MEK (methylethylketon) based printing inks Polypropylene (PP) ? acids and alkali， detergents， oils， water， organic chemicals Polyphenylene sulphide (PPS) ? used for more aggressive chemicals and higher temperatures， up to 120℃ Stainless steel ? medical and food industries， hydraulic fluids， chemicals and environments with high-temperatures up to 135℃ Buna/Nitrophyl ? diesel， oil， petrol and water (stationary applications) D300 foam (PVC) ? mostly for hydraulic oils and chemical solutions Electrical You need to fully understand what is the nature of the load that requires to be switched and make sure that the float switch is adequate for holding your load. The electrical ratings， which we provide in specifications are resistive loads. Cables In areas where harsh liquids may spill onto external wiring， it is important to underline particular materials for the cables in connection to the float switches. You can either use standard， UL-approved cable types for the range of float switches， as well as high-temperature， low smoke zero halogen (LSZL) and other specialised materials.Features and BenefitsMinimum fluid SG is 0.8 Maximum switching power 50VA Cable length is standard 100cm Mounting thread is 1/8in BSP Cable size is 17/0.10 - AWG22 Maximum operating temperature is 120℃ Float SG 0.7 Lead outs are 100cm XLPE 17/0.1CertificationsISO9001

Description。The SparkFun RTK Express is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， logging， and all types of post processing， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Express can also be used as a base station. With the press of a button， two RTK Expresses can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Express with their choice of GIS application on a phone or tablet. The built in battery allows for over five hours of field use and is compatible with common USB battery banks.。We took all the lessons from the RTK Surveyor and built the RTK Express. The RTK Express is built upon the same ZED-F9P u-blox receiver as the original RTK Surveyor so you can expect the same incredible performance and rich feature set. The embedded display allows for immediate feedback of horizontal positional accuracy， satellites in view， logging status， survey-in status， battery level， Bluetooth(R)MAC， etc. The rocker switches found on the original have been replaced by keypad buttons. We increased the battery to 1300mAh for a longer run time. The internal switches have been replaced by a digital Mux allowing for some really exciting applications including event triangulation. More ESD protection was added to protect the RF path， and we even threw in an accelerometer for digital leveling in the field.。This device can be used in four modes：GNSS Positioning(～30cm accuracy)。GNSS Positioning with RTK(1.4cm accuracy)。GNSS Base Station。GNSS Base Station NTRIP Server。In Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.。In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a second RTK Surveyor/Express setup as a base station.。In Base Station mode the device is mounted to a temporary position(like a tripod)and begins transmitting correction data over a radio or Internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy. The RTK Surveyor and RTK Express are interchangeable as a Base Station； an RTK Surveyor can be a base for an RTK Express and vice versa.。In Base Station NTRIP Server mode the device is mounted to a semi or permanently fixed position(like a roof)and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or Internet connection. This type of base is a very easy way to set up a very precise absolute correction source.。Two cables are provided with the RTK Express allowing a user to plug in our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).。Note：The SparkFun RTK Express is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces. These items will need to be purchased separately from the Hookup Accessories below.。Get Started With the SparkFun RTK Express Guide。Features。GNSS Receiver：ZED-F9P。Concurrent reception of GPS， GLONASS， Galileo and BeiDou。Receives both L1C/A and L2C bands。Current：68mA - 130mA(varies with constellations and tracking state)。Time to First Fix：25s(cold)， 2s(hot)。Max Navigation Rate：PVT(basic location over UBX binary protocol)- 25Hz。RTK - 20Hz。Raw - 25Hz。Horizontal Position Accuracy：2.5m without RTK。0.010m with RTK。Max Altitude：50km(31 miles)。Max Velocity：500m/s(1118mph)。Bluetooth(R)Transceiver：ESP32 WROOM。Xtensa(R)dual-core 32-bit LX6 microprocessor。Up to 240MHz clock frequency。4MB of flash storage。520kB internal SRAM。Integrated 802.11 BGN WiFi transceiver。Integrated dual-mode Bluetooth(R)(classic and BLE)。Hardware accelerated encryption(AES， SHA2， ECC， RSA-4096)。2.5 μA deep sleep current。Overall Device。Internal Battery：LiPo 1300mAh with 500mA charging。Radio Port：3.3V TTL Serial(57600bps RTCM TX/RX)。Data Port：3.3V TTL Serial(115200bps NMEA)。Embedded OLED Display for available satellites， data logging， and more.。Push button controls。Weight：162g(entire device including battery)。Dimensions：132mm×101mm×32mm(5.2in×3.9in×1.2in)。1x Qwiic Connector。Changes：This version(which replaces SPX-18019)uses a reinforced edge mount SMA connector for better resiliency when a fixed 'stub' antenna is used.

If enabled in automotive applications， the internal IMU augments the position information when GNSS reception is degraded.。In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a RTK Surveyor/Express setup as a base station. If enabled in automotive applications， the internal IMU augments the position information when GNSS reception is degraded.。Two cables are provided with the RTK Express Plus allowing a user to plug in our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).。Note：The SparkFun RTK Express Plus is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces. These items will need to be purchased separately from the Hookup Accessories below.。Get Started With the SparkFun RTK Express Guide。Features。GNSS Receiver：ZED-F9R。Concurrent reception of GPS， GLONASS， Galileo and BeiDou。Receives both L1C/A and L2C bands。Built-in IMU(triple axis accel， triple axis gyro)。Current：68mA - 130mA(varies with constellations and tracking state)。Time to First Fix：25s(cold)， 2s(hot)。Max Navigation Rate：PVT(basic location over UBX binary protocol)- 25Hz。RTK - 20Hz。Raw - 25Hz。Horizontal Position Accuracy：2.5m without RTK。0.010m with RTK。Max Altitude：50km(31 miles)。Max Velocity：500m/s(1118mph)。Bluetooth(R)Transceiver：ESP32 WROOM。Xtensa(R)dual-core 32-bit LX6 microprocessor。Up to 240MHz clock frequency。16MB of flash storage。520kB internal SRAM。Integrated 802.11 BGN WiFi transceiver。Integrated dual-mode Bluetooth(R)(classic and BLE)。Hardware accelerated encryption(AES， SHA2， ECC， RSA-4096)。2.5 μA deep sleep current。Overall Device。Internal Battery：LiPo 1300mAh with 500mA charging。Radio Port：3.3V TTL Serial(57600bps RTCM TX/RX)。Data Port：3.3V TTL Serial(460800bps NMEA)。Embedded OLED Display for available satellites， data logging， and more.。Push button controls。Weight：162g(entire device including battery)。Dimensions：132mm×101mm×32mm(5.2in×3.9in×1.2in)。1x Qwiic Connector。1x microSD Socket for optional logging
