The CS408 is a submersible pressure transducer manufactured by Pressure Systems to measure surface water, ground water, or hostile fluid levels. Each transducer is individually calibrated, and ships with a calibration sheet. The sheet specifies I/O conditions, as well as actual data reflecting the unit’s static accuracy and thermal characteristics. A vent tube, which runs the entire length of the cable, vents to the atmosphere so the measurements do not have to be corrected for barometric pressure. | |

The CS420 submersible pressure transducer is manufactured by Druck for use in surface, ground water, or hostile fluid applications. Changes in water level correspond to pressure changes on a strain gage bonded to a pressure-sensitive diaphragm. When a precision excitation voltage is applied, the electrical resistance varies with changing liquid pressure. Our dataloggers supply the excitation voltage and measure resistance, then convert the measured value to the desired units (i.e., pressure, depth, or level). | |

The CS431, manufactured by Instrumentation Northwest for use with Campbell Scientific dataloggers, measures both water level and water temperature. It uses piezoresistive strain gage technology to measure water level and an on-board thermistor to measure water temperature. The CS431 has a 316 stainless steel body and Viton® and Teflon® wire seals that resist corrosion. Its double-sealed, cable harness protects the cable jacket and reduces the possibility of leakage. The end cone is interchangeable with an NPT inlet. | |

The CS440 submersible pressure transducer is manufactured by ACData Solutions, Inc., to provide liquid level measurements in wells, lakes, streams, and tanks. The pressure transducer uses an isolated silicon strain gauge sensor housed in a 316 Stainless Steel package. The rugged, polyurethane cable jacket remains flexible under harsh conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. The vent tube terminates inside a desiccated chamber to prevent moisture from entering the system. | |
