The CS400 submersible pressure transducer, manufactured by Pressure Systems, was retired in January 2009. It measured surface water, ground water, or hostile fluid levels with a static accuracy of ±0.25% FSO. A related probe, the CS405, offered a static accuracy of ±0.1% FSO. The CS400 required a 7977 resistor assembly to connect it with our dataloggers.
The "-L" on a product model indicates that the cable length is specified at the time of order.
CS400-L Compatibility Information
The probe requires two differential channels and one switched excitation output. Completing the sensor's circuit at the datalogger requires the 7977 resistor assembly. The CS400 is also compatible with our PST3/8 Pump Slug system (retired).
