CS440-L ACData Sol'ns SPXD-500 4-20 mA Pressure Transducer


The CS440 submersible pressure transducer output a 4-20 mA signal to indicate observed pressure level. The CURS100 was typically used to convert the 4-20 mA signal to a millivolt signal. The datalogger then converted the millivolt signal to user-selected units (such as psi or feet). The static accuracy was ±0.1% over a 0° to 50°C temperature range.

Datalogger Considerations

The CS440 is measured with a single-ended datalogger instruction after converting the sensor signal from milliamps to millivolts using a 100 Ohm resistor.
