PR41 Low Range Relative Pressure Sensor

PR41X Low Range Pressure Transmitter.

The PR41X series are designed for measuring very low pressure values in the mBar or µBar ranges. The Series 41X capacitive pressure transmitter from Keller combines a ceramic measurement cell for low pressure ranges with the µP electronics of the digital series 30 transmitter. The pressure values from the signals of the pressure and temperature sensors are determined by polynomial compensation. The values can be displayed and stored on a PC via an RS485 interface and programming can also be carried out. Analogue outputs are scaleable within the sensors range using the CC30 software and options are available for 4-20mA or 0-10V.

    With the CCS30 software and the relevant K114 converter, the calculated pressure can be displayed on a computer. The CCS30 software also allows the recording and graphic display of pressure signals on a PC, adjustments of the zero point, rescaling the analogue output range and call up information on the unis pressure, temperature ranges and serial numbers. Up to 128 transmitters can be hooked together to a Modbus or Keller Bus protocols systems.
