The PR41XEi series are designed for measuring very low pressure values in the mBar or µBar ranges in hazardous areas. The Series 41XEi 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.
