PAS Pressure Transmitter
Brand: KOBOLD Instruments, Inc
The Kobold Pressure Transmitter model PAS is a micro processor-based high performance transmitter, which has a flexible pressure calibration and a flexible output signal.
It has an automatic compensation of ambient temperature and process variables. A communication with the instrument and a configuration of various parameters is possible via the HART protocol. All data of sensor is to be input, modified and stored in an EEPROM.
