Differential pressure transmitter
Type: PAS
The KOBOLD pressure transmitter type PAS is a high performance microprocessor based transmitter with flexible pressure calibration and flexible output. It features automatic compensation of ambient temperature and process variables.
By means of the HART® protocol it is possible to communicate with the device and to perform a configuration of various parameters. All data of the sensor are read into an EEPROM, modified and stored.

Details
Applications
The pressure transmitter type PAS is available as piezoresistive pressure sensor and measures gauge pressure as well as absolute pressure. The sensor module converts the resistance into a digital value. The microprocessor control unit calculates the process pressure based on this digital value.
