The Valcom T7IM series includes SMART electronic Transmitters with 4-20 mA output and HART digital communication protocol available with piezoresistive (P series) or Ceramic (C series) Sensor. Piezoresistive sensor are based on silicon chip resistive Wheatstone bridge while ceramic sensors are thick film Sensors based on strain gauge principle with backplate and diaphragm in ceramic material; in both versions the sensors are calibrated individually together with their own seal.
Configurations and adjustments can be made locally, by means of push buttons and display, or remotely using HART communication protocol.
