The 981 Pressure Transmitter is used to measure low pressures in a variety of mediums. This type of pressure transmitter aids in the measurement of overpressure, vacuum, as well as differential pressure in liquid and gaseous media. The pressure is measured as a differential from atmospheric pressure. The ambient temperature of the transmitter varies from minus 20 degree celsius to plus 85 degree celsius. Depending on the material of the pressure connection and diaphragm, media temperatures can reach up to 85 degree celsius.
