Description
Pressure measuring transducer
PREMASGARD® SHD/SHD-SD
The PREMASGARD® SHD-SD pressure transmitter measures relative pressures in the bar range. It converts the measurand into a standard signal of 0-10 V or 4...20 mA. Process connection is G ½" straight external pipe thread.
The SHD-LC measuring transducer is used for pressure measuring in gaseous and liquid media. Applications are found in hydraulics and pneumatics, in process, mechanical and plant engineering.
Not suitable for ammonia and freon!
