Description
Pressure measuring transducer
PREMASGARD® SHD/SHD-SD
The PREMASGARD® SHD ressure 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 device is used for pressure measuring in gaseous and liquid media. Applications can be found in hydraulics and pneumatics, in process, mechanical and plant engineering. The pressure measuring cell is gasketless welded together with the pressure transducer.
