Description
Pressure measuring transducer
PREMASGARD® SHD/SHD-SD LCD
The PREMASGARD® SHD pressure sensor is used to measure relative pressures (max. 0...40 bar) in gaseous and liquid media. The pressure measuring cell is welded to the pressure sensor without any seals.
The SHD-xx-LCD device variant is supplied with an LCD-SHD display module. It is mounted below the angle connector. The module can be mechanically rotated and tilted, and the display content can be rotated in 90° increments to achieve the ideal reading position. The display types and pressure unit are configured directly on the display (menu-driven via buttons).

The pressure transducer converts the measured variable into a standard signal of 0 - 10 V or 4...20 mA. The process connection is G ½ . This pressure transmitter is used in hydraulics, pneumatics, process technology, mechanical and plant engineering.
