S+S Regeltechnik PREMASGARD SHD, Operating Instructions Manual

Page: 7 / 16

The pressure measuring transducer PREMASGARD
®
SHD-LC measures relative pressures in the bar range.
It converts the measurand pressure into standard signals of 0 -10 V or 4...20 mA. Process connection is G ½ " straight external pipe thread.
SHD-LC is used for pressure measurement in gaseous and liquid media. Applications of this pressure transmitter are in hydraulics,
pneumatics, process technology, in mechanical and plant engineering.
Not applicable for ammonia and Freon!
