PREMASGARD SHD - LC
The pressure measuring transducer PREMASGARD
pressure into standard signals of 0 -10 V or 4...20 mA. Process connection is G 1 ⁄ 2" straight external pipe thread. PREMASGARD
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 !
