Model P1547/P1548/P1549/P1550

with Capsule Element ND 50 and ND 63

Pressure Gauge Model P1547 P1549

The pressure gauges with capsule element are used to measure small positive / negative overpressures in gaseous media. The capsule element system consists of two capsule element halves soldered together. When subjected to pressure, the capsule element moves a predetermined distance. This travel is converted by a movement into the rotary motion of the pointer.

The gauges can be supplied with cover ring, triangular front ring or mounting flange and panel mounting clamp as required for the installation conditions. The casings are available in steel black finish, steel or stainless steel.
