Description
The liquid-lled model 213.53 mechanical Bourdon tube
pressure gauge is constructed with a case from stainless
steel and wetted parts from copper alloy.
WIKA manufactures and qualies the pressure gauge in
accordance with the standards EN 837-1 and ASME B40.100.
As a safety function, this instrument has a blow-out device. In
the event of a failure, overpressure can escape there.
Due to the case lling, the pressure element and movement
are eciently damped. Therefore, these instruments are
particularly suited to measuring locations with high dynamic
loads, such as fast load cycles or vibrations.
The cases of the model 213.53 are available in nominal
sizes of 50 [2"], 63 [2 ½"] and 100 [4"] and full IP65 ingress
protection. With an accuracy of up to class 1.0, this pressure
gauge is suitable for a wide range of applications in industry.
For mounting in control panels, the pressure gauges with a
back mount process connection can be tted with a mounting
ange or with a triangular prole ring and mounting bracket.
