說明
The liquid-filled 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 qualifies 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 filling, the pressure element and movement are efficiently 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 fulfil 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 fitted with a mounting flange or with a triangular profile ring and mounting bracket.
