Electrical contact pressure gauge
with aluminium case

Type: P531, P532, P533, P534,P537, P539

 

Service intended

 

P530 series are designed for a local reading of measured pressure and equipped with the inductive contact block which allows all the combinations of contacts to be used. The contact block is mounted on the dial. The window is fitted with a knob for external adjustment of the setpoints.
