Diaphragm Pressure Gauges for chlorine metering services vertical diaphragm, polyamide screw ring case

Information on advantages, application fields, temperature resistance, metrological features and pressure ranges of all available diaphragm pressure gauges with vertical diaphragm can be found in our model overview 4000.

Application

Diaphragm pressure gauges with vertical diaphragm model PsPK 63-2 have been developed for the application in chlorine metering services. The lower part of the diaphragm with the connection thread is made of steel. The wetted parts are not enamelled. The diaphragm is protected by a fine silver foil which is applicable for use under vacuum. The case made of impact resistant polyamide with screw ring protects the inner parts from all external harmful influences (chloric gas).

Nominal Case Size (NCS) 

63 (mm) (2 ½”)

Accuracy (EN 837-3)

Class 2.5

Pressure Ranges (EN 837-3) 

0 – 1 bar to 0 – 40 bar (0 – 15 psi to 0 – 600 psi)

also all corresponding standard vacuum and compound ranges;

preferably -1 – 0 bar and 0 – 16 bar (-15 – 0 psi and 0 – 200 psi)

Maximum Load Limits

Steady load: full scale value

Dynamic load: 90 % of full scale value

Overload: 1.3 x full scale value

Temperature Resistance

Storage temperature: -40 °C to +70 °C ( -40 °F to 158 °F)

Ambient temperature: -20 °C to +60 °C ( -4 °F to 140 °F)

Medium temperature: +60 °C max (140 °F)

Reference Temperature

 +20 °C (+68 °F)

Temperature Caused Error 

If the operating temperatures of the measuring unit (resilient element and movement) deviate from the reference temperature, additional deviations of the indication could occur. In accordance with EN 837-3 these can be up to ± 0.8% of the span per 10 K.
