Model 853 6,000 PSI Pressure Switch

The model 853 is a 0 to 6000 PSI adjustable pressure switch designed for either pneumatic or liquid service. The model 853-1 is the same as the 853 except it employs a temperature compensating element. Its primary purpose is to permit filling natural gas cylinders on a cold day without the danger of the cylinders becoming overpressurized if moved to a warm area. Consequently the set pressure of the 853-1 decreases with temperature.


Maximum pressure 6000 PSI (40 MPa)
Electrical rating 5 amps, 250 V AC, UL & GSA lsted
Switch SPDT (NO & NC )
Operating temperature range -50F to 160F
Pressure connection 1/4- male NPT
Electrical end connection 1/2" male NPT
Size 7/8" hex by 3.1'' long
Materials body - anodized alum. internals - brass, Stainless. Viton seals
Temperature compensation
        model 853     none
        model 853-1  9 PSI/F (0.11 mPaiK)


The 853 pressure switch is a simple, compact unit that offers exceptional accuracies. It is trouble free and requires no routine maintenance. The temperature compensated version (model 853-1) can be supplied with different temperature sensitivities on special order. As normally supplied, the 853-1 approximates the pressure variation with temperature of compressed natural gas. The purpose being to prevent overfilling of cylinders in a cold environment.


• Compressor shut off control
• Process industry control
