Model 853 6,000 PSI Pressure Switch GENERAL INFORMATION 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. SPECIFICATIONS 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) FEATURES 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. TYPICAL APPLICATIONS • Compressor shut off control • Process industry control • Gas or hydraulic over-pressure shut off • Test panel shut off and control • Filling compressed natural gas (CNG) cylinders for mobile equipment
