The model 853 pressure switch 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. It's primary purpose is to permit filling natural gas cylinders on a cold day without the danger of the cylinders becoming over pressurized if moved to a warm area. Consequently the set pressure of the 853-1 decreases with temperature.
Features:
- Pressure Switch
- Temperature Compensating -13 psi/degree °F
Installation
Use a suitable pipe thread sealant such as Teflon tape on inlet threads. Avoid over torquing pipe thread. Normal torque applied with a 6 or 8 inch long wrench is ample. Use ample teflon tape - 3 or 4 turns, not 1 or 2 turns. The switch is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.
