Pressure Measurement for HVAC & Chillers
Industrial screw chillers, VRF heat pumps, refrigerant loops & clean air ducts
Why Standard Catalog Sensors Often Fail in this Application
Refrigeration lines experience phase transitions between gas and liquid, low suction pressures, and aggressive fluorinated or ammonia refrigerants with POE oils.
What to Specify When Ordering for this Process
- All-welded SS316L wetted sensor (zero internal O-rings) to prevent gas permeation
- Built-in internal pulse snubber to prevent damage from liquid slugging
- 7/16-20 UNF female Schrader fitting for direct service valve mounting
- IP67 environmentally sealed electrical cable termination
Always specify an internal snubber when mounting near the compressor discharge port where valve flutter can produce high-frequency micro-spikes.
