APPLICATION GUIDE // COMPRESSED AIR & GAS

Pressure Measurement for Compressors

Rotary screw compressors, piston compressors, centrifugal packages & air receivers

THE OPERATING CHALLENGE

Why Standard Catalog Sensors Often Fail in this Application

Compressor discharge lines subject transmitters to continuous mechanical vibration, oily air media, discharge temperatures up to 100°C, and millions of load/unload cycles.

PROCESS PARAMETER PROFILEENGINEERING BASELINE
Typical Working Range:0–10 / 16 / 25 bar (Air discharge), 0–6 / 10 bar (Oil circuit)
Process Media:Compressed air, synthetic compressor lubricant oils
Fluid & Ambient Temp:-20°C to +100°C
Primary Failure Risk:Continuous pulsation vibration fatigue and oil mist fouling
ENGINEERING SELECTION CHECKLIST

What to Specify When Ordering for this Process

  • Specify SS316L wetted materials compatible with synthetic polyolester / diester oils
  • Select DIN 43650-A connector with IP65 rating for robust oil/dust exclusion
  • Ensure 2x overload rating to handle sudden unload pressure surges
  • Pair with inline dew point transmitters (S220) downstream of dryers
ACT FIELD INSTALLATION ADVICE

For rotary screw compressor packages, mounting the pressure transmitter after the oil separator block prevents heavy direct thermal shock from uncooled raw air.
