HMP4 Humidity and Temperature Probe for High Pressures, Modbus, 0.8%RH accuracy

HMP4 Humidity and Temperature probe is designed for applications that involve high pressures, such as compressed air systems and pressurized industrial processes. The operational pressure is up to 100 bars and operating temperature range -40..+180 °C (-40..+356 °F)

The HMP4 can be used as stand-alone Modbus RTU digital transmitter, or used together with INDIGO201 analog signal transmitterr or INDIGO202 Modbus RTU digital transmitter. The length of the high-temperature tolerant probe cable is two meters. The probe can be connected directly to the INDIGO transmitter or with a M12/5M extension cable up to 30 m

The probe is equipped with HUMICAPR2 composite sensor. Sensor purge functionality improves measurement performance under applications where the probe is exposed to high chemical concentrations

Each probe is individually pressure tested. Process connection is M22x1.5 or NPT1/2""

Included in the package:

  • HMP4 Humidity and Temperature probe
  • M22x1.5 and NPT1/2"" process fittings
  • Traceable 5-point calibration report
  • Mounting clips
  • Calibration adapter for HMK15 calibrator
  • Quick guide

Not included in the package:

  • IINDIGO201 or INDIGO202 transmitter, to be purchased separately
  • M12/5 extension cable
