HMP8 Adjustable insertion Process Humidity and Temperature Probe 40 bar/180°C, Modbus, 0.8%RH accuracy

HMP8 Humidity and Temperature probe is designed for pressurized applications up to 40 bars, where adjustable installation depth and possibility to remove or insert the probe in the pressurized process is required. The design of the probe head is pressure and vapor proof and suitable for continuous temperatures in -40..+180 °C (-40..+356 °F). The sliding metal-to-metal seal at the process fitting allows adjustable installation depth between 41..149 mm

The HMP8 can be used as stand-alone Modbus RTU digital transmitter, or used together with INDIGO200 series of transmitters. The high-temperature tolerant cable in the probe is 2 meters. The probe can be connected directly to the Indigo201 or with M12/5M extension cables 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 ISO1/2"" or NPT1/2""
