Vaisala HMP8 Relative Humidity and Temperature Probe for Pressurized Processes and Adjustable Depth and Pressure 40 Bar 18-30 VDC IP66

Vaisala HUMICAP® Humidity and Temperature Probe HMP8 is designed for pressurized applications in compressed air systems, refrigerant dryers, and other pressurized industrial applications where easy insertion and removal of the probe and adjustable installation depth into the pipeline are needed. The HMP8 is part of the Indigo product family and compatible with Indigo500, Indigo300 and Indigo200 series transmitters and free Insight PC Software.

Features:

• RH accuracy up to 0.8 %RH, Temperature accuracy up to 0.1 °C (0.18 °F)
• Temperature measurement range -70 ... +180 °C (-94 ... +356 °F)
• Sensor purge provides superior chemical resistance
• Probe installation depth can be freely adjusted and probe can be hot-swapped from pressurized pipelines with an installation valve
• Modbus RTU over RS-485
• Plug & play compatible with Indigo™ series of transmitters
• Traceable calibration certificate: 5 points for humidity, 1 point for temperature

Proven Vaisala HUMICAP performance

Vaisala is the original innovator of the thin-film capacitive humidity measurement technology, which has now become the industry standard in humidity measurement.

Chemical purge minimizes effects of contaminants

In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals.

Flexible connectivity

The probe is plug and play compatible with Vaisala Indigo series transmitters, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.

Vaisala HMP8 HUMICAP® Humidity and Temperature Probe is designed for demanding industrial applications where high accuracy and stable measurements are essential. It's leak-tight threaded process connection has an adjustable insertion depth and can withstand high pressure or vacuum environments up to 40 bara. The operating temperature range is -40 ... +180 °C (-40 ... +356 °F).

This probe can function as a standalone instrument with Modbus RTU communication, otherwise it is compatible with the Indigo Transmitters if analog outputs, relays, or a display are needed. In addition to relative humidity and temperature, this probe provides values for a number of other  calculated parameters such as ppm, absolute humidity, dew point, enthalpy, mixing ratio, wet bulb (all available in both metric (°C) and non-metric (°F) units).

The Vaisala HUMICAPR2® sensor is immune to particulate and water condensation, oil vapor and most chemicals. The HMP8 Probe includes a chemical purge feature to provide further protection against harsh chemicals.

The HMP8 Probe includes the following:

• 2m high temperature rated cable
• Process connection M22x1.5 (ISO 1/2") or NPT 1/2"
• Traceable 5-point calibration report
• Mounting clips
• Calibration adapter for HMK15 calibrator

A standard ISO 9001 factory calibration certificate is included in delivery. The HMP8 Probe is compatible with Vaisala Insight Configuration Software.

Not included in the package:

• INDIGO transmitter
• Probe extension cables
• Ball Valve
