The Vaisala HMP8 relative humidity and temperature probe is designed to be freely adjusted and hot-swapped from pressurized pipelines (< 40 bar) using the Vaisala installation valve. Common applications include compressed air systems, refrigerant dryers, and other pressurized industrial applications. The HMP8's IP66-rated housing makes it suitable for indoor or outdoor use.
With a HUMICAP R2 composite sensor, the HMP8 offers measurement ranges of 0 to 100% relative humidity and temperature from -94 to +356°F (-70 to 180°C). Vaisala's thin-film capacitive technology allows for RH accuracy up to 0.8% and the Pt100 RTD Class F0.1 IEC 60751 temperature sensor provides accuracy up to 0.18°F (0.1°C).
The Vaisala HMP8 is also part of the Indigo product family and compatible with Indigo 201 and 202 transmitters. The HMP8 is plug and play compatible with Vaisala's Indigo series of transmitters, or it can be used as a standalone digital Modbus RTU transmitter over RS-485 serial bus. If analog output is required the probe must be paired with an Indigo 201 transmitter.
