HMT360 Series Intrinsically Safe Humidity and Temperature Transmitters




Intrinsically Safe

The entire HMT360 transmitter can be installed directly in explosive areas. It can withstand continuous exposure to potentially explosive environments that contain flammable gases or dust.


Customized Configuration

Due to the microprocessor based electronics, options and accessories, the HMT360 series is truly flexible. Customers may specify the transmitter configuration when ordering the instrument, however changes in configuration can also easily be made in the field.


Interchangeable Probes

The HMT360 offers six probe options for various applications:

♦    HMP361 - wall mount
♦    HMP363 - confined spaces
♦   HMP364 - pressurized spaces
♦   HMP365 - high temperature
♦   HMP367 - high humidity
♦   HMP368 - pressurized pipelines


Optimized Sensors

In addition to the standard Vaisala HUMICAP® Sensor, an application specific, very chemically durable sensor is also available.


Long-term Solution

The HMT360 transmitters are an investment; their rugged design, combined with trouble-free operation, ensure a long-term solution for monitoring humidity and dew point in explosive environments. Customized calibration and maintenance contracts for the HMT360 series are available on request.
