HMT360 -- Intrinsically Safe Humidity and Temperature Transmitters

Published on : Tuesday 30-11--0001

The Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT360 are the ideal solution for measuring humidity in hazardous areas. They operate safely and reliably even in the most hazardous classifications. The HMT360 transmitters' proven performance and technology conform with rigorous international standards

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

The interchangeable probes enable fast and easy removal or re-installation when required.

Calibration, for example, is easy to perform due to the modular structure.

All calibration coefficients are included in the probe unit itself, which means that probes can be switched between transmitter bodies without losing the accuracy.

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 dewpoint in explosive environments.

Customized calibration and maintenance contracts for the HMT360 series are available on request.
