HMT360 Series Intrinsically Safe Humidity and Temperature TransmittersFor operation in up to Zone 0 / 20 Features • Measures humidity and temperature, outputs also dew point, mixing ratio, absolute humidity and wet bulb temperature • Intrinsically safe • Vaisala HUMICAP® Sensor features high accuracy, excellent long-term stability, and negligible hysteresis • Six probe options • Traceable calibration (certificate included) 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, such as zone 0. The HMT360 transmitters' proven performance and technology conform with rigorous international standards. • Safe operation with the entire transmitter in hazardous areas: Division 1 and 2 (USA, Canada), Categories 1G / Zone 0 and 1D / Zone 20 with protection cover (EU) • Designed for harsh conditions • Temperature range between -70 ... +180 °C (-94 ... +356 °F) depending on the probe option 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 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 HMT360 offers six probe options for various applications: • HMT361 - wall mount • HMT363 - confined spaces • HMT364 - pressurized spaces • HMT365 - high temperature • HMT367 - high humidity • HMT368 - 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 dew point in explosive environments. Customized calibration and maintenance contracts for the HMT360 series are available on re
