HTZ Smart HART Humidity and Temperature Transmitter from Moore Industries

The HTZ Smart HART Humidity and Temperature Transmitter from Moore Industries simultaneously measures temperature and humidity in processes that require extremely close monitoring of humidity, temperature and dewpoint, example, in clean rooms, assembly areas and storage facilities in the pharmaceutical, semiconductor, food processing, biotechnology and similar industries. HART communications allows the unit to be programmed or queried from any point along one of the transmitter’s dual 4-20mA loops.

The loop-powered (2-wire) HTZ provides exceptional measurement accuracy for humidity, temperature and dewpoint in a single instrument, which eliminates the cost of using multiple transmitters. Accuracy of the relative humidity measurements is up to ±0.75%RH, the temperature measurements is up to ±0.036°C, and the dewpoint calculation is within ±0.5°C.

The HTZ incorporates a sensor module which consists of two parallel probes, one containing a capacitance-based humidity sensor and the other containing a highly-accurate temperature sensor. The sensor module can be mounted on any surface or pipe, such as an HVAC duct or a clean room wall. Either probe can be removed for easy cleaning, calibration or replacement.

The HTZ also incorporates a humidity and temperature display module that can be mounted up to 30 feet away from the sensor module. The display module provides power to the sensor probes and produces two 4-20mA output signals. Each output can be programmed to represent relative humidity, temperature or dewpoint. The display can be programmed to show humidity, temperature, dewpoint, analog output #1, analog output #2 or scroll between the values.
