Common Power
HT7S series loop Powered transmitter series are designed for highly
accurate Humidity and temperature measurement for industrial,
pharmaceutical and building automation applications. They are
available as wall mount, duct mount and flame proof versions.
HT7S series transmitters provides linear output signals proportional to
relative humidity and temperature. HT7S series device are designed to
provide better than 2% RH accuracy and Class A RTD with excellent
long term stability.
Loop Powered 4-20mA DC output signals enables long distance
remote display, recording, controlling or easy interface to PLC/DCS
systems. Two-wire connections allow easy installation directly into air
ducts or within a controlled area. The right choice of the filter cap
enables usage in harsh environmental conditions.
The model HT7S series uses capacitance based sensor for humidity
measurement, that is unaffected by high humidity, dust, fog etc. A
rugged weather proof enclosure is available to monitor space humidity
and temperature.
