TRUERH™ Series HT-670x Humidity Transmitters

TRUERH™ HT-670x Series Humidity Transmitters
come in both wall or duct mount packages to meet a
variety of sensing application needs. These attractively
styled controllers offer ease of installation and
application flexibility.
The transmitter generates a jumper-selectable output
signal in either the 4 to 20 mA or 0 to 10 V range,
corresponding to 0 to 100% Relative Humidity (RH).
TRUERH transmitters can measure Relative Humidity
(RH) within either ±2% or ±3% accuracy. The 2%
models include a National Institute of Standards and
Technology (NIST) certificate of conformance. The
patented All-Polymer™ humidity sensor construction
improves resistance to chemical corrosion.

Features and Benefits
❑ TRUERH Technology Features patented improvements in circuitry and calibration techniques
❑ All-Polymer Humidity Sensor Provides accurate and reliable humidity sensing with the patented sensing element
❑ NIST Traceable Calibration Meets NIST standards for calibration testing, verifying, and auditing for the 2% model
❑ Jumper-Selectable Output: 0 to 10 VDC or 4 to 20 mA Maximizes application flexibility
❑ All-Plastic Material for Duct Probe Improves thermal performance and complies with Underwriters Laboratories® Inc. (UL) flammability ratings for plenum use

Product Overview
IMPORTANT: The HT-670x Series Humidity
Transmitters are intended to provide input to
equipment under normal operating conditions.
Where failure or malfunction of an HT-670x Series
transmitter could lead to an abnormal operating
condition that could cause personal injury or damage
to the equipment or other property, other devices
(limit or safety controls) or systems (alarm or
supervisory) intended to warn of, or protect against,
failure or malfunction of the HT-670x Series
transmitter must be incorporated into and maintained
as part of the control system.
The HT-670x Series wall mount and duct probe
humidity transmitters use a patented All-Polymer
sensor capable of sensing the entire range of
0 to 100% RH. Both transmitters feature a
quick-mount, two-screw design that saves time and
simplifies installation.
A combination wallbox and surface mounting base
connects to the unit for easy mounting directly to either
drywall (spring clips provided) or a standard U.S.
wallbox. All wiring connections for the humidity
transmitters terminate on terminal blocks.
The Johnson Controls TRUERH duct package offers an
all plastic enclosure, which reduces thermal biasing.
This results in improved accuracy.
