HTZ
Smart HART® Humidity
and Temperature Transmitter
Introduction
This is the user’s manual for Moore Industries’ HTZ
Smart HART Humidity and Temperature Transmitter.
The HTZ is a loop-powered, HART enabled,
transmitter that measures temperature and relative
humidity and calculates dew point. The HTZ consists
of two specialized components. The Humidity/
Temperature Sensor Module (HSM) has temperature
and humidity probes which can easily be removed
from the housing for replacement or service. The
second component, the Humidity/Temperature Display
Module (HDM), can remain connected to output wiring
when the sensor assembly (HSM) is removed thus
maintaining the output current loops.
The HTZ comes with optional factory trimming
(VTB) that offers higher temperature measurement
accuracy. It is applied to the sensor module (HSM)
and is independent of the display module (HDM).
For ease of viewing, the HSM and HDM may be
placed apart from each other using a dedicated 10ft
(3m) (standard), 20ft (6m) or 30ft (9m) (optional)
cable utilizing quick disconnect connectors at both
ends.
About this Manual
Wherever you see a “Note”, “Caution” or “WARNING”
pay particular attention.
WARNING - Hazardous procedure or condition that
could injure the operator.
Caution - Hazardous procedure or condition that
could damage or destroy the unit.
Note - Information that is helpful for a procedure,
condition, or operation of the unit.
Model and Serial Numbers
Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. The HSM and the
HDM each have a different, unique serial number.
If a problem occurs with your HTZ, check for a tag
listing these numbers affixed to the suspect module.
Supply the Customer Support representative with this
information when calling.
Inputs
The HTZ includes a pre-calibrated relative humidity
sensor and a fixed Pt3850 1000 ohm RTD
temperature sensor. The temperature sensor’s ohms
measurement is linearized to temperature.
Outputs
Analog Outputs
The HTZ is equipped with two analog outputs (-AO1
and -AO2). Both -AO1 and -AO2 are externally
powered (sink only) by 12-42Vdc and output a
4-20mA range with their outputs isolated from each
other.
Both are configurable to output current proportional to
any of the three available input variables (temperature,
relative humidity and dew point).
-AO1
This output powers the HTZ. It provides primary loop
power for the unit. It may be used without -AO2.
HART communications may only be utilized using
-AO1.
-AO2
This output requires its own separate loop power. It
may not be used if -AO1 is not in use.
There is no HART communication capability at this
output.

Dew Point (Dp)= ( (0.66077 – log10 (EW_RH) ) * 237.3) / (log10 (EW_RH) – 8.16077)
This is the saturation vapor pressure over water
Multiply EW with RH
Equation 1. Dew Point Calulation
* High accuracy relative humidity measurements are achieved within a RH range of 33-75% using the trimming feature of Moore Industries’ Intelligent PC
Configuration Software with the RH sensor calibrated against a controlled RH environment (See the -VTRH option under “Sensor Length/Calibration” in Ordering
Information). High accuracy temperature measurements are achieved using the trimming feature of the Intelligent PC Configuration Software with the temperature
sensor immersed in a temperature calibration bath (Sensor-to-Transmitter matching factory calibration; See the -VTB option under “Sensor Length/Calibration”
in Ordering Information). High accuracy dew point measurements are achieved using the trimming feature of the Intelligent PC Configuration Software at 25°C,
between 40-90% RH. Stated accuracies do not include ambient temperature effects. .

HTZ
Smart HART® Humidity
and Temperature Transmitter
Connecting the HTZ to the PC
Connect the RS-232 end of the cable to the PC’s
COM port.
Refer to Table 1 for information on the necessary
equipment.
Connecting the HTZ to the HART
Communicator
Connect the HART modem cable into the loop as
shown in Figure 3.
Once the Configuration Program is installed onto
your PC, the HTZ can be connected to equipment
to simulate input and monitor output. You can then
change the operating parameters of your unit.
No Transmitter Needed
It is not necessary to connect the transmitter to a PC
to create configuration files using the software. The
Configuration Program can be run without connecting
a transmitter, and most parameters can be set
without benefit of input from a HTZ.
This makes it easy to create a set of operating
parameters, save and download them to one or more
transmitters at a later time.
The HTZ must be connected to the PC in order
to: trim input, trim output, assign a tag, perform an
output test, receive (via download) a configuration file
and save the configuration file from the transmitter’s
memory.
Installing the Configuration Software
Refer to Table 1 for the equipment needed.
1. Insert the Moore Industries Interface Solution
Configuration Tools CD into the CD drive of
the PC. Access the CD and open the following
folders: Configuration Software and Tools/HTZ
Configuration Tools/HTZ PC Configuration
Software.
2. Double-click the installation program located
in the folder. Follow the prompts to correctly
install the program.
Configuring the HTZ
One of the benefits of the HTZ is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using Moore
Industries’ Intelligent PC Configuration software or
a HART configurator if using HART communication
capabilities (-AO1 only).
Once these software settings are made, they are
downloaded to the instrument in the form of a Con-
figuration File and stored in the unit’s nonvolatile
memory. You can choose to save a backup copy of
the file on your PC hard drive or external media. The
HTZ communicates with the PC through a proprietary
communications cable via the PC’s serial (COM) port
or using a HART modem cable if HART communica-
tions are used.
