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

* 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.
