Wide Range of Installation

Options

The wide variety of measurement

probes, several installation

accessories, and universal mains

and DC power options make the

instruments easy to install in various

locations and kinds of environment;

walls, poles, pipelines, and ducts,

for example. The input/output cable

can be fed through the back of

the transmitter, which is a useful

feature, especially for cleanroom

installations.

The HMT330 series includes six

models:

• HMT331forwall-mounted

applications

• HMT333forductsandtight

spaces

• HMT334forhigh-pressureand

vacuum applications

• HMT335forhigh-temperature

applications

• HMT337forhigh-humidity

applications

• HMT338forpressurizedpipelines

Graphical Display of

Measurement Data and

Trends for Convenient

Operation

The HMT330 series features a large

numerical and graphical display with

a multilingual menu and keypad.

It allows users to easily monitor

operational data, measurement

trends, and access measurement

history for the past 12 months.

The optional data logger, with

real-time clock, makes it possible

to generate over four years of

measurement history, and zoom in on

any desired time or time frame.

The display alarm allows any

measured parameter to be tracked,

with freely configurable low and

high limits.

Versatile Outputs and

Data Collection

The HMT330 can support up to three

analog outputs; an isolated galvanic

power supply and relay outputs are

also available.

For serial interface the USB

connection, RS232, and RS485 can

be used.

HMT330 is also capable of applying

the MODBUS communication protocol

and, together with an appropriate

connection option, provides either

MODBUS RTU (RS485) or MODBUS

TCP/IP (Ethernet) communication.

The data logger, with real-time clock

and battery backup, guarantees

reliable logging of measurement data

for over four years. The recorded

data can be viewed on the local

display or transferred to a PC with

Microsoft Windows

®

software. The

transmitter can also be connected to

a network with an optional (W)LAN

interface, which enables a (wireless)

Ethernet connection. A USB service

cable makes it easy to connect the

HMT330 to a PC via the service port.

Flexible Calibration

The HMT330 instruments are

calibrated at six humidity points

at the factory and come with a

calibration certificate that meets

all the relevant traceability and

compliance requirements.

A quick, one-point field calibration

can be performed with the hand-

held HM70 meter. A two-point field

calibration can be performed,

for example, with the HMK15 salt

bath calibrator in a controlled

environment. The transmitter

can also be sent to Vaisala for

recalibration, and accredited

calibrations are available.

The display shows measurement

trends and over four years of real-time

measurement history.
