HMT331 Humidity and Temperature Transmitter

for Demanding Wall-Mounted Applications

The Vaisala HUMICAP

Humidity and

Temperature Transmitter HMT331

is the top-of-the-line wall-mounted

transmitter for demanding HVAC and

condition monitoring applications.

Compared to regular wall-mounted

transmitters, the HMT331 offers,

higher measurement performance,

better chemical tolerance, advanced

graphical display features, more

powering options, more output

options and a wider variety of output

humidity parameters.

Features/Beneﬁts

▪

For temperatures -40 ... +60 °C

(-40 ... +140 °F)

▪

Application examples:

cleanrooms, pharmaceutical

processes, greenhouses,

swimming halls, museums and

archives

The HMT331 is the state-of-the-art wall-mount humidity instrument.

Graphical display of

history and

measurement trends

The HMT330 series features a large

numerical and graphical display,

allowing users to easily monitor

operational data, measurement trends

and one-year measurement history.

The optional data logger with real-

time clock makes it possible to

generate over four years of measured

history, and zoom in on any desired

time or time frame.

Outputs and power supply

options for every need

The output options include three

analog outputs, RS-232, RS-485, and

alarm relays.

The voltage supply range is from 10 to

35 VDC. With an additional module,

the transmitter can be connected to

all universal mains AC supplies.

The input/output cable can be fed

through the back of the transmitter,

which is a useful feature, especially

for installations in cleanrooms.

The Vaisala HUMICAP

Humidity and

Temperature Transmitter HMT333 is

a versatile instrument for applicatons

where a small remote probe is

needed.

Flexible installation

To install the probe in ducts,

channels and through walls, an

installation kit is available with an

aluminum ange, lead-through piece,

and steel support bar.

HMT333 has two probe cable

options available, a exible one that

withstands heat up to +80° C, and a

durable cable that withstands heat

up to +120° C. Both cable options are

available in lengths of 2, 5, and 10

meters.

Features/Beneﬁts

▪

For remote probe installations

in demanding HVAC

applications

▪

For temperatures -40 ... +80 °C

(-40 ... +176 °F) or

-40 ... +120 °C (-40 ... +248 °F)

▪

Small thermal mass - fast

response to temperature

changes

▪

Application examples:

cleanrooms, pharmaceutical

processes, greenhouses,

environmental chambers

The HMT333 transmitter has a small probe for remote applications.

For outdoor environments, the

DTR502B solar radiation shield

provides protection for the probe.

The shield can be installed on a pole,

a beam or a at surface.

For moderate humidities

and temperatures

The HMT333 is typically used in

demanding HVAC applications such

as cleanrooms, pharmaceutical

processes, and greenhouses, or in

processes of moderate temperature.

For environments with continuously

high humidity, the HMT337 with a

warmed, vapor-tight and stainless

steel probe is recommended.
