Product Overview
The Vaisala HUMICAP
®
Wireless Humidity and Temperature Transmitter
HMT140 measures relative humidity and temperature using the connected
probe and analog signals – RTD, Voltage, Current loops and Contacts. It
outputs data via wireless transmitter and is powered with three 3.6 volt DC
batteries and optional 9-30VDC connection and comes in 2 models, with or
without the optional LCD display.
The HMT140 transmitter's output quantities are configurable. Available
quantities are Relative Humidity (RH), Temperature (T), RTD, Contact, mV
and mA. The default output quantities are set at the factory during order time.
These factory preset quantity selections and other wireless parameters can be
changed afterward using the configuration port and included utility if necessary.
The HMT140 is available either with a fixed probe directly attached to the
transmitter housing or a remote probe with different (3/5/10m) cable lengths.
The HMT140 is also available with an optional LCD display without backlight.
It is typically installed mounted on the wall with up to four screws (not
included). Duct installation kits are available as accessories. There is a drilling
template inside the back cover of this guide to help you position the screws
correctly.

Duct Installation Kit
A = Probe (HMP11 )
B = Duct installation kit
C = Probe Cable
1. Pass the probe cable through the plastic pipe of the duct installation kit.
2. Connect the probe cable to the HMP11 .
3. Use a 24mm drill bit to make a hole in the duct wall.
4. Use a 3.2mm drill bit to make four holes for the installation screws
(ST4.2x16-C-Z DIN7981 screw, 4pcs). The holes should be arranged
in a square around the 24mm hole, at a distance of 42mm from each other.
5. Mount the probe holder using the screws (D).
6. Adjust the depth of the plastic pipe and tighten the screw (E)
to lock the probe in place.

batteries.
4. Ensure that the HMT140 Configuration Cable is disconnected.
5. Turn the device on by moving the power switch on the device to the “ON”
position.
HMT140 Utility Installation
Before using the HMT140 Configuration Cable cable to configure the HMT140, the provided
