Device is designed for measurement of ambient temperature at °C or °F, relative humidity of
air without aggressive ingredients. Measured temperature and relative humidity are recomputed to
humidity expression: dew point temperature, absolute humidity, specific humidity, mixing ratio and
specific enthalpy. Devices T7310 and T7410 support atmospheric pressure measurement at hPa,
PSI, inHg, mBar, oz/in
2
, mmHg, inH
2
O and kPa too. It is possible to set pressure correction for
altitude (offset). Device setting is provided by user’s software, see latter. Devices T3311, T3313
and T7310 communicate via link RS232, devices T3411 and T7410 via link RS485. Supported
communication protocols are Modbus RTU, protocol compatible with standard Advantech-ADAM,
ARION and communication with HWg–Poseidon devices. Devices are preset from manufacturer to
Modbus RTU communication protocol. If you would like to use different communication protocol
then Modbus RTU, it is necessary preset them through user’s software – see latter. Temperature,
relative humidity eventually pressure sensors are non-removable device parts, pressure sensor is
placed inside the electronic case. Measured and computed values are optionally shown on dual line
LCD display. If there are two values displayed at one LCD line, they are periodically switched
between both readings with period of 4 seconds. Display can be switched OFF totally too.
Use user’s software Tsensor for setting of all device parameters (recommended). It is
free to download at
. It supports make the adjustment of the device too. This
procedure is described at file „
Calibration manual.pdf
“ which is installed commonly with the
software. Change of some parameters is possible to do without user’s software with Windows
hyperterminal (change of communication protocol, its parameters, LCD display setting). It is
described in file “
Description of communication protocols of Txxxx series
” which is free to
download at the same address.
Transmitter version T

L
with watertight male connector instead of a cable gland
(RS232) or glands (RS485) is designed for easy connection/disconnection of communication cable.
Male Lumberg connector RSFM4 has protection IP67.
Models marked T

are non-standard versions of the transmitters. Description is not
included in this manual.
Please read instruction manual before the first device connection.
