Instruction manual for use of T0210 transmitter
Transmitter is designed for measurement of ambient air temperature at °C or °F and relative
humidity of air without aggressive ingredients with computing one of the following values: dew
point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
Measuring temperature and relative humidity sensors are non-removable instrument parts.
Measured and computed values are displayed on dual line LCD display. The first line displays
temperature. Value displayed on the second line is selectable among relative humidity and
computed value. It is also possible to display both readings with cyclic overwriting in 4 seconds
interval. It is possible to switch OFF the LCD at all. It is possible to assign measured or computed
value to output Uout1 or output Uout2. Both voltage outputs have common ground with power
source (GND terminal).
All transmitter setting is performed by means of the PC connected via the optional SP003
communication cable (not included in delivery). Program
Tsensor
for transmitter setting is
available to download free at
. Program enables to assign each output
measured value (temperature, relative humidity, computed value) and its range. 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. It is also possible to assign both outputs to the same value
(with the same range), if two evaluation devices are necessary to connect.
Transmitter version T
xxxx
L
with watertight male connector instead of a cable gland is
designed for easy connection/disconnection of the output cable. The protection of male Lumberg
connector RSFM4 is IP67.
Models marked T
xxxx
Z
are non-standard versions of the transmitters. Description is not
included in this manual.
Please read instruction manual before the first device connection.
Device setting from the manufacturer
Transmitter is set from the manufacturer to the following parameters:
value at output Uout1:
relative humidity, range 0 - 10 V corresponds 0 to 100 % RH
value at output Uout2:
temperature, range 0 - 10 V corresponds -30 to +80 °C
display:
switched ON
value displayed at line 2:
relative humidity only
Modification of the setting is possible to do by means of the PC using procedure described
at the end of this document.
Installation of the transmitter
Transmitter is designed for wall mounting. There are two mounting holes at the sides of the
case. It is NOT recommended to use the device for long time under condensation conditions. It
could be the cause of water steam condensation inside the sensor’s cover into water phase. This
liquid phase stays inside sensor’s cover and can’t escape from the cover easily. It can dramatically
increase response time to relative humidity change. If water condensation occurs for longer time it
can cause sensor damage. Similar effect can occur under water aerosol conditions. Don’t connect
transmitter while power supply voltage is on. Interconnection terminals of T0210 are accessible
after unscrewing four screws and removing the lid. Lace the cable through a gland at the case wall.
Connect the cable to terminals with respecting the signal polarity (see figure). Terminals are self-
clamping and can be opened by a suitable screwdriver. For the opening, insert the screwdriver to
upper terminal hole and lever by him. Do not remember to tighten glands and case lid with inserted
packing after cables connecting. It is necessary for warranting of protection IP65. Connect
