IE-SNC-T3110-09
General description
The transmitters T3110 are designed for measurement of ambient
temperature and relative humidity of air without aggressive substances.
Measured values are converted to other humidity interpretation: dew point
temperature, absolute humidity, specific humidity, mixing ratio, specific
enthalpy.
Measured and computed values are displayed on a two-line LCD display.
The first line displays temperature
(ºC / ºF). 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 (4 seconds interval)
or to switch off the LCD display at all.
The transmitter communicates by means two galvanically separated current
loop 4-20mA. Each loop has two-wire connection and each loop requires
power from evaluation device. It is always necessary to connect loop I1
which is designed for supplying of measuring part of the device. Using the
configuration software can be assigned to each current loop any measured
or computed value.
All transmitter setting is performed by means of the PC connected via the
optional SP003 communication cable (not included in delivery). Using
TSensor software (see
) you can assign to each
output any measured or computed value and to set its measuring range. It is
also possible to assign both outputs to the same value (with the same range),
if two evaluation devices are necessary to connect. The program supports
make the adjustment of the device too. This procedure is described at file
„
Calibration manual.pdf
“ which is installed commonly with the software.
Device versions:
T3110
transmitter with cable gland for output cable connection
T3110L
device version with watertight male connector instead of a
cable gland for easy connection/disconnection of the output
cable (protection IP67)
T3110Ex
intrinsically safe transmitter for use in potentially explosive
environments
T3110Z
this marking is intended for a non-standard versions of the
transmitters. Description is not included in this manual.
