Transmitter T3113D - duct mount
Programmable temperature and humidity transmitters are equipped with temperature and relative humidity sensors.
Measured values are also converted to other humidity interpretation - dew point temperature, absolute humidity, specific
humidity, mixing ratio or specific enthalpy. Degrees Celsius and Fahrenheit are user selectable. Transmitters are available
in wall-mount, duct-mount and bar types. Also types with T+RH probe on a cable are available. Transmitter contains a
microprocessor based control circuitry in a durable plastic case with connection terminals and sensors in a stainless steel
mesh filter. Humidity transmitters are also available with two galvanic isolated 4-20mA outputs. Configuration of outputs
and output range are user adjustable. Computerized design ensures temperature compensation of the humidity sensor
and fail indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia
against water and condensation.

2) Any value - temperature, relative humidity, dew point
temperature, absolute humidity, specific humidity, mixing ratio or
specific enthalpy can be assigned to each output of dual output
transmitters. Also identical value can be assigned to both outputs.
The T1110 transmitter has only relative humidity output.
Outputs are adjusted to maximum range from the manufacturer.
Output range is user adjustable from the PC by means of the
optional cable SP003 - see photo. Free configuration program for
transmitter adjustment is ready to download anytime from
www.cometsystem.cz.
If different adjustment of outputs and output ranges are required,
please specify required output values (RH, T, Tdp, ..) and required
ranges.
Ordering example: Transmitter T3110, output 1: RH 10 to 90%,
output 2: temperature 0 to 35°C
Ordering example: Transducer T4111, output: -100 to +30°C

1) Maximum temperature only at the measuring end with sensors. Maximum temperature +105°C
for T3111 with cable probe is allowed also for the cable. Near plastic case with electronics maximum
temperature is +80°C. Humidity at temperature over +85°C is limited - see the graph below.
