Temperature, relative humidity and dew-point transmitters with 0-10V output are available in wall-mount and duct-mount types. Transmitter contains a microprocessor based control circuitry in a durable plastic case with a connection terminals and a humidity sensor in a bronze sintered filter. Transmitters are available with temperature output 0-10V and humidity output 0-10V. Configiration of outputs and output range are user adjustable. Large dual line LCD for simultaneous display of T+RH, or dew-point temperature is an advantage. Display is possible to switch off. Computerized design ensures maximum long term stability, 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. Transmitters are designed for use in non-aggressive environment.

APPLICATIONS - measuring and control of air relative humidity at:

COMMON TECHNICAL PARAMETERS
Air relative humidity range: 0 to 100%
Accuracy of relative humidity measurement: ±2.5% relative humidity from 5 to 95% at 23°C
Accuracy of temperature output: ±0.4°C from -30 to +100°C
±0.4% from reading over +100°C
Accuracy of dew-point temperature output: ±0.5°C from 30 to 95% RH (calculated from temperature and RH)
Temperature operating range of case with electronics: -30 to +80°C
Temperature operating range of LCD display: readable to operating temperature +70°C, it is recommended to switch OFF the LCD over +70°C
Range of RH sensor temperature compensation: -30 to +125°C
Voltage outputs: 0-10V, outputs are not galvanic isolated - have common ground
Configuration of outputs and output range: user adjustable from the PC
Filtering ability of sintered bronze sensor cover: 0.025mm
Protection of the case with electronics: IP65 electronics, IP40 sensors
Power: 15-30Vdc, maximum consumption 20mA
Warranty: two years

Tdp .. dew-point temperature

* Maximum temperature only at the measuring end with sensors. Relative humidity at temperature over +85°C is limited in accordance with the graph. Near plastic case with electronics maximum temperature is +80°C.

** Any measured value (T, RH, Tdp) can be assigned to each output. Also identical value can be assigned to both outputs (e.g. humidity + humidity). Outputs are adjusted to maximum range from the manufacturer. Output range is user adjustable from the PC by means of the optional cable - see below. Free configuration program is ready to download 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. Minimum full scale is 30°C or 30%RH.

Ordering example: Transmitter T0210, output 1: RH 10 to 90%, output 2: temperature 0 to 35°C
