Features

Transmitter contains a microprocessor based control circuitry in a durable plastic case with connection terminals and sensors in a filter with stainless steel mesh. Humidity transmitter is equipped with 4-20mA output. Output range is user adjustable. Large dual line LCD is an advantage. Display is possible to switch off. 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. Transmitter is designed for use in non-aggressive environment.

 

APPLICATIONS - measuring and control of air humidity at:

  • building HVAC management
  • building HVAC automation
  • warehouses
  • glasshouses
  • manufacturers
  • museums, archives, galleries
  • air-conditioned rooms
  • weather stations

Transmitter is approved and homologated by
RENAULT and by PSA (PEUGEOT / CITROEN) car manufacturers.

Output is set to maximum range from the manufacturer 0 to 100%RH.
To set other range by the user buying of SP003 cable is necessary - see Optional accessory.
Free configuration program TSensor for transmitter adjustment is ready to download anytime.

If different adjustment of output is required, please specify required output range in the order. Adjustment is free of charge.

Ordering example: Transmitter T1110, output: RH 10 to 90%

Application wiring of the humidity transmitter
 

Typical application wiring of transmitter

Calculation of minimum power voltage Uss for proper operation:
Uss min> Uo min + Imax * Rz,
where: Uo min= 9 V
Imax... approximately 20 mA
Rz... sensing resistor (shunt)
