Features

Transmitter contains a microprocessor based control circuitry in a plastic case with connection terminals and sensor. Output range is user adjustable. Large dual line LCD is an advantage. Display is possible to switch off. Computerized design ensures long term stability and fail indication. 

 

APPLICATIONS :

  • building HVAC management
  • building HVAC automation
  • museums, archives, galleries
  • air-conditioned rooms 

    Output is set to maximum range from the manufacturer.
    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.

    Application wiring of the 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)
