Features

Temperature transmitter contains a microprocessor based control circuitry in a durable plastic case with connection terminals. Bult-in precise temperature sensor. Computerized design ensures long term stability and fail indication.

APPLICATIONS - measuring and control of temperature at:

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

Output is adjusted to -30 to +80°C temperature range from the manufacturer.


  Application wiring of the transmitter

Typical application wiring

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)
