P3110E Relative Humidity and Temperature Transmitter with 4-20mA Outputs (-30 to +80°C) (0 to 100% RH)

Relative humidity and temperature transmitter is equipped with temperature and relative humidity sensors. 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 transmitters is equipped with two galvanic isolated 4-20mA outputs. 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. Transmitters are 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

Outputs are set to maximum range from the manufacturer -30 to +80°C and 0 to 100%RH.

If different adjustment of outputs is required, please specify required output values RH and  T and required ranges in the order. Adjustment is free of charge.

Ordering example: Transmitter P3110E, output 1: RH 10 to 90%, output 2: temperature 0 to 35°C

Typical application wiring of dual output 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)
Both current loops (I1 and I2) are connected analogically, current loop I1 must be always connected.
