Air Temperature & RH% Transducer

TTEPRH is a combined sensor for measuring air temperature and relative humidity. Temperature measurement is taken using a platinum Pt100 resistance thermometer with a response curve, compliant with the DIN 43760 Class 1/3 standard and 4-wire connection.
The humidity measurement is obtained using a laser-cut capacitive polymer transducer connected to an electronic signal conditioning board. The sensor is offered either in the TTEPRH-N version with natural temperature output (4-wire pt100) and 0-1 V output for humidity, or in the I, V, S, 12 versions (respectively in current, tension, serial Modbus and serial SDI - 12 outputs).
Serial versions (Modbus or SDI-12) can provide, in addition to the temperature and humidity values of the air, also the the values of dew and frost points. The sensor body is made out of corrosion-resistant aluminum alloy and stainless steel screws. A non-hygroscopic and UV-stabilized plastic screen protects the sensing element generating at the same time a ventilated environment. This allows the sensor to have a proper functioning not affected by sunlight.
The sensor is supplied with power and signal cable (4 m).
