Air humidity sensor t003a SMARH

relativeclosed circuitcapacitive

SMARH provides accurate and reliable measurements of relative air humidity. The sensing component features a laser-cut polymer capacitive transducer with an integrated signal conditioning system on an electronic board. The sensitive element is inserted in a filtering structure which offers excellent resistance even in critical operating conditions due to the presence of water, dust, dirt, oil or chemical products. This expedient makes the sensitive element more immune to aging and, consequently, to reconditioning and calibration. The transducer is protected from the external radiation by a special non-hygroscopic screen made of an intrinsically anti-UV plastic material. Moreover, thanks to its curvy-shape in section the internal natural ventilation is improved, ensuring an ideal environment of measure. The sensor is supplied with power and signal cable (4 m).
