Duct Air Temperature RTD

RHV301 / RHV302

Duct Air Temperature RTD sensors have two variants - RHV301 for non-corrosive and non-condensing air and RHV302 for corrosive air. RHV301 has a perforated tip and thin film element for fast response while RHV302 has a closed-tip assembly to protect the sensing element from corrosive, condensing or dusty air. Duct Air Temperature RTD sensors measure temperature between -20 and 65 °C. A light but strong thermoplastic-ABS (Acrylonitrile butadiene styrene) casing withstands varying temperature changes as well as protects the internal mechanism from damage. The wetted part is made of SS316 to ensure long instrument life. Its 3-wire Pt100 RTD element can be constructed in single or dual assembly in Class A as per the IEC 751 standard for RTD sensors. Duct Air Temperature RTD sensors can be designed for horizontal or vertical mounting, as per application requirements. An optional temperature transmitter and cable are also available.
