OPTITEMP TRA-V20 is a resistance temperature sensor (RTD) for measuring outdoor air temperature in industrial areas. The measuring range of this wall-mount HVAC temperature sensor is -50…+100°C / -58…+212°F. Its Pt100 measuring element is placed in the tip of a Ø6 x 0.5 mm / 0.25 x 0.02 inch brass tube for fast response times. The sensor is protected by an aluminium junction box and meets the demands for ingress protection IP65. The OPTITEMP TRA-V20 comes with optional integrated transmitter providing an analogue output signal (4…20 mA or 0…10 V) for the selected measuring range.
