The Pt100 sensor of RTD-830 series is designed for use as a surface temperature sensor. The aluminium housing allows for fast transfer of heat to the sensing element. The housing contains a 2.8 mm diameter hole so the sensor can be bolted or cemented into place. If bolt mounted, a small amount of Omega's OT-201 High Conductive Paste placed between the housing and surface can improve thermal response. The sensor includes a 100 ohm Class A DIN Platinum element connected to 1 metre of PFA insulated cable and a 3-pin mini plug and socket.
