Overview
The RPF40+ is a pendulum sensor that hangs on its cable to measure the air temperature in large spaces such as open plan offices, arcades and production plants. The sensor head is 40 mm in diameter. A black ball version for radiant temperature is available in the range. A transmitter in the enclosure converts the temperature to a 0 to 10 V, 0 to 5 V or 4 to 20 mA signal. The measuring range is selectable from eight ranges between -50 and +250 °C. The two parts here have a white sensor head and a 1 m cable.
