The P30PA resistance sensors of radiant heat are designed to detect and measure the radiant component of heat in larger rooms and halls with a dry environment. The sensors capture the efficient radiant heat component in the monitored space. Good measurement results are only achieved thanks to using black hemispherical sensors. The sensor head is made of plastic material (polycarbonate); it has a terminal block inside for connecting sensors to the system analogue input; the standard analogue inputs used for the measurement should have the range suitable for the Pt1000 (RTD) sensor.

  1. The sensor must be placed is such a way, that the hemispherical surface faces the source of radiant heat, around the place where you want to maintain the desired temperature.

  2. The sensor can be connected to any analogue system input that enables measuring the Pt1000 sensor. The electrical connection of temperature sensors is shown in the examples of connection of a number of peripheral modules, such as connecting the Pt1000 sensor to the AI1 and AI2 inputs of the C-IR-0203M module.
