1 Description of sensors In 1993, the first sensors were tested in practice, and since then they have been continuously improved. Since 2004, the sensors 8xxxx (8KT01, 8KT04) have been produced by iris-GmbH. The sensors 8xxxx contain a passive and an active component, an A/D transformer and a serial interface. The passive component consists of a pyroelectric detector with 6 individual detector elements. The detector is a receiver being sensitive in the infrared wave range from 9 to 12 µm. Every body emits thermal radiation corresponding to its temperature. The wave range from 9 to 12 µm is...

Photo of the sensor 8KT01, scale approx. 1:2 • This sensor has a shielded, 1m long, halogen-free cable prepared with a circular connector. o The cable meets the following specification: Cable length: 1m (90...110cm) Halogen-freedom according to DIN VDE 0472 part 815 Corrosiveness of the combustion gases: DIN EN 50267 is met (substitute of DIN VDE 0472 part 813) o Data of the circular connector: Pinout according to DIN 45326 Socket, 8 poles Metal housing, screw plug For connecting this sensor to the analyzer A21S-2 or A21S-2-GLORIA, an additional cable is required. The cable identification...

Sensor type 8KT01: Detection range In the following, the detection range of the sensor type 8KT01 is shown with its two curtains • • for a narrow door and for a wide door. On the left side, the detection range of the passive component of the sensor, and on the right side, the detection range of the active component of the sensor is shown in three views: 1. The upper views show the detection range of the sensor from the side. 2. The central views show the detection range of the sensor from outside (view on the door). 3. The lower views show the detection range of the sensor from above (view...

Photo of the sensor 8KT04, scale approx. 1:2 • • This sensor has a shielded, 5m long PVC-containing cable prepared with a Micro-D-Subconnector. For connecting this sensor to the analyzer A21S-2 or A21S-2-GLORIA, no additional cable is required. => However, extension cables are not provided either. The photo shows on the left the cable of the sensor 8KT04 with Micro-D-Sub-connector on the right the analyzer A21S-2 with Micro-D-Sub-connector. The maximum cable length between analyzer A21S-2 or A21S-2-GLORIA and sensor (including the cable at the sensor) amounts to 15m. This sensor has been...
