Description

Spot detectors are designed for smoke detection in explosive objects. The design of the detector provides shielding of the optical chamber with fine-mesh mesh, mechanical performance control device and cable connection with the help of germovodovodov. Explosion protection is realised by means of intrinsically safe electrical circuit.

The detector has explosion protection marking "0Ex ia IIC T6 Ga" and intrinsic safety parameters: "Li: 1 µHn, Ci: 1000 pF, Ui: 28 B, Ii: 14 mA, Ri: 0.4 W" according to GOST 31610.0-2014 (IEC 60079-0:2011), GOST 31610.11-2014 (IEC 60079-11:2011).The principle of operation of detectors of the type ??212-44?? is based on the control of the optical density of the environment by comparing with the threshold value of the amplitude of pulses of infra-red radiation reflected from smoke particles, which are formed by the circuitry of the detector itself.
