Description

The smart 3 Gr i gae Detectors have been designed to detect combustible and toxic compounds in areas classified as Group1.

At the core of the Smart 3 Gr 1 is a powerful 10 bit microprocessor that provides the following built-in-Features.

Self diagnostic Procedures to control the hardware and sensor correct operation

Zero follower to maintain the detector zero point, from possible drifts caused by thermal or physical variations of the transducer.

Digital Filter employed in the digital analysis of the analogue values sampled.

Hysteresis cycle applied to the outputs associated to the alarm threshold it prevents continuous output switching when close to the threshold values.
