Hazardous Area Gas Detectors

2-Wire Addressable

Tocsin-750


IGD’s 750 series ATEX gas detectors are the next step in fixed gas detection technology.

IGD’s Sentinel+™ 2-Wire protocol uses a 2 core cable for both power and data communications. Not only fewer terminations, Sentinel+™ 2-Wire protocol has no polarity requirement for its connections. Cable terminations are reduced, No polarity requirements means fewer errors and faster installs.

4-Wire Addressable

Tocsin-903


The TOCSIN 903 ATEX Control Panel provides a local display and control facility for the TOCSIN 102 Series or pellistor gas detectors in Zone 1 and 2 hazardous areas. In addition to being equipped with a 4-20mA process transmitter, the TOCSIN 903 ATEX Control Panel can also be fitted with a serial addressable capability either using the IGD data highway to integrate to a TOCSIN I700 or TOCSIN 920 Series Control Panels, or optionally as a HART device.
