Fixed Gas Detectors

Fixed detectors are the plant's permanent senses: mounted at leak-likely points, they watch around the clock, alarm locally and report to the control system whether or not anyone is nearby. This range is built on two families — the MIC300 series for single-point spans with a wide range ladder, and the MIC100 for up to four gases at one point.

Around those transmitters sit the supporting categories: gas transmitters as the signal layer, alarm controllers for beacons and sounders, and UV flame detectors for open-area fire-and-gas schemes.

Designing a fixed scheme

Start from the gas map: which gases, released where, drifting which way. Detector placement follows density and airflow — hydrogen high, solvent vapours low, toxics at breathing height near the source. The transmitter choice then follows the span needed at each point.

Outputs decide the integration effort: 4–20 mA loops land on almost any panel; RS485 digital points suit networked architectures. The portable-versus-fixed comparison on this site walks through where each detection style earns its money.

Maintenance reality

Fixed points drift and age like any sensor; a fixed scheme includes calibration access in its design — points mounted where a technician with a gas bottle can actually reach them. Modular sensors (MIC100) and standard spans (MIC300) keep that lifetime work predictable.
