Gas detection normally arrives as a separate vendor, a separate panel and a separate screen nobody logs into. These detectors share one body, one wiring standard and one spares inventory across more than thirty gases, with the sensing cell setting the target and range. The relays trip locally with no network involved, and the same reading goes to a cloud that keeps the record and raises the alert.
The same detector body serves a pumping station, an animal house and a product somebody else puts their name on. What changes is the sensing cell and how deep the integration goes.
Wastewater plants, pumping stations, chemical and fuel storage. Continuous toxic and combustible monitoring, local alarm relays that trip without a network, a 4-20 mA loop into the panel that is already installed, and a logged record of every excursion.
Ammonia in animal housing, CO2 in enclosed growing and storage, methane around digesters, oxygen in controlled-atmosphere rooms. Detection on the same bus as the climate and process sensors already in the building, with relays that stage fans before a reading becomes a loss.
You are building a safety or environmental product and need detection as a component rather than as a project: one detector body covering dozens of gases, one wiring standard, and a cloud carrying your name rather than ours.
Every detector shares the same flameproof housing, LCD, relays, and outputs. The cell inside sets the target gas, range, and resolution. Selectable ranges below; the right range for your application is part of the scoping conversation.

Gas detection has a hard requirement most sensors do not: the alarm must work even when the network does not. The platform layers cloud on top of local interlocks instead of replacing them.
Two configurable alarm relays per detector, normally open dry contacts. Fans, solenoids, and sirens trip locally with no network dependency.
The analog loop feeds PLCs, DCS, and legacy alarm panels directly. The detector drops into an installed base without replacing it.
Digital readings stream over Modbus-RTU into our industrial IoT controllers, joining every other sensor on the site: climate, level, water quality, energy.
Concentration curves, threshold alerts to the right person by severity and shift, exportable excursion logs, and REST plus MQTT APIs for your MES or reporting stack.
A gas reading is most useful next to the rest of the site's data: ammonia beside house temperature and ventilation state, methane beside digester process data, oxygen beside cold-room door events. Because the detectors join our controllers over the same Modbus bus as every other sensor, that context comes built in: one dashboard, one alert routing policy, one API, one brand on the app your operators open.
The detector body, display, outputs, and enclosure are identical across the family; the sensing cell inside sets the target gas and range. That means one spare-parts inventory, one integration, and one wiring standard across every gas point on a site. Cells are replaceable at end of life without changing the installation.
Each detector outputs 4-20 mA, RS485 Modbus-RTU, and two alarm relays in parallel. The Modbus output connects to our industrial IoT controllers alongside any other sensor on the site, streaming to the cloud for dashboards, alerts, and APIs. The analog loop and relays serve existing panels and local interlocks at the same time.
No. The two relays are driven locally by the detector against its configured set points. Ventilation, shutoff, and sirens trip even if connectivity is down; the cloud layer adds logging, remote visibility, and escalation on top.
Yes. Detection sits on the same multi-tenant cloud as everything else, so the dashboard and the mobile apps carry your name and your customers sit in your tenant rather than in ours.
The detectors are built in flameproof aluminium enclosures designed for hazardous-area installation, with IP65 sealing for washdown and outdoor sites. Certification documentation for your market and installation class is scoped per engagement.
It starts with the gas points: which gases, at what ranges, how many, and what they have to report into. Most sites begin with a handful of detectors on the points that already worry someone before extending to the rest.
Which gases, at what ranges, how many points, and what panel or controller they have to report into. We come back with the cell and range to specify and how the detectors wire into what is already there.
