Honeywell Midas

The Honeywell Midas gas detector is designed for high‑tech semiconductor processing, advanced industrial manufacturing, research laboratories and critical infrastructure. A robust extractive pump system draws samples from points up to 100 feet (30 m) away, enabling continuous monitoring of hazardous or hard‑to‑reach areas without placing electronics directly in the gas stream. A nominal 500 mL/min sample flow and fast transport times support rapid alarm response when process conditions change.

More than 35 sensor options allow one platform to cover a broad range of toxic, ambient and flammable gases used in semiconductor fabs, light industrial plants, university laboratories, aerospace facilities and wastewater treatment plants. Available sensor chemistries target key process gases, while optional Midas Pyrolyzer modules extend detection to challenging species and perfluorinated compounds used in advanced etch and clean processes.

Patented flow regulation and robust sensing technology underpin stable, error‑resistant measurement. Reflex® automatic sensor health checks continually assess sensor integrity, and TempraSure™ temperature compensation helps maintain accuracy as ambient conditions vary. Internal air and inline particulate filters, plus optional end‑of‑line and Freon filters, protect the sampling path and sensing elements when dealing with corrosive, dusty or aggressive gas streams.

Event logging of alarms, faults and sensor history supports troubleshooting, incident review and audit requirements. CE and UKCA markings, compliance with key international safety and EMC standards and immunity to radio frequency interference make Honeywell Midas suitable for regulated, electrically noisy industrial environments where traceability and reliable performance are critical.

The compact, small‑footprint metal chassis allows installation where panel space is limited, including crowded tool bays, service chases and control cabinets. Durable metal and painted steel housing and brackets suit industrial use, while support for duct, wall, DIN‑rail and bracket mounting enables consistent hardware across different tool sets and plant layouts.

The transmitter is engineered for simple, fast installation to minimise commissioning time and disruption. Accessories such as weather shields, L‑brackets, vented top covers and PoE switches help adapt the detector to site conditions, reducing the need for multiple detector types and simplifying project engineering and spares management.

Honeywell Midas uses factory‑calibrated, plug‑and‑play sensor cartridges to reduce the frequency and complexity of field calibration. This approach shortens service interventions, reduces technician exposure at the point of use and lowers the risk of errors during replacement. Each smart cartridge stores an on‑board e‑calibration certificate, providing traceable calibration data for quality systems and regulatory documentation.

Over 35 sensor cartridge options are available, with cartridge and kit variants offering different warranty durations and configuration convenience. Sensor cartridges and transmitter kits enable cost‑effective expansion or replacement without changing the base transmitter, supporting long‑term platform standardisation. A robust, long‑life extractive pump with a typical two‑year service interval, together with clearly defined component lifetimes, supports planned maintenance programmes and predictable lifecycle costs.

A bright multicolour backlit LCD and status LEDs provide clear indication of normal, warning and alarm states at a glance. The icon‑driven interface and four‑button keypad simplify local navigation for configuration, calibration and bump testing.

Password‑protected menu levels restrict changes to authorised personnel, helping to safeguard alarm setpoints, calibration parameters and test routines. Remote browser access over Ethernet allows authorised users to check status, adjust settings and run diagnostics from a PC or handheld device, reducing the need for physical access to the detector, particularly in crowded or restricted tool areas.

Honeywell Midas is built for straightforward integration into both new and existing control architectures. Three built‑in Form C relays (Alarm 1, Alarm 2 and Fault) provide direct activation of external sounders, beacons and shutdown or interlock functions, supporting layered safety strategies that combine local annunciation with automated process actions.

An isolated 0–22 mA analogue output with fault and event signalling ties easily into standard control loops, while Modbus/TCP Ethernet enables digital connectivity to PLCs and plant monitoring or building management systems. Power over Ethernet (PoE) allows power and communications over a single cable, simplifying wiring in dense tool bays and retrofit projects. Optional LonWorks interface modules, including a quad gateway that connects up to four Midas transmitters, provide direct integration with LonWorks‑based building and process networks.

Honeywell Midas benefits from Honeywell manufacturing quality and advanced robotics to deliver consistent detector and sensor performance over its service life. The platform builds on an established heritage of extractive gas detection technology previously supplied under the MDA Scientific brand, providing a mature, field‑proven solution for semiconductor, industrial and laboratory environments.

Combined with comprehensive documentation, clearly defined maintenance intervals and support from authorised service providers, Honeywell Midas offers a stable foundation for fixed gas detection projects and long‑term service programmes across complex, multi‑site operations.
