Midas Gas Detector from Honeywell

Description

Choose the Midas Gas Detector to detect more than 35 gases – easily, quickly and error free. All with extended sensor calibration periods, patented diagnostics and lower cost of ownership. The Midas Gas Detector uses reliable sensor technology to detect many key toxic, ambient and flammable gases in a plant. Thee device monitors points up to 100 fee away while using patented technology to regulate flow rates and ensure error free gas detection. Thanks to Honeywell’s use of advanced robotics, the Midas Gas Detector offers unbeatable quality and reliability.

The Midas is equipped with bright LED lights and an intuitive, interactive interface that provides instant alerts to gas reading or alarm levels. The interface also includes password protected menus for configuration, test and calibration. With it’s compact size and easy to handle metal chassis, installation is very easy. The Midas Gas Detector is complemented by Honeywell’s innovative ChemCassette technology, which detects ultrasensitive toxic gases at low parts per billion (ppb) levels. Honeywell offers 24/7 support of a worldwide network of service engineers. With feature-rich capabilities that are easy to use, the Midas Gas Detector is suitable for many industry applications, including semiconductor processing, light industrial manufacturing, university laboratories, aerospace, wastewater and more.

With flexible features and options, the Midas works right out of the box and configures easily to meet your needs. Each plug and play sensor cartridge is pre-calibrated, so it’s ready when you are. That means longer sensor life, quick and easy  replacement and no operator error due to incorrect or depleted sensors.

The standard power supply and communications capabilities include three onboard relays, 0-22 mA analog output and Modbus/TCP Ethernet digital outputs. Plus, the Midas includes the innovative Power over Ethernet (PoE) protocol – a single Ethernet connection for all power, control and communication requirements. Thanks to the Midas architecture, cost-effective integration with PLC and Fieldbus systems is greatly simplified.

Offered as an option, the Midas Pyrolyzer allows for the detection of NF₃ and other CxFy gases. Cost of ownership is low, as the Pyrolyzer has a replaceable heater assembly with a lifespan of greater than two years. Even more, thanks to the proprietary catalyst to improve efficiency in gas conversion, the Pyrolyzer delivers automatic flow control, temperature control and fast and accurate performance. Additionally, the Pyrolyzer can run from a Midas Gas Det3ector that’s powered by either PoE or 24 VDC.

Ordering Information

Midas transmitters operate with Midas sensor cartridges, for use as a local gas detector. Transmitters are powered by 24VDC or via Power over Ethernet (PoE). Midas provides 0-22 mA analog and Modbus/TCP Ethernet as standard outputs. Integral relays for A1, A2 and fault are included and may be configured normally open or normally closed, latching or non-latching. Transmitters include manual, quick start guide and 1 gland fitting for power in and relays out, 1/4″ x 1/8″ sample inlet tubing (10′), 1/4″ x 3/16″ exhaust tubing (10′) and a sample line tubing duct adapter. Generation 2 features a multi-colored backlight to indicate status.

Higher Temperature Pyrolyzer Midas transmitters  include a snap on Pyrolyzer module that operates with any Midas extractive transmitter. Units are powered via direct connection to transmitter unit. Pyrolyzer includes Pyrolyzer Quick Start Guide and installation screws.

Optional LonWorks interface module that mounts to and connects with any single, universal Midas transmitter with or without Pyrolyzer to provide bi-directional LonWorks connectivity; remote reset and remote control of onboard relays. Unit is 24 VDC powered and provides power and communications directly to the attached Midas transmitter using special ethernet cross over cable (supplied). Includes Quick Start Guide and mounting bracket to the Midas transmitter, rear panel installation screws are not supplied.

Optional; Modbus/TCP to LonWorks converter gateway that can connect up to 4 Midas transmitters (with or without Pyrolyzer) to a LonWorks Network. Requires separate 24 VDC power supply and Ethernet connector cables. Suitable for DIN rail mounting.
