The Midas® gas detector is an extractive gas sampling system that draws a sample locally or from a remote point to a sensor cartridge that is located inside the detector's chassis. A wide range of Asphyxiant, Toxic, Flammable, Pyrophoric, Corrosive, and Oxidizer (including Oxygen) gas sensor cartridges are available that enable detection of gases used or generated in the Semiconductor and other industries.
Midas® is wall mounted and displays gas concentration, alarm, fault and status information via its backlit LCD and LEDs. A simple to use 4-button keypad located under the display provides the facility to set-up, review, operate and make changes to the detector's configuration.
Midas® has flexible power and communications capabilities built in as standard. These include 3 on board relays, 0-21 mA analog output, Modbus/TCP outputs for signal and service connectivity as well as the innovative Power over Ethernet (PoE) connection that enables a single Ethernet connection to be made for all power, control and communication requirements. An optional LonWorks® interface is available.
The Midas® gas detector comprises of 4 parts: the main chassis, the mounting bracket assembly, the sensor cartridge and the unit cover. Diagram 2-1 details the Midas® general arrangement. Additionally, optional Pyrolyzer modules for the detection of NF3 or various PFCs and an optional LonWorks® module are available.
