The Honeywell Apex fixed gas sensor takes the best elements of gas detection design and combining them into one unit. Apex provides the highest performance, installation flexibility, a wide range of accessories and a choice of communication outputs. All this is provided in a package that is easy to install, operate and maintain.

Transmitter

The robust hazardous area approved Apex transmitter housing and mounting bracket is made from 316 Stainless Steel. It has a large backlit LCD display, simple 4 button operation, 3 fully configurable relay outputs and selectable sink, source or isolated 4-20mA signal. The sensor and transmitter is common for all gas types.

Sensor

The Apex Sensor can be mounted directly on the transmitter or remotely up to 100m away. The same sensor is used for both catalytic and electrochemical type sensor cartridges.

Smart Cartridge

The sensor can be fitted with a choice of over 40 toxic gas ranges and wide range of detectable flammable gases. Each cartridge is pre-calibrated and simply plugs into the sensor. The Intrinsically Safe design allows cartridges to be changed with the unit under power. The transmitter recognizes a newly fitted sensor cartridge and automatically reads all the configuration information from it.
