Sensepoint Hazardous Area Gas Sensors

The Sensepoint range of flammable, toxic and oxygen gas detectors offerusers a high quality, low cost solution to their industrial gas monitoring needs. Installation in potentially explosive atmospheres is made by the use of a suitable Ex d or EX e approved junction box. The industry standard outputs from Sensepoint are connected to either a choice of Honeywell Analytics’ controllers or 3rd party DCS/PLC systems. both flammable and toxic versions are certified to ATEX and IECEx. The flammable detector is available in either %LEL or PPM detection range versions and provides an industry standard mV bridge output. Typical life expectancy is greater than 5 years, after which the detector is simply replaced with a new one.

The toxic detectors are supplied pre calibrated for easy installation and provide an industry standard 2 wire 4-20mA loop output. User connections are Ex d, while front end Intrinsic Safety (IS) design allows for easy exchange of the replaceable sensor while poweredIS design also removes the need for a sinter enabling very fast speed of response and detection of ‘sticky’ gases such as Chlorine and Ammonia.

The Sensepoint high temperature sensor has been specifically designed for the detection of combustible gases in high temperature hazardous area locations. Typical applications include turbine enclosures and drying ovens used in solvent based printing and coating machines. These applications require a sensor that provides reliable and stable detection allowing lowlevel alarm settings across a wide temperature range.

Utilising a specially matched pair of Sieger poison resistant combustible gas detection elements, the Sensepoint High Temperature Sensor has a very stable baseline allowing alarm trip points to be set as low as 5% LEL across a temperature range of -55°C to +150°C (-67°F to +302°F). The gas measuringrange can be configured from 0-20% LEL up to 0-100% LEL depending on the type of controller used. Sensepoint has proven its suitability across a wide range of demanding applications by delivering high performance and reliability at an affordable cost.
