The Zareba Sensepoint range has Flammable, Toxic, and Oxygen models; all include a junction box with three entries supporting metric and NPT connections. Designed for new installations or retrofitting to existing equipment, supplied pre-wired with a hinged lid for access and is suitable for use in hazardous areas.
Flammable detectors feature catalytic bead poison-resistant sensors that provide a %LEL reading and mV bridge output. Toxic and O2 detectors have Surecell electrochemical sensors that give a two-wire 4-20mA loop output.
A low-cost solution for gas monitoring inside or outside and in potentially explosive atmospheres (ATEX approval only). Depending on individual site standards, the detector can be installed using conduit or armoured cable and glands. Threaded M20, ¾”, and ½” NPT clearance entries are included, each fitted with an appropriate seal, enabling the user to select the most convenient entry size. Versions without junction boxes are available.
Supplied with an earth continuity plate to combat radio interference. Terminals are suitable for use with screened 0.5mm² (20AWG) to 2.5mm² (14AWG) cross-sectional area cable to ensure minimum operating voltage at the detector, depending upon installed cable length.
All Sensepoint gas detectors are pre-configured at the factory for easy installation and do not require calibration during operation. Their industry-standard outputs allow them to be used with Honeywell Analytics Touchpoint controllers or third-party models.
