Hazardous Locations

Speed Measurement Solutions for Hazardous Areas

A dangerous failure of one critical component located in a hazardous area can result in the loss of a complete plant. JAQUET speed sensors & supporting equipment are designed & qualified to up to date international standards where flammable gas or explosive dust may be present.

Not all hazardous area applications are the same. That’s why JAQUET offers 5 different speed sensor families to choose from. Comprehensive selection, usage & certificate data are supplied for each range to ensure the right solution is used under correct operating conditions.

Certified to US standards for either Class 1 Division 1 & 2, Groups C & D or Class II, Division 1 & 2, Groups E, F and G, these VR sensors are available in sizes of M10, M12, 3/8”, 5/8” and ¾”.

Where conformance with Ex-ATEX standards is required, the VR DSE series is available in M16, M18, M22 and 5/8” – 18 UNF housings.

Hall Effect DSF series in M12…M22 and 5/8” – 18 UNF are suitable for use in flammable gas & dust atmospheres to Ex II 2G Exia IIC T6.

Differential Hall Effect DSD series are provided in M10 housings for pole wheels down to Module 0.5.

Active Eddy Current DSH series are offered for aluminium targets & having separate sensor head and electronics. This has advantages where the sensor head may be exposed to high temperatures.

Customer specific solutions are offered where any of JAQUET’s tachometers, isolators or barriers are built into explosion proof housings for installation in the hazardous area.
