Hazardous Area Level Sensors
In addition to ATEX and IECEx Certification for their range of hazardous area level sensors and level switches, Deeter are now certified to CSA standards for Explosion Proof Accreditation.
CSA is the Canadian Standards Association which provides product testing and certification for a wide variety of electrical and mechanical products including level sensors for hazardous areas and locations.
Contact T&D for monitoring and level sensing of liquids – products with ATEX and IECEx certification are available including hazardous area float switches, liquid level sensors and load cells.

Hazardous Area Classifications – CSA
hazardous areA locations
in North America
In North America, hazardous area workplaces and locations have traditionally been defined by a combination of Classes and Divisions:
hazardous area Classes
- Class I – a location or area made hazardous by the presence of flammable gases or vapors that may be present in the air in quantities sufficient to produce an explosive or ignitable mixture
- Class II – a location or area made hazardous by the presence of combustible or electrically conductive dust
- Class III – a location or area made hazardous by the presence of easily ignitable fibers or flyings in the air, but not likely to be in suspension in quantities sufficient to produce ignitable mixtures
Hazardous Area Divisions
- Division 1 – a location or area where a classified hazard exists or is likely to exist under normal conditions
- Division 2 – a location or area where a classified hazard does not normally exist but is possible to appear under abnormal conditions
North American transition to the
hazardous area zone system
The U.S. and Canada have recently revised installation codes to recognize an international 3-Zone area classification system for equipment used in hazardous locations.
- Zone 0 – an area in which an explosive gas atmosphere is continuously present for a long period of time
- Zone 1 – an area in which an explosive atmosphere is likely to occur in normal operation
- Zone 2 – an area in which an explosive gas atmosphere does not normally exist
In Canada, all new installations must use the 3-Zone system – existing installations may continue to use the 2-Division system or opt to re-classify using the 3-Zone system.
In the U.S., all installations (both new and existing) can either continue using the 2-Division system or re-classify their product using the 3-Zone system.

Hazardous Area Level Sensors
Deeter are a leading designer and manufacturer of electronic sensors and control systems for level measurement requirements and produce a range of explosion proof level sensors and float switches for use in hazardous area applications.
CSA approval, along with Deeter’s ATEX & IECEx certifications allows the Deeter LVCS FP level sensor and FS FP hazardous area float switch to be suitable for use in hazardous area applications in most regions worldwide.
Deeter ATEX & IECEX Certified Explosion Proof Range
Deeter LVCS-FP is a flameproof continuous liquid level sensor suitable for hazardous area applications and offers accurate level measurement using a magnetic float with a reed switch or Hall Effect sensor stem.Â
Deeter LVCS-FP level sensor is available in standard length sensor stems from 250mm to 2m and can be custom made to suit up to 4 metres.
Liquid Level & Float Sensors
The Deeter F/S- FP is a flameproof float switch suitable for hazardous area applications and offers flexible switching options using a magnetic float with a reed switch or Hall Effect sensor stem.
The F/S FP float switches are available in a number of standard length sensor stems – additionally up to 7 switch points can be fitted on one stem with a mix of normally open / normally closed switches to suit the application.
Explosion & Flameproof Liquid Level & Float Sensors
Both the LVCS FP level sensor and F/S FP float switch are suitable for hazardous area Zone 0, 1 and 2 applications and can be custom made to suit client requirements and still meet ATEX, IECEx and CSA directives.
