Sensors for Explosive Environments

Explosion-proof and hazardous location certified rotary encoders are engineered to perform safely and reliably in environments with potentially explosive gases, vapors, dust, or fibers. As part of the IXARC family of magnetic and optical rotary sensors, these encoders are available in single- and multi-turn configurations, including programmable incremental models. They now comply with a broad range of international and North American safety standards, including ATEX, IECEx, UL, and CCC certifications. This includes suitability for Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G; and Class III hazardous locations, in addition to Zones 1/2 and 21/22. Built for durability, precision, and flexibility, these devices support a wide array of mounting and coupling options to ensure seamless integration into demanding industrial environments.

Explosion Proof Absolute and Incremental Encoders

Explosion proof certified rotary encoders are designed to operate safely in atmospheres where there are potentially dangerous levels of explosive gases or dust. These devices are part of the IXARC family of magnetic and optical rotary sensors and are available in single- or multiturn versions as well as programmable incremental encoders. Rugged, reliable, and highly accurate, these devices can be ordered with a wide range of mounting and coupling options that ensure that they can be installed in zones 1/2 and 21/22 As defined from the ATEX/IECEx/UL/CCC regulations.

Explosion Proof Inclinometers

POSITAL has extended its TILTIX family of inclinometers (tilt sensors) to include explosion-proof models designed to operate safely in environments that contain potentially dangerous levels of explosive dust or gases. These devices have been certified in compliance with IECEx and ATEX directives and are suitable for use in underground mines, oil and gas facilities, agricultural applications, chemical plants, woodworking factories and milling operations.

finderTILTIX Inclinometer Product Finder

Like other TILTIX inclinometers, the new models are available in single (0-360°) or dual-axis (± 80°) versions and feature resolution as high as 0.01° and 0.1° accuracy. Available communications interfaces include J1939, CANopen, Modbus RTU, SSI, and analog output. Analog models can be programmed so that a predetermined range of mechanical motion is set span the full electrical output range. Rugged aluminum and 316 stainless steel housings are offered, with other materials available by special order.These products have been certified to the following ATEX ratings:

Group I (mining):

  • Ex I M2 Ex e mb I Mb

Group II (above ground operations):

  • EX II 2G Ex e mb IIc TX Gb (explosive gases)

  • EX II 1D Ex ta IIIC TX Da IP65 (flammable dust)

  • Zone 1 (Gases/Vapors/Mist)
    An area in which an explosive mixture of the is likely to occur in normal operation occasionally.

  • Zone 21 (Dusts/Powders)
    An area in which an explosive mixture is likely to occur in normal operation occasionally.

  • Zone 2 (Gases/Vapors)
    An area in which an explosive mixture is not likely to occur in normal operation and if it occurs will exist only for a short time.

  • Zone 22 (Dust/Powders)
    An area in which an explosive mixture is not likely to occur in normal operation and if it occurs will exist only for a short time.
