Position sensors for hazardous locations

Positek E111 linear position sensors introduced by Everight Precision Technologies Corp. (www.everightsensors.com) are for use in potentially explosive dust and gas/vapor atmospheres. The E111 is one of the E Series of Positek linear and rotary position sensors that are ATEX approved for Group II service -- suitable for all areas except mining -- and Category 1 GD -- for use in areas with continuous, long or frequent periods of exposure to hazardous gas (Zones 2 to 0) and dust (Zone 20). Operating temperature limits of the sensors are -40 C to +80 C.

With no wearing contacts, the E111 has virtual infinite life, is highly linear and repeatable, and maintains output stability over a wide temperature range. With a 12.7 mm target rod, the sensors are recommended for applications where vibration is an issue or where there is a need for longer travel sensors. E111 sensors are built and calibrated for a measurement range from 50 mm to 600 mm and are offered with a variety of mounting configurations and an optional shaft boot for protection against particle ingestion. Positek E111 Series sensors must be operated with Positek BX barriers that provide either a 0.5 to 9.5 V DC or a 4-20 mA analog output that represents absolute position immediately on power up.
