Position sensor for combustible dust
The WS12EX series position sensor by A.C.E. is housing rated IP67 and uses a precision potentiometer for the rotary sensing element.
In locations where combustible dust is present, the maximum allowable surface temperature of installed devices is limited to only 2/3 of the minimum ignition temperature of the surrounding combustible dust. If there is a risk of dust accumulation, further considerations such as the smoldering point of the dust and additional temperature safety distances must be evaluated. The WS12EX series was developed to meet these safety requirements related to combustible dust.
- Housing rated IP67
- Industry standard analog outputs: 0-10 V dc and 4-20 mA
- Linearity: +/- 0.10 % (optional +/- 0.05 %)
- Precision potentiometer is utilized for the rotary sensing element.
The WS12EX series achieves the requirements of EX Dust Explosion-Proof, Zone 22 for non-conductive dust. The WS12EX series was designed for numerous industries where combustible dust is present: saw mills (saw dust), food processing (flour dust) and other harsh application (carbon dust).

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
