The WS12EX series position sensor by A.C.E. is housing rated IP67 and uses a precision potentiometer for the rotary sensing element. Courtesy: A.C.E.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.

Features include:

  • 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).
