Some rather common applications require a hazardous location and even an intrinsically safe operation certification. The CSA Group provides this for products used in North American and around the world. With this rating, TE Connectivity’s HLIR 750 series intrinsically safe, 4-20 mA LVDT position sensors can be used for contact-less measurements in applications in gas turbines for fuel valve position feedback, vane pitch servo controls, governor controls, and generator shell expansion measurement. The sensors have stainless steel construction and a hermetically-sealed sensor body. Specifications for the sensors include measuring ranges from ±2 inches to ±20 inches with maximum linearity error of ±0.25% of full range output.
