Macro Sensors Releases HSI/R 750 Series

Macro Sensors released its hermetically sealed position transmitters, the HSI and HSIR 750 series, available with blind bore or through bore with a radial connector. The sensors can determine relative positioning differentials and use the standard of 4-20mA current loop and range from .10-inch to 20-inch, in ¾-inch diameter.

According to the company, these LVDTs (linear variable differential transformers) feature a contactless, frictionless construction, are robust and are easy to clean. The design can be configured for loop-powered two-wire or externally powered three-wire sourcing outputs depending on input/output requirements, and can transmit an output signal over long distances.

The housing of the sensors is all welded stainless steel and has a hazardous location approval from UL and an IEC rating of IP68, meaning the housing is dust tight and can be indefinitely submerged over a meter in depth. Applications included valve position sensing, measuring tank positions and determining movement in infrastructure.
