Completely sealed tension sensor is constructed from stainless steel with an IP67 waterproof rating designed for use in a wide variety of tension/force sensing application, even when submerged in water. Also suitable for high force application as well as those application where there is a significant quantity of airborne particulate or chemicals.

Its unique strain-gauge design delivers excellent measurement precision and stability as well as providing maximum overload protection. This sensor is supplied with a 17mm diameter, non-rotating bearing journal typically used with customer-supplied rollers or guide pulleys.

Offered with "FM" Flat Mounting Style or "CM" Cylindrical Mounting Style
