Force Indicating Washer
Load_WasherTactile Pressure Indicating Sensor
The Tactilus® force indicating washer is a revolutionary new means to measure and assess bolted joint tension, design and efficacy. Unlike traditional strain gauged load cells and force washers, The Tactilus® force sensor is extremely thin, non-invasive and highly economical. The Tactilus® force sensor system is a valuable aid in R&D.
Upon the application of tension the Tactilus® force indicating washer reveals precisely how much force (tensile load) is being applied at the interface of the bolt and flange surface and how this force is circumferentially distributed.
With Tactilus® you only have to invest once in electronics and as your bolt tension monitoring evolves, only the custom tailored sensor element need be adapted.
Tactilus® Technology
Tactilus® is a tactile surface sensor. Essentially an “electronic skin” that records and interprets pressure distribution and magnitude between any two contacting or mating surfaces and assimilates that data collected into a powerful Windows® based tool kit. Each Tactilus® sensor is carefully assembled to exacting tolerances, individually calibrated and serialized. Tactilus® employs sophisticated mathematical algorithms that intelligently separate signal from noise, and has advanced electronic shielding techniques to maximize environmental immunity to electromagnetic noise, temperature and humidity.
“The Tactilus® force indicating washer is the most economical, scientific and user-friendly system for bolt tension evaluation available today.”
