LLB250 is a Miniature Load Button in a class of its own. Capable of measuring compression forces up to 250lbs with a footprint of just 0.5” (12.7mm) diameter and 0.15” [3.9mm] in height, it is an extraordinarily powerful and precise miniature sensor. It features a custom single-gauge design for robust integration with the sensor case and very high accuracy and reliability. The single-gauge design completely eliminates inter-gauge wiring, leading to enhanced calibration performance. A customized strain element allows increased strain measurement around the active sensor element that reduces reproducibility errors and installation mishaps.
The diverse and durable LLB250 sensor is designed for press or inline compression applications, such as measuring loads on a turbine shaft or gauging forces on a CNC workpiece. The sensor has a highly flexible 34 AWG, 4-conductor, 5-feet [1.5 m] long braided shielded cable. FUTEK also offers custom sensor versions that can be optimized to meet your requirements.
