Description

QLA387 is a Miniature Load Button Load Cell in a class of its own. Capable of measuring compression forces up to 500 lb (2224 N) with a footprint of just 0.5 in (12.7 mm) diameter and 0.2 in (5.08 mm) in height, it is an extraordinarily powerful and precise miniature sensor. It features a custom strain element for robust integration with the sensor case, as well as internally embedded zero balance and thermal compensation, allowing for outstanding sensor reliability, accuracy, and performance. The single-gauge design completely eliminates inter-gauge wiring, leading to enhanced calibration performance.

The diverse and durable QLA387 force 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-foot (1.5 m) or 10-foot (3 m) long braided shielded cable. This model can also be modified to suit OEM applications. FUTEK offers application and engineering resources during DFM/DFX stage upon request.
