Description

Model QLA337 is a custom dual bridge parallelogram load cell designed for medical bag weighing applications. It is offered in a variety of capacities ranging from 2.5 – 15 kg (5.51 – 33.1 lb) and features a dual channel output for high reliability. It is designed as a side-mount load cell for measuring tension forces, and features a very robust mechanical safe overload protection of up to 250 lb (114 kg).


QLA337 Custom Dual Bridge Parallelogram Load Cell, also known as a dual channel load cell, designed to meet the high demands of critical applications in aerospace, medical and others. Equipped with two independent Wheatstone bridges, each fitted with strain gauges, this QLA337 offers unparalleled redundancy and safety features.


With its dual output feature, this load cell not only provides control feedback from one sensor but also allows for data acquisition from the other, ensuring continuous and reliable force measurement and control. Additionally, QLA337 Custom Dual Bridge Load Cell is calibrated to the highest standards of accuracy, with NIST traceable calibration and A2LA accreditation to ISO 17025.

FUTEK’s QLA337 dual bridge load cell meets high levels of SIL (Safety Integrity Levels) or PL (Performance Levels), making it the ideal choice for applications where safety and reliability are of utmost importance. Its redundancy feature ensures that even in the event of a failure in one of the bridges, the load cell will continue to provide accurate load readings and maintain control over the application.
