Description
FX1901 Compression Load Cell
The FX19 units are intended for OEM use inlaboratory, hospital or consumer product applications,establishing a breakthrough price/performance value forcompression load cells. The FX19 is a 1% load cell devicewith full scale ranges of 10, 25, 50 or 100 and 200lbfcompression. This new, low-cost technology enables forcesensing in a whole new class of “smart” consumer andmedical products.MEAS’ proprietary Microfused™ technology,derived from demanding aerospace applications, employsmicro-machined piezoresistive strain gages fused with hightemperature glass to a high performance stainless steelforce measuring flexure. Microfused™ technologyeliminates age-sensitive organic epoxies used in traditionalload cell designs, providing excellent long term span andzero stability. Operating at very low strains, Microfused™technology provides an essentially unlimited cycle lifeexpectancy, superior resolution, high over-rangecapabilities and a ratiometric span of 20mV/V. Thecombination of stamped flexures and micro miniaturizedMEMs strain gages permits low costs to be achieved in highvolume OEM applications ranging from disposable medicaldevices to durable appliances and exercise equipment.
