FX1901
Compression Load Cell
High Reliability Design for OEM,
Appliance and Medical Applications
10 – 100 lbf Ranges
Compact Coin Cell Package
Anti-Rotation Mounting Features
CE Compliance
DESCRIPTION
The FX1901 units are intended for OEM use in laboratory, hospital or consumer product applications,
establishing a breakthrough price/performance value for compression load cells. The FX1901 is a 1% load cell
device with full scale ranges of 10, 25, 50 or 100 and 200lbf compression. This new, low-cost technology
enables force sensing in a whole new class of "smart" consumer and medical products.
MEAS’ proprietary Microfused™ technology, derived from demanding aerospace applications, employs
micro-machined piezoresistive strain gages fused with high temperature glass to a high performance stainless
steel force measuring flexure. Microfused™ technology eliminates age-sensitive organic epoxies used in
traditional load cell designs, providing excellent long term span and zero stability. Operating at very low strains,
Microfused™ technology provides an essentially unlimited cycle life expectancy, superior resolution, high over-
range capabilities and a ratiometric span of 20mV/V. The combination of stamped flexures and micro
miniaturized MEMs strain gages permits low costs to be achieved in high volume OEM applications ranging
from disposable medical devices to durable appliances and exercise equipment.
