ELAF Load Cell Compact Design: 0.5”, 1.25” and 1.5” Diameter 10 5000 lbf High level and mV Output High Stability Industry Standard Packaging Resists Off Axis Load Components Full NIST Traceable 11 Point Calibration Shileded Teflon Cabling with Strain Relief DESCRIPTION The ELAF series compression load cells raise the bar for high performance at low cost. Measurement Specialties 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 utilizes strain gages providing gage factors greater than 100, an essentially unlimited cycle life expectancy, superior resolution, exceedingly high over-range capabilities (without the need for stops) and an amplified ratiometric high level 0.5 to 4.5 V output or 20 mV/V bridge output. Microfused sensors are ideal for your test and measurement applications. From the ultra compact 0.5” diameter B0 design to the high range 1.5” Diameter B3 package, the ELAF provides exceptional flexibility and superior performance. Measurement Specialties ELAF Test and Measurement series sensors, unlike most designs, are provided with a “four-bar“ design where a flexible diaphragm parallels the measuring flexure. This configuration is far less susceptible to off-axis load components than single diaphragm traditional designs. Shielded, teflon insulated instrumentation cabling is provided along with spring steel strain reliefs and full NIST traceable calibration certificates. The ELAF unit is fully thermally compensated and will provide an essentially unlimited cycle life expectancy. The ELAF can be configured with a variety of options to fine tune the instrument to your application: select from several standard package geometries. Compensated temperature ranges, input voltages, lead lengths or specify entirely unique combinations of these options.
