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 and T1 design to the high range
1.25” diameter
B2 package, the ELAF provides exceptional flexibility and
superior performance.

ELAF LOAD CELL
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, FEP/PTFE 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 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.

3.
For bodies B0, B1, and B2, compression force produces a positive signal.
For bodies T1 and T2, tension force produces a positive signal, and default calibration (without option AC) is in tension mode.
For amplified output, 5Vdc supply. AMP module is external on cable except on body B2. (Consult factory for higher supply voltage.)
