Dual-Power-Level Amps Target Strain-Gauge Sensors

May 23, 2016
General-purpose analog amplifiers enable inline amplification for full-bridge, metal-foil strain-gauge-based sensors.

General-purpose analog amplifiers recently developed by FUTEK enable inline amplification for full-bridge, metal-foil strain-gauge-based sensors. The The IAA100 and IAA200 have up to a 10-millivolt per volt output (mV/V), built-in DIN-rail clips (DIN stands for the German industrial standard “Deutsche Industrie Norm”), and removable screw terminal blocks on the input and output.

Inside the devices are eight dual-inline-package (DIP) switches for shunt selection. The DIP switches allow up to 256 different shunt values to simulate measurements at various points across a strain gauge in order to verify that the sensor meets specifications.

Bandwidth is adjustable to 1 kHz, 10 kHz, or 25 kHz for both the IAA100 and IAA200. They include two levels of power delivery to sensors; a switch can change the polarity of the output signal. The amplifiers RoHS-compliant and Conformite Europeene (CE) approved. They meet the CE Criteria A Certification—showing no change in performance while operating as specified by the manufacturer—used in aerospace and medical-grade devices.
