The new in-line strain gauge amplifier from Mantracourt Electronics is set to streamline the calibration of a sensor thanks to its digital potentiometers and extremely simple and intuitive toolkit.

Designed to convert strain gauge or load cell inputs into a 4-20 mA output, the in-line strain gauge analogue amplifier provides more filtering than the existing embedded strain gauge amplifier range (ICA), and due to its small design, it can be easily integrated into compact installations. It is compatible with a wide range of inputs including strain gauges, load cells, pressure and torque transducers. The ILA benefits from several important features including stable, high accuracy measurement with low drift and extensive EMC filtering. Reverse polarity protection, short circuit protection and input and output protection ensure this robust design, and, thanks to its Molex Lite-Trap push in connectors, can be installed effortlessly.

With the Mantracourt ILA, gain and offset calibration is performed by dual 256-step non volatile digital potentiometers allowing fast, semi-automatic calibration via Mantracourt's proprietary Custom Programming Module and ILA Toolkit.

The ILA Toolkit software for Windows connects with the ILA via the programming module (ILA-PGMD). The toolkit allows the ILA to be configured and provides both manual calibration (and semi-automatic calibration). The ILA is available in the following standard sensitivities – 1 mV/V, 2 mV/V, 2.5 mV/V, 3 mV/V and 4.5 mV/V, cased or as an OEM version.
