The strain gauge amplifier is a high performance signal conditioner for single or multiple strain gauge bridge sensors such as load, force, pressure and torque.

The SGA A&D provides strain gauge signal conditioning for load cells and offers a wide bandwidth and a wide input signal range. The device can be powered from AC or DC supplies providing excitation for up to four x 350 Ohm strain gauge bridges.

The conditioned output signal can be selected from 0-20 mA, 4-20 mA, 0-10 V, 0-5 V, ±5 V or ±10 V.

Supplied in a waterproof IP67 NEMA4 bulkhead mountable case and is available with AC or DC power supply options. The strain gauge signal conditioning module is robust and fully CE compliant.

Q: Can the SGA be mounted on a DIN Rail?

A: Yes, the SGA can be mounted on a DIN Rail using a D4 base plate listed as an optional accessory for your SGA. Please contact us for more information.

Q: Does the SGA have shunt calibration?

A: The SGA has an onboard shunt calibration function. This shunts one arm of the connected load cell to produce a known change in the output which can be used for calibration or checking load cell integrity (or associated wiring).

Q: Does the SGA / LVDT lose its calibration if you switch it from 4-20 mA to 0-10 V?

A: Yes
