Product Details

The AC or DC Powered Strain Gauge Amplifier can provide excitation for up to 4 x 350 ohm strain gauge bridge sensors.  This high-performance signal conditioner is AC or DC powered and can be used with multiple strain gauge bridge sensors such as load, force, pressure and torque.

It offers a wide bandwidth and wide input signal range.  Plus, it has a very stable bridge excitation, selectable sensitivity, and high frequency filtering with user-selectable analogue outputs.

Conditioned output signal can be selected from 0-20mA, 4-20mA, 0-10V, 0-5V, ±5V or ±10V. Options include: Isolated DC supply, DIN rail mount and OEM module.

The robust AC or DC Powered Strain Gauge Amplifier SGA is supplied in a waterproof IP67 NEMA4 bulkhead mountable case with AC or DC power supply options. Robust and fully CE compliant this SGA can be used in most industrial environments.
