USB transmitter for load cells, 4 channels, acrylic box

The PhidgetBridge is the interface board needed to measure the output from a load cell. You can connect up to four load cells, strain gauges, or wheatstone bridge sensors. Mounting and calibration with load cell / weighing platform etc are included in the price.

PhidgetBridge lets you connect up to 4 un-amplified Wheatstone bridges, such as:

• strain gauges
• compression load cells
• pressure sensors/Barometers
• piezoresistive accelerometers
• Magnetoresistive sensors (Compasses)
• Supplied only via the USB

The data rate and gain values can be configured in software.
