VBOX Strain Gauge Amplifier

HomeVBOX Strain Gauge Amplifier

Racelogic’s Strain Gauge Amplifier (RLVBSGA02) comes with two channels and is user adjustable.

Each channel is DC isolated and designed for full bridge operation, but can be adapted for use in half bridge and quarter bridge applications.

The output range of each channel is ±9v with input signal gain adjustable from approximately 25 to 1000.

Wire connection to the amplifier is via screw terminal contacts for simple fitting.

  • DC isolated channels
  • 90dB typical CMRR
  • Adjustable gain from 25 to 1000
  • Dual channel

Wires can be run into the Strain Gauge Amplifier using the three mini cables glands. This allows the lid to be replaced, enabling secure connections to the internal screw terminals without leaving them or the scale and offset adjustment screws exposed.

The Strain Gauge Amplifier can be used in conjuction with full bridge, half bridge and quarter bridge circuits.

Full Bridge Circuit

When using the Strain Gauge Amplifier in conjunction with a full bridge load cell, no additional equipment is required. Simply connect the load cell to the Strain Gauge Amplifier as shown in the diagram below.

 

Half Bridge Circuit

When using the Strain Gauge Amplifier with a half bridge load cell, two additional resistors must be placed in the circuit. The resistors should be rated to the same value as the maximum resistance of the load cell’s internal resistors and must be placed as shown in the diagram below.

 

Quarter Bridge Circuit

When using the Strain Gauge Amplifier in conjunction with a quarter bridge load cell, three additional resistors must be placed in the circuit. These resistors should be rated to the same value as the maximum resistance of the load cell’s internal resistors and must be placed according to the diagram below.

  • Supply Voltage: 6v – 18vDC
  • CMRR: Typically 90 dB (minimum 77dB)
  • Bridge Supply Voltage: 5v ± 2mV
  • Gain: Adjustable from 25 to 1000
  • Output Range: ±9v
  • Frequency Bandwidth: DC to KHz

ENVIRONMENTAL AND PHYSICAL

  • Weight: Approx: 160g
  • Dimensions: 101mm x 50mm x 24.5mm
  • Operating temperature: 0°C to +70°C
  • Storage temperature: -40°C to +85°C
