Testimonials

Janice Carter, University of Cambridge

The person in WPI I deal with is Julian Williams and he has been very helpful in sorting out any problems we may have and finding items that we require. He is very pleasant to deal with and I have used WPI for the last 8 years and I am very happy with the service that they provide us.

Amplify output voltage signals

  • Use with many different types of resistive based transducers
  • WPI resistive force transducers plug in directly
  • Supports full resistive bridge or single ended operation
  • Output offset control
  • Four gain ranges from 1–1000 ×
  • Provides “excitation” voltage for resistive bridge transducers

Benefits

  • Provided with blank connectors to interface with any resistive bridge transducer
  • Bridge balance LEDs provide visual cue that unloaded transducers are at zero output state

Applications

  • Amplify signals from resistive strain gages and other resistive bridge configured transducers

TBM4M 4-Channel Transducer Amplifier

Transbridge (SYS-TBM4M) is a four-channel analogue transducer manifold, specifically designed to amplify output voltage signals from pressure, force, displacement, and temperature transducers as well as a wide variety of other signal sources. Analog output signals are available from each channel for input to a data acquisition system for digital signal processing in a computer. Each channel contains a regulated 10 V power supply (+5 and -5 V with respect to signal ground) to provide DC power to transducers, and a precision differential amplifier with selectable voltage amplification and variable position adjustment control.

Transducers

Transducers can be connected to Transbridge via any of the 8-pin connectors on the front panel. Four spare 8-pin DIN plugs are provided with each instrument to allow you to rewire cables of other manufacturers’ transducers and connect them to Transbridge. Each Transbridge channel may be used in either Full Bridge or the Half Bridge mode independently. For transducer types other than resistive bridges, such as active transistor circuits, magnetic, photocell or piezoelectric devices, the instrument’s differential amplifiers may still be used effectively for signal amplification in differential (full bridge) and single-ended (half bridge) modes. See WPI’s complete line of TRANSDUCERS for physiological measurements.
