Transbridge Transducer Amplifier

Amplify output voltage signals

Transbridge (SYS-TBM4M) is a four-channel analog 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.

Features

Each channel contains a regulated 10-volt power supply (+5 and -5 volts 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.
