| WPI-401 Four-Channel Transducer Interface |
|||||||||||||||||||||||||||||||||||||
 The WPI-401 is a dedicated bridge amplifier that provides four channels of excitation power, gain, and noise filtration. It exhibits low system noise and offset, making it suitable for use with high resolution data acquisition systems. The WPI-401 is an ideal solution for interfacing low bandwidth transducers, such as those used to measure force, blood pressure and displacement to data acquisition systems such as the WPI-118.Gain control on the WPI-401 is very straightforward. A programming resistor in the DIN-8 connector is used to set the gain. WPI transducers set the WPI-401 gain to the optimal value for a given measurement. However, this does not limit the WPI-401 to use with WPI transducers. Many non-WPI transducers, can be modified to work with the WPI-401. The WPI-401 is an inherently low-offset device. This, together with the low offsets characteristic of bridge-style transducers and the high resolution of the WPI-118 data acquisition system dramatically minimizes the need for offset control. The WPI-401 user experience is simplified as a result. The WPI-401 is packaged in a low profile aluminum enclosure that provides both durability and increased noise immunity. The device has a small foot print and multiple units are easily stacked to save bench space. |
