The ETH-401 is a dedicated bridge amplifier for BIOSEB transducers 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 ETH-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 IX-118.
Gain control on the ETH-401 is very straightforward. A programming resistor placed in the DIN-8 connector is used to definitively set the gain. BIOSEB transducers set the ETH-401 gain to the optimal value for a given measurement. However, this does not limit the ETH-401 to use with BIOSEB transducers. Most of non-BIOSEB transducers, can be set to work with the ETH-401.
The ETH-401 is an inherently very low offset device. This, together with the low offsets characteristic of bridge-style transducers and the high resolution of the IX-118 data acquisition system dramatically minimizes the need for offset control. The ETH-401 user experience is simplified as a result.
The ETH-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.
