Measurement amplifiers offers multichannel capability

CAMBRIDGE, UK — The 9236 series of measurement amplifiers from Burster offers multichannel capability to process the standard output signal from strain gauge sensors.

These measurement amplifiers are used wherever the output signal from strain gauge sensors, such as load cells, pressure sensors or torque sensors, need to be converted into an amplified voltage signal and cannot be processed in its raw form.

Once the measurement signal has been conditioned by the amplifier, it can then be scaled and processed in a suitable controller unit. Typical applications include automated manufacturing systems and laboratory and field measurements, for example.

Users can select the input voltage range, making easy to connect strain gauge based sensors with sensitivities of 0.5 to 30mV/V. Output voltage can be set between 5 and 10 V.

With a high cut-off frequency of 1 kHz, the amplifier is also suitable for dynamic acquisition of rapidly varying measurements. A 15 to 30 V supply is required for the integrated device. In the multichannel version, up to four measuring channels can be implemented in one housing.

The standard model is designed for easy DIN rail mounting in an industrial environment, in a control cabinet or right next to the sensor. A single-channel IP 67 version is available for installation in a harsh environments outside the switchgear cabinet.

For integration in the user's application, the amplifier also comes in a single-board version, which can be built into the customer's own application-specific housing designs.

The measurement amplifier works with practically all strain gauge sensors supplied by burster, and can be calibrated to work with a specific sensor if required.
