 Data sheet (119kb) |  |  | |||||||||||||
| Signal conditioning is required where the output of a transducer needs to be boosted or changed into a form suitable for the monitor or logging device which will be used. Our digital display units have a built-in monitor device in the form of the digital display as well as analogue output. Both E308 and E309 have high and low limits with voltage-free relay outputs. The E308 has a shunt calibration facility to enable calibration checks to be made. A very wide range of gain adjustment ensures that our amplifiers are compatible with the vast majority of LVDT and strain gauge sensors available from any manufacturer. Although they have a digital display, these units are entirely analogue and are configured using switches and potentiometers, there is no set-up software to learn. | |||||||||||||||
