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.
The E725 amplifier unit additionally has a serial output ａnd limit trips with optional relays. Features such as auto-zero ａnd MAX, MIN ａnd TIR store are features which are also available with most versions of this unit.
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. |
