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. These amplifiers are suitable for LVDT transducers.
Our S7 amplifiers are specifically designed to be installed close to the transducer so that the signal can be boosted as soon as possible. The S7 signal conditioning units are mounted in a die-cast aluminium housing and have a good level of environmental protection and screening from electrical noise.
A very wide range of gain adjustment ensures that our amplifiers are compatible with the vast majority of LVDT sensors available from any manufacturer.
