Isolation Amplifier

Operation principle

To measure voltage (Vp), the AV 100 series uses only well known electronic components, the main one being an isolation amplifier. The voltage to measure (Vp) is directly applied on the transducer primary connections through an internal resistor network and some components allowing the signal to feed an isolation amplifier.

An isolated signal is recovered and then conditioned in order to supply a current at the transducer output connections, which is an exact representation of the primary voltage.

Features:

• Any kind of signal, DC, AC, pulsed and complex can be measured
• Galvanic isolation between primary (high power) and secondary circuits (electronic circuit)
• Short dynamic response for a good frequency bandwidth
• Fast response time
• Small volume needed
