This Pre-Amp can be used in case the signal to noise ratio is insufficient.

Our new Ultrasonic Pre ľAmplifier incorporates the latest technology current feedback operational amplifier.

A Pre-amp is useful when due to material attenuation a large gain is required. In that case the long coax cable between the transducer and instrument will pick up Electro Magnetic Interference.

For these applications this Pre-Amp can help minimize the noise because it can be placed close to the transducer and thus effectively shorten the sensitive part of the coax cable.
