What is the difference between integral preamp sensor and general type sensor?

Brief:General type sensor: the sensor is generally composed of a shell, protective film, piezoelectric element, damping block, connecting wire and high frequency socket. There is no signal preamplifier circuit inside. When the sensor is used, it needs to use a preamplifier to amplify the voltage signal converted by the sensor and then transmit it for use. Integral preamp sensor: this sensor including an extra preamp circuit than the general type sensor.

   

General type sensor: the sensor is generally composed of a shell, protective film, piezoelectric element, damping block, connecting wire and high frequency socket. There is no signal preamplifier circuit inside. When the sensor is used, it needs to use a preamplifier to amplify the voltage signal converted by the sensor and then transmit it for use.

Integral preamp sensor: this sensor including an extra preamp circuit than the general type sensor, so no more preamplifier is needed when use this kind of sensor, it can reduce the cable connection work.
