DESCRIPTION
The PPT-380 Eddy current proximity probes are used for non-contact measurement of shaft vibration and position. The sensor is designed with integrated linearization electronic in order to ensure
excellent linearity and active temperature compensation. The built-in oscillator tuned above 750kHz
ensures measurement with minimal magnetic run out effect.
The PPT-380 can be used either for measurement between 0.2mm and 2.2mm or 0.2mm and
4.2mm. The voltage output is directly proportional to the measured distance between the metallic
target and the sensor tip. The sensor can be powered either with -24V or +24V depending on the
configuration or ordering code.
The embedded sensor head is resistant to shock. The sealed body is resistant to oil and water on
both sides of the sensor.
Built-in Modbus interface provides time based calculated values such as pk-pk, mean, minimum,
maximum and temperature. The sensor can be operated in two modes: digital or analogue. The digital operating mode provides the calculated values via modbus interface and the analogue operating
mode provides the analogue output for commissioning or raw signal analysis.
Optional configuration kit (software, cable and USB adapter) allows to setup the measuring range,
the power supply type (+24V or –24V) and the target material, to perform on-site recalibration, to
select the operating mode and to visualise trending values.
