The CE620 444-620-000-111 Piezoelectric Vibration Acceleration Sensor is an industrial-grade IEPE (Integrated Electronic Piezoelectric) vibration monitoring device. This product is developed specifically for harsh industrial applications, and it finds widespread usage in the condition monitoring and protection systems of rotating machinery.
The 444-620-000-111 sensor integrates an electronic circuit, which can convert mechanical vibration signals into stable voltage output signals and connect to the monitoring system (such as the VM600 system) through standard interfaces.
This sensor employs IEPE technology and has the following features:
Built-in signal conditioning circuit
Outputs standard voltage signal (AC)
Adds DC bias voltage
Requires a constant current power supply for operation
