The PV685 440-685-000-211 is a piezoelectric velocity sensor from Meggitt Vibro-Meter, primarily used for machinery monitoring and protection in harsh industrial environments. The PV685 is essentially a 4 to 20 mA loop-powered vibration sensor (vibration transmitter) that outputs vibration signals via a current loop. Its output characteristics range from 4 to 20 mA, corresponding to vibration ranges of 0 to 20 mm/s, 0 to 25 mm/s, or 0 to 50 mm/s, respectively. The PV685 is available as a sensor-only version or as an integrated cable version with stainless steel braided shielding. For the sensor-only version, users can select from a variety of cable assemblies to connect the sensor to the monitoring system based on specific application and environmental requirements.

FAQ
1. What power supply does the PV685 require?
——10 to 30 VDC.
2. What is the difference between the PV660 and PV685?
——The PV660 outputs a voltage signal consisting of AC voltage plus DC offset (mV/mm/s) and is essentially a vibration sensor; the PV685 outputs a 4–20 mA current signal and is essentially a vibration transmitter. The PV660 has a frequency response up to 7000 Hz (±3 dB), with a wider high-frequency range, making it more suitable for mechanical diagnostics; the PV685 has a frequency response of 3–1000 Hz (±10%), with a narrower bandwidth, and is geared toward condition monitoring and protection.
