Designed for general-purpose vibration
measurement, typically balance of plant (BOP) machinery such as compressors,
gearboxes, motors, pumps and fans·        
Industry standard 4 to 20 mA
loop-powered vibration sensor (vibration transmitter)·        
Quasi-static output signal (4 to 20 mA
proportional to 0 to 20, 0 to 25, or 0 to 50 mm/s) indicating “overall”
vibration·        
Typically connected to a machinery
monitoring system for protection applications and/or a control system such as a
DCS or PLC for monitoring and/or control applications·        
IP68 protection ratingCurrent output signal: 4 to 20 mA
proportional to 0 to 20, 0 to 25, or 0 to 50 mm/s.Frequency response: up to 1000 Hz.Temperature range:  −55 to 90°C.The PV685 piezoelectric velocity sensor
is a general-purpose industry standard 4 to 20 mA loop-powered vibration sensor
(vibration transmitter) with a piezoelectric sensing element, integrated
electronics and a current output. It is available with a sensitivity of 4 to 20
mA proportional to either 0 to 20, 0 to 25 or 0 to 50 mm/s.The PV685 is available as a sensor only
or fitted with an integral cable that is protected by a stainless-steel
overbraid. Sensor only versions allow one of a range of different cable
assemblies to be used to connect the sensor to the monitoring system, depending
on the application and environment.The PV685 is designed and manufactured
for use in harsh industrial environments.Features·
