Supports temperature compensation(-30°C to+120°C)to eliminate the impact of ambient temperature on measurements.
Multi-scene adaptation
Measurement types:shaft vibration,shaft displacement,oil film thickness,bearing shell wear,shaft eccentricity,etc.
Compatible system:It can interface with EPRO MMS 3000/6000 series monitoring system,DCS or PLC,and supports Modbus,4-20 mA and other protocols.
Anti-interference design
Double-layer shielded cable and differential signal transmission technology are used to suppress electromagnetic interference(such as inverter harmonics and transient interference of welding machines).
Installation flexibility
Supports threaded or flange installation,with optional thread length(25 mm to 115 mm)to meet different space needs.
Typical application scenarios
Electricity Industry
Steam turbine and generator bearing vibration monitoring(alarm threshold≤50μm p-p).
