Industrial Precision Piezo Current Vibration Sensor Transducer 4-20ma for Measure Absolute Vibration Velocity
S31 and S38 integrated vibration transmitters are specialized and highly sophisticated designs based on acceleration sensors with precision integration circuits embedded inside.
Features: using piezoelectric crystal as the sensitive element, no intenal moving parts, no degradation and wear. Mechanical moving parts are not easy to damage strong anti-jamming ability frequency response range wide dynamic characteristcs excellent stainless steel housing laser welding sealing double shielding (isolaton)waterproof, dustproof, anti-oil range can be customized.
Application: Measurement of bearing box,shell or structure of the absolute /(relafive to the free surface) vibration suitable for industrial sites in a varietv of high-temperature environment
