Acceleration sensor/speed transducer/speed transmitter

Description

 AT3000 is our latest developed micro-transmitter with a small and exquisite appearance.  The integrated chassis vibration transmitter consists of piezoelectric sensing element with measurement, conversion, integral,  amplification, transmission and other major circuits, all the indicators accord with standards of “ISO2954-1975" and "  GB13824-1992".

AT3000 installed built-in precision integral circuit to provide speed output,  based on  Piezoelectric Acceleration Transducer. Compared with magneto-electric velocity transducer. It has lots of advantages, for example, it has wider response frequency range (2HZ-4000HZ), mechanical moving parts are not easy to   damage   (working life up to 7 years), lightweight, excellent dynamic performance and so forth. AT3000 provide 4-20mA current output, wiring fault-tolerant protection, with  excellent  stability  reliability  and  strong  anti-interference ability.
