Brief Introduction
YD30 series integrated acceleration transducer is an integrated transducer that processing
acceleration sensitive elements on a polycrystalline silicon by micro-machine with conversion,
measurement and amplifier circuit. It can measure the acceleration of direct current that up to
2.5KHz within ±1g~±18g. It has excellent stability, reliability and strong anti-jamming capability.
As the common acceleration transducer need to calibrate on the standard vibration table, brings
lots of inconvenience to the users. The integrated acceleration transducer is much better than that.
With the use of advanced microelectronic processing technology and capacitance measuring principle,
it can obtain excellent low frequency responses, adjust the transducer by gravity acceleration g.
Its built-in self-checking system can easily check itself normal or not.
Range of Application
1. Equipment vibration measurement: YD30 series integrated acceleration transducer is widely used
in various industries equipments working condition monitoring. The vibration value when the device
is running is an important index for measuring the equipments running normal or not. The transducer
can measure the vibration value from direct current to 2KHz, the output signal will give an accurate
visual instructions for equipments’ amplitude by filtering and detection.
2. Impact measurement: widely used in automobile airbag and seat belts system. Thetransducer will
be impact when a crash happens,then it will output a pulse signal that in proportion to the impact
acceleration within 1 ms, when the impact acceleration reaches acertain value, the signal will make
the airbag outbreak or lock the seat belt to protect the people in the automobile.
3. Dip Angle measurement: When the transducer is placed gradient, the output value of transducer
is the component of gravity acceleration on the transducer’s gauging spindle, it means there is
anti-sine functional relation between output and slant angle, when the slant angle is small,
it is linear relationship approximately.
Working Principle
YD30 series integrated acceleration transducer is based on capacitive measurement principle to
measure acceleration.
