Ultra low frequency two axis vibration acceleration sensor LD250

1） Overview:
The ultra-low frequency two axis vibration acceleration sensor LD250 is a variable capacitive acceleration sensor independently developed by our company. All its indicators meet the requirements proposed in ISO2954-1975 and GB13824-1992. This series of speed sensors adopts the principle of variable capacitance and is processed by an internal amplification circuit to output voltage. Starting at 0Hz, low power consumption, low noise, strong anti-interference ability, and high sensitivity. Suitable for low-power and low-speed vibration acquisition scenarios.
feature:
Embedded precision integrated circuit, low power consumption<4mA
Isolation floating, industrial site monitoring, strong anti-interference performance
Starting at 0Hz, suitable for low-speed applications

Application scope:
·Vibration detection of wind turbine tower frame and engine room vibration
·Vibration detection of cooling tower
·Vehicle dynamic control
·Platform stability leveling
