Product Description:
The KSJB4 series quartz flexible accelerometer is specifically designed for high-temperature and vibration resistance. This advanced accelerometer offers exceptional repeatability, start-up performance, high-temperature resistance, and unparalleled reliability. It is suitable for both static and dynamic testing and serves as a standard vibration sensor.
The product adopts unique high temperature and seismic design, packaging technology and special circuit, the output current of the product is proportional to the measured acceleration, providing static and dynamic acceleration measurement, users can choose the appropriate sampling resistance through calculation, to achieve high precision output, and can be built in temperature sensor according to user needs, for offset and scale factor compensation. Reduce the impact of ambient temperature. We can replace QA650, T185, T160, JAE series products in place, but we use double torque structure, which is different from other companies' products, can make the accelerometer offset value and scale factor more stable, and have independent intellectual property rights. This product has been launched since 2010, and the number of deliveries has reached thousands. After years of application, it has become a mature product, especially for the measurement while drilling of oil drilling
Application fields: bridge, dam, oil well, coal mine inclination test, high-speed railway control, ship stability control.

Packing and Shipping:
Packaging and Shipping of Accelerometer Sensor
The Accelerometer Sensor is a precision instrument, so it must be handled and packaged with care. The proper packaging and shipping of the Accelerometer Sensor is essential to ensure that it is received in perfect working order.
Packaging
The Accelerometer Sensor must be packed to protect against damage during shipping. It should be placed in a static shielding bag, then surrounded with foam or similar cushioning material. The package should then be securely sealed and labeled as containing sensitive electronic equipment.
Shipping
The Accelerometer Sensor must be shipped using a reliable shipping carrier that provides tracking and insurance. The package must be clearly labeled with the sender and recipient's information. It is also recommended to have the package arrive with a "signature required" designation.
