During the epidemic, Huoshenshan Hospital, which rose from the ground within 10 days, made foreign netizens exclaim miracles. This is a life-and-death contest against the epidemic, and it is also a speed that Chinese are proud of. Behind the "China Speed", advanced construction equipment is indispensable, and the high efficiency of construction cranes is particularly important: first the plates are spliced into a container of about 2.5 meters, and then the container is built into two floors with a crane, so as to create the skeleton of the hospital.
Cranes play an important role in many construction sites because they are less affected by the terrain, convenient and fast, and have a large transportation volume. However, overturning caused by heavy loads or uneven ground often occurs. In order to reduce this risk and ensure the safety of the crane operation process, tilt sensors are usually used to detect the state of the crane boom and car body, so as to adjust the car body to a balanced state.
On the other hand, when the lifting angle of the crane boom is too large, the weight distribution of the whole system in the horizontal direction will be too concentrated, which greatly reduces the horizontal stability of the crane. In order to prevent the lifting angle of the boom from being too large, it needs to be limited by an inclination sensor to avoid dangerous situations caused by other unstable factors.
With a high degree of protection of IP68 and IP69K, the BekafoF99 inclination sensor can cope with harsh environments such as heat, dust, constant vibration and shock. to ensure accurate measurements, even under harsh conditions. The innovative split mounting concept makes the F99 series extremely robust: The sturdy metal mounting bracket protects the sensor modules from vibrations and can be replaced quickly and easily if required. Once installed, the bracket can remain in place without the need for readjustment or calibration.
The integrated F99 series inclination sensors are durable in a corrosion-resistant aluminum housing and offer an inclination measurement range from 0 to 360° with an accuracy of 0.15°. The sensors output independent single- and dual-axis signals and are available in a variety of operating configuration modes such as CANopen, SAEJ1939 or setting with teach-in buttons. Customers can customize the measurement angle and output switching point, and feedback the angle and switching signal in real time.

Important features of our sensors
On the linear scale of our sensors, the higher the sensitivity, the better. Because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and the external noise that is not related to the measurement is also simple.

Static and dynamic characteristics of sensors – we are blessed
1. Static characteristics of the sensor
The static characteristics of a sensor are related to the static input signal, the output and input of the sensor. Since the input and output are moment-independent at this point, the connection between them (i.e., the static properties of the sensor) can be used in an algebraic equation without time variables.
