　　BK-4C-3T force sensor with transmitter 0-5V detailed description: Weighing sensor is a device that converts mass signals into measurable electrical signals for output. Its performance largely determines the accuracy and stability of electronic weighing systems, and is therefore known as the heart of weighing systems.

　　1、 Sensitivity selection

　　Usually, within the linear range of a weighing sensor, it is desirable to have higher sensitivity for better results. Because only when the sensitivity is high, the output signal value corresponding to the measured signal is relatively large, which is beneficial for signal processing. When the sensitivity is too high, the overload capacity of the sensor is low, which affects its service life. External noise unrelated to the measured object will also be amplified by the amplification system, affecting the measurement accuracy. Therefore, it is required to choose the appropriate sensitivity according to one's own requirements. For example, if it is ensured that there will be no overload during long-term use, a sensitivity of 1.5MV/V or above can be selected and weighed within 30% to 70% of the full range. If overload loads are frequently generated and dynamic impacts are likely to occur, it is necessary to choose a range that exceeds the overload force, reduce the sensitivity of the sensor, and improve the overload capacity. You can contact our technical support for overload selection. Our technical support will provide appropriate sensitivity and range according to your requirements.

　　2、 Stability selection

　　The ability of a sensor to maintain its performance unchanged after a period of use is called stability. The factors that affect the long-term stability of sensors, in addition to their own structure, are mainly the usage environment. Therefore, in order for sensors to have good stability, they must have strong environmental adaptability. Before selecting a sensor, it is necessary to investigate its usage environment and choose a suitable sensor based on the specific usage environment, or take appropriate measures to reduce the impact of the environment. At the same time, economic considerations need to be taken into account, as sensors used in special environments are more expensive than those used in general environments.

　　Environmental weighing sensors can cause the following effects:

　　1. The high temperature environment causes the coating material of the sensor to melt, the solder joints to open, and the internal stress of the elastomer to undergo structural changes. Choose a high-temperature sensor.

　　2. In highly corrosive environments such as humidity and acidity, the sensor may experience damage to its elastic body or short circuits. Choose anti-corrosion sensors, such as stainless steel sensors.

　　3. Outdoor dust and humidity can cause short circuits in sensors. Select moisture resistant sensor

　　4. The impact of electromagnetic fields on sensor output disorder signals. Generally, sensors have this function and provide shielded wires. If the impact is too significant, you can choose to use aluminum boxes to completely enclose and multi-layer shielded wires, as well as shielded wires with thicker shielding layers that are not easily broken down.

　　5. Special explosion-proof sensors must be selected for flammable and explosive environments. Choose explosion-proof sensors or intrinsic safety sensors.

　　The stability of sensors has quantitative indicators, and after exceeding the service life, they should be recalibrated before use to determine whether the performance of the sensor has changed. In some situations where sensors are required to be used for a long time and cannot be easily replaced or calibrated, the stability requirements for the selected sensors are more stringent, and they must be able to withstand long-term tests.
