How to Install a Load Cell?

Proper installation of the load cell is crucial for ensuring a stable and accurate weighing system. The following guide details the correct steps for installing a load cell.

Preparation Before Installing the Load Cell Sensor

Determine the Installation Location

Choose a flat, stable surface for installation to avoid vibration or tilting, ensuring the sensor can accurately measure weight.

The mounting surface must be clean and free of oil, adhesive film, and other impurities. The base should be stronger than the sensor itself to prevent deformation from impact, which could affect measurements.

If multiple load cells need to be installed, adjust the base to ensure all sensors are on the same horizontal plane. A level can be used for adjustment to ensure even load distribution.

Prepare Installation Tools

Prepare appropriate screws, nuts, washers, or brackets, or use the original installation tools provided with the load cell, depending on the sensor size and load requirements.

For high-capacity load cells, it is recommended to use lifting equipment for transport to avoid damage from impacts or drops.

Begin Installing Your Load Cell Sensor

Align the Load

Keep the load and the load cell's axis aligned to ensure even force distribution on the load cell.

Bolt Fixing

Use a calibrated torque wrench to tighten the bolts to the manufacturer's specified torque, avoiding overtightening or loosening.

For single ended beam load cell, only the sensing end needs to be fixed; the other load end should remain unsecured to allow for elastic deformation under load.

Connecting Cables and Power Supply

Connect the power and signal cables to the reading device (e.g., PLC, computer) according to the instruction manual. Ensure correct interface (e.g., analog output, digital output, or wireless interface) to avoid poor contact or short circuits.

Pay attention to power supply stability; it is recommended to use the sensor's rated voltage to avoid overvoltage damage.

Calibration and Adjustment

Zero-point calibration: Adjust the reading to zero under no-load conditions. Test the sensor response with objects of different weights to verify reading accuracy and stability.

Sensitivity Adjustment: Place an object of known weight to check if the output matches; adjust parameters if necessary. If there are large variations in ambient temperature, temperature compensation calibration is required.

Proper installation of the load cell sensor is crucial for maintaining accuracy, safety, long-term system stability, and extending system lifespan. The above is a detailed guide to the installation of load cells, which we hope will be helpful to you.

How to Choose a Liquid Level Sensor?

Choosing the right liquid level detection sensor depends on your application requirements, including the type of liquid being measured, the application environment, and accuracy standards.

Factors to Consider When Purchasing a Liquid Level Detection Sensor?

Define the Type of Liquid to be Measured

Water/Non-corrosive Liquids

For detecting common liquids in water tanks, reservoirs, and HVAC systems, float-type liquid level sensors are the first choice. These liquids are stable and do not react. Float-type liquid level sensors are also inexpensive and have a long lifespan, making them ideal for detecting common liquids.

Highly Corrosive/Hazardous Liquids

For some chemical liquids, strong acids, and alkalis, non-contact liquid level sensors should be prioritized. For example, ultrasonic liquid level detection sensors and radar liquid level sensors can accurately measure liquid level data without direct contact with the liquid. 

The GRLM-70 series radar level meter is a good choice, with a measurement range of up to 40 meters and 10 models available for different scenarios.

Liquids containing foam, sediment, or high viscosity can interfere with certain sensing technologies. Radar waves can penetrate foam and only reflect off the liquid, making radar level sensors ideal for non-contact measurement in foamy and heavy steam environments. Capacitive level sensors can measure viscous liquids non-contactly or via probes, unaffected by sediment buildup.

Application Environment

For applications in extreme weather or harsh environments, sensors with high protection ratings and strong resistance to environmental interference should be selected.

Accuracy

Basic level detection: Float switches or fiber optic level sensors are usually sufficient.

Continuous level measurement: Ultrasonic, radar, capacitive, or pressure level sensors provide real-time level data.

High-precision applications: Sensors with minimal error range and long-term stable performance are required.

In summary, when selecting a level sensor, the type of liquid being measured, the application environment, and the required accuracy should be fully considered to ensure optimal matching.

What is a Load Cell?

A load cell that converts the weight (force) signal applied externally into a measurable electrical signal (such as voltage, current, or digital signal). It is a core electronic component of electronic scales, industrial weighing systems, and intelligent logistics systems.

How Does the Load Cell Work?

A load cell primarily consists of elastic elements, such as springs or beams, to withstand external forces, strain gauge sensing elements, signal processing circuits, and signal output devices, including displays or data interfaces.

When an external object is placed on the sensor, it causes deformation (compression or tension) of the elastic element inside the sensor. This deformation results in a slight change in resistance, which in turn changes the output voltage of the bridge circuit. This voltage signal is then amplified and converted into a digital signal, ultimately mapped to a weight value.
