Load Cell For Weight Measurement

What is a load cell? The load cell is a kind of sensor, which means a load cell can convert force into a measurable electrical signal. There are various load cell sensors types, such as hydraulic load cells and pneumatic load cells, one of the most common is the resistance strain type load cell, which is the main product of our TianGuang company.

Strain gauge load cells have the characteristics of wide adaptability, easy installation, and high precision. Except for some specific environments, strain gauge load cells are the first choice in the weighing industry. TianGuang load cells' capacity ranges from 5kg to 1000 Tons and accuracies from 0.02% to 0.5% full scale (Except for some customized products).

Type of High Precision Load Cell

Parallel Beam Load Cell

The product is adjusted at the four corners to ensure that it outputs consistently at all points in the specified load plane. suitable for packaging scales, platform scales, electronic belt scales, batching scales, etc.

Column Type Load Cell

Wide range, strong anti-overload capability. Widely used in pharmaceutical and chemical, coal metallurgy, electronic truck scales, railway scales, storage scales, tanks and other large tonnage measuring equipment.

Pancake Load Cell

Low height, good rigidity, high accuracy, strong anti-bias capacity. Widely used in belt scale, hopper scale, warehouse-scale, charging bucket, material mechanics testing machine, labor safety testing equipment, etc.

Shear Beam Load Cell

It can choose built-in amplifier,output 4~20mA or 0-5V analog signal.

Bellow Type Load Cell

Anti-eccentric load, aurora welding, good sealing performance, and can be used in tension and compression. It is suitable for the measurement and control of electronic scales, belt scales, hopper scales and other force values.

Micro Load Cell

Stainless steel material, small size. Suitable for force measurement with limited space. Commonly used in some fatigue tests, strength test,s or laboratory occasions.

Load Cell Working Principle Guidelines

The most common load cell is the resistance strain type, which is our company's product (TG sensor). The load cell changes its resistance when a load/force is applied to it. This change in resistance leads to a change in output voltage when an input voltage(usually 10V DC) is applied. Here is a load cell sensor diagram for your reference.

When we make sensors, we usually use 4 strain gauges (or even more for better accuracy) to form a Wheatstone bridge. When the sensor is not under force, the output is basically 0. When a load is applied to the sensor, the resistance of the strain gauge will change, and the change in resistance will cause a change in the output voltage. This change is relatively small, usually 0. -20mV, sometimes we will amplify it into a signal that is easier to measure, such as 0-5V or 0-10V.
