In current society there are many technological products that measure the amount of force, such as measuring pressure, tension, gravity and so on. A load cell, as the name suggests, is an instrument used to measure the gravity of an object. So do you know what a load cell is? And how does it measure the amount of force? ATO will provide you with detailed information about load cells. Please take a look in the followings.

A load cell, also known as a load or force transducer, is a sensor that measures applied forces. Load cells are capable of measuring both tension (force required to pull something) and compression (force required to push something). In order to measure these forces, the sensor creates an electrical output that changes depending on the amount of resistance being applied.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. We covered How to use PLC to monitor the data of load cell transmitter in our previous blog. Today we'll show you how to use HMI to display the data of load cell in real time.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are strain gauges, pneumatic, and hydraulic.

Digital load cell amplifiers are also called weighing transmitters. It can convert physical quantities into electrical signals, and convert the sensors outputting millivolt signals into standard DC signals through isolation and amplification. It usually adopts SMT process and is designed and manufactured for resistance strain signal sensors in industrial processes, and is suitable for load cells of different specifications.

The function of the weighing sensor can be shown only when the weighing sensor is equipped with a good weighing display instrument. We are going to introduce the wiring and calibration of ATA-DDC5-CHB universal weighing instrument.

A load cell is actually a device that converts a mass signal into measurable electrical output. ATO has introduced how to convert the m V model output by the pressure sensor into a 4-20mA standard analog signal. But in the industrial control process, digital signals are also extremely important, so this time ATO will explain the RS485 interface function ( Modbus RTU protocol ) of the load cell transmitter.

ATO 5 Digit Display Controller offers simple calibration and configuration with options for additional outputs such as 4-20 mA/ 0-10 V analogue outputs and communications ports for connection to PC's, PLC's printers and remote displays . It is designed for cooperating with load cells, force sensors and weighing sensors.

In our load cell product pages, when we introducing the load cells, we often say that you can buy a transmitter/amplifier with a customized output signal (0-5V, 0-10V, 4-20mA) to output standard signal to PLC, DCS and other control systems. Then someone will ask us how to connect load cell to plc. Now today we will explain the connection methods of load cell in details. When forming the weighing and batching control system with PLC, there are four connection methods for load cell.

Installation quality of load cells is decided by horizontal and vertical placement and height adjustment. In many use scenarios of electronic weighing instruments, it is observed that some weighing instruments are not bought from one professional manufacturer but from different manufacturers. Due to a lack of overall consideration, these weighing instruments might easily encounter different problems, including installation process, requirements of bolts and place limiting stopper.

Pancake load cell is also known as low profile load cell, because it has a low profile design and it looks like a pancake. On the other hand, pancake load cell can bear both tension and compression force. So it is also a tension and compression load cell that is widely used for platform scale, truck scale, rail weighbridge and tension tester.

The load cell has a certain overload capacity, but it shall still be prevented from overloading in installation. It should be notified that even a short-term overload can still cause permanent damage to the sensor. During the installation, a pad with the same height of the sensor could be firstly used instead if necessary, then replace the pad with the sensor. In normal operation, the sensor should generally be equipped with mechanical structure for overload protection. If the sensor is fixed with screws, the screw should have a certain fastening torque and screwing thread depth. Generally, high strength screws should be used.

ATO load cells have low capacity and high capacity, high accuracy, good output symmetry and high eccentric load resistant. Load cells can be applied for batching scale, crane scales, rail weighbridge, hopper weigher, button tester, force gauge and other special weighing instruments. Here is an ATO load cell price list for your reference. For more products information, please check the directory of load cells.

Load cell is based on the principle that resistance changes when the resistance strain gauge pasting on the surface of elastomer is forced deformation. Load cell converts the change of resistance to mV signal so as to complete the process of converting external force into electrical signal. According to its principle and structure, the fault of strain gauge load cell is often caused by some human or natural factors.

The calibration of load cell and digital display controller is mainly to confirm the weighing signal of zero point and full range of the load cell. That is to say, telling the digital display controller what are zero weight signal and full range weight signal received from the load cell. In this way, the digital display controller will display the value according to the detected weight, or export the matching weight signal to the PLC/DCS control system.
