What's the difference between a load cell and a pressure cell?

Sensors are widely used in our industrial area. At present, many enterprises pay more attention to the installation of sensors. At the same time, we must first have a certain understanding of the application of sensors. Sensors can detect mechanical quantities such as tension, tension, pressure, weight, torque, internal stress and strain.

Specific equipment includes metal strain gauges, pressure sensors, etc. It has become an indispensable core component in power equipment, construction machinery, various construction machinery and industrial automation systems. So what's the difference between a load cell and a load cell? Evergreen Bian Xiao will introduce it to you below.

What's the difference between a load cell and a pressure cell?

1. The load cell only measures the weight and only measures the direction of the gravity field. The weight is always greater than zero. If the container is placed under the load cell, it will not produce weight in the opposite direction. On the other hand, the force sensor can measure forward, backward, tension and pressure.

2. The load cell is produced in the factory and then calibrated on site. The force sensor is calibrated in the factory immediately after production, and it is necessary to ensure that the measured values of the sensor are the same after disassembly and installation. Therefore, the force sensor has a stronger structure than the weighing sensor to ensure the repeatability of the measured value under changing conditions and more information.

3. The standards of load cell and force cell are different. The load cell is usually a trade scale standard, while the force cell needs to conform to VDI2635 or ISO376 standard. Among these standards, repeatability is the most important factor.
