Tips: 4 digit display controller for load cells

A 4 digit display controller serves as a vital interface between load cells and users. It interprets the signals received from load cells, which measure force or weight, and presents this data in a user-friendly numerical format on a 4 digit display. Load cells convert mechanical force into electrical signals, but these signals require interpretation for meaningful human understanding.

The controller processes the analog signals from load cells, performs necessary conversions, and then showcases the resultant weight or force measurement on the digital display. It enhances usability by enabling users to conveniently read and interpret the weight or force values captured by the load cells. Additionally, such controllers often include features like calibration options, signal filtering, and display settings, ensuring accurate and calibrated readings for various applications, such as industrial scales, laboratory equipment, or other systems where precise weight measurement is critical.

This digital panel meter can provide accurate readings for load cells, force sensors and weighing sensors, suitable for measuring pressure, impact force, tension and weight.

This video shows the connection and setting of the digital display controller with S type load cell.

Digital Load Cell Display Controller

This is an intro video on ATO-CHB load cell display controller. It can display 5 digit readouts from -19999~99999 counts on its LED screen. Equipped with 4 buttons on the front panel, the indicator can work with load cells or force sensors for real-time logging, interlock, and alarming. Besides, it can produce two outputs for data comparison and it has a peak hold and valley function as well as net and gross weight display. It can handle an input range of 0 to ±25mV with 10V excitational power supply. In addition, there are 2 relay output alarms integrated in the indicator.

Panel display weight unit

Can the ATO-CHB2 panel display LBS and KGs?

ATO Responded

Hello, regarding the ATO-CHB2 panel you mentioned, it does not directly support the display of weight units on the panel. If you want to display in LBS, you need to calibrate the load cell in LBS.
