Types and application environments of weighing transmitters

A weighing transmitter is an electronic device that converts the signal of a load cell (or through a weight transmitter) into a digital display of weight. The weighing transmitter can store, count and print weight data. It is usually used in industrial and agricultural production The integrated circuit chips used in the instruments designed by various weighing instrument manufacturers are different, but the basic functional modules are similar. The weighing display controller is generally It consists of the following modules: analog-to-digital conversion module, power supply module, central processing unit module, keyboard display module, communication module, printing, input and output modules, etc. The weighing transmitter is suitable for electronic batching scales, fixed value scales, sorting scales and other control occasions. It also has upper and lower limit alarms and peak maintenance functions. Load cells, weighing modules, weight transmitters, weighing transmitter tables, weighing application systems

A load cell is actually a signal output device that converts a mass signal into a measurable signal. The actual working environment of the sensor must be considered first. This is very important for the correct selection of the sensor. It is related to whether the sensor can work normally, and its Safety and service life, and even the reliability and safety of the entire weighing instrument.

weighing transmitterMainly used in various electronic scales, industrial control fields, online control, overload alarm installation, material testing machines and other fields, such as electronic truck scales, electronic platform scales, electronic forklifts, power axle scales, electronic hook scales, electronic pricing scales, electronic steel Scales, electronic rail scales, hopper scales, batching scales, filling scales, etc..

The weighing transmitter is divided into resistance strain type, capacitance type, inductance type, piezoelectric type, piezoelectric type, vibrating wire type, etc. Among them, the resistance strain type load cell is the most widely used. This article will use the cylindrical resistance strain type weighing The working principle of the load cell is introduced as an example. The working principle of the cylindrical load cell is shown in Figure 1. The resistance strain gauge is pasted on the elastic sensing element and forms a bridge. The strain value of the elastic body varies with the weight of the measured object The resistance value of the resistance strain gauge will change synchronously with the strain of the elastomer.
