A load cell transmitter is an essential component in measuring and converting the load cell’s weight or force signals into readable outputs. It plays a critical role in various industrial and laboratory applications, such as material testing, process control, and electronic scale systems. The DY610 load cell transmitter (digital load cell amplifier), which we’ll focus on here, uses a compression load cell to provide accurate measurements. Proper calibration of this transmitter is crucial for ensuring precise weight readings. Below is a step-by-step guide on how to calibrate the DY610 load cell transmitter to enhance its accuracy.

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.

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.

We covered how to calibrate the load cell and connect it to the load display in our previous blog. In the process of using the sensor, sometimes we need the standard analog signal of the sensor, so we need a transmitter to convert the mV signal of the load cell into standard industrial signals, such as 0-20mA, 4-20mA, 0-10V, etc. ATO load cell transmitter is the protagonist of our introduction, its output signal is 4~20mA.

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.
