to check the difference between sensor, transducer and transmitter, we must first check the meaning of each of them.
sensor: a sensor/device that detects or measures a physical property and records, displays, or otherwise responds to it.
transducer: it is a converter/device that converts the changes of a physical quantity such as pressure or brightness into an electrical signal and vice versa.
transmitter: a transmitter/set of equipment used to generate and transmit electromagnetic waves carrying messages or signals, especially radio or television waves.

transmitter literally means sender, in the world of communication, a transmitter is a device that sends radio waves through an antenna.

in the world of process control (industrial automation), a transmitter is a device that converts a signal produced by a sensor into an instrument signal that represents a parameter being measured and controlled.

depending on the model, the load cells have 4 or 6 wires with a wire shield. 6 wire types in addition to power +, power -, signal + and signal – terminals (ext+, ext-, sig+, sig-) have two other wires, sense + and sense – (sen+, sen-) or reference+ and reference- are.
the resistance of electric wires depends on factors such as temperature and length. considering this, it can be said that changes in temperature and length can cause changes in the voltage drop on the wire, which the 6-wire system allows to compensate for these changes.

an analog-to-digital converter (adc, a/d, or a-to-d) is a system that converts an analog signal, such as sound entering a microphone or light entering a digital camera, into a digital signal.

an adc converts a continuous-time, continuous-amplitude analog signal into a discrete-time, discrete-amplitude digital signal. adc is not capable of continuous conversion, so adc samples the input signal and after converting the sample to a digital value, moves to the next sampling.

wheatstone bridge is a special arrangement of four electrical resistances that is used to determine the unknown resistance.
the wheatstone bridge was invented by samuel hunter christie in 1833 and improved and popularized by sir charles watson in 1843. one of the early applications of paul whetstone was for soil analysis and comparison.

a strain gauge is a piece used to measure bending. this piece was invented in 1938 by edward e. simmons and arthur c. ruge.

it has happened in many cases that you have encountered this case during or after setting up the load cell that it seems that the load cell does not behave as you expected or does not show any response to force changes.

the question that will arise for an engineer is how should i ensure the health of the load cell used?

according to the knowledge and experience gained in this field, pars mega offers some simple solutions for load cell troubleshooting and at the end offers you a simple and very accurate proposal.

the accuracy of the signal to be measured has always been one of the basic challenges of electrical and electronic engineers. in this article, we are going to discuss the effect that earth has on the accuracy of the reading of the signal to be measured.
for this purpose, we have chosen a widely used signal, that is, the signal received from the load cell transducer, and the transmitter under test is the pm-lt01 transmitter.
