SHANGHAI CHENZHU INSTRUMENT CO., LTD., signal isolator suppliers, is a very established provider that specialises in automation and safety. We have over 24 years of experience in the design and manufacture of intrinsic barrier, signal conditioner, surge protection device, safety relay, signal conditioning isolation, digital signal isolator, power transmitter and intrinsically safe temperature transmitter. Our products and solutions cover many areas--from process automation safety to factory automation.
Signal conditioner is used in industrial process control systems. It connects industrial field instruments and control systems to complete the function of signal matching and conversion. Through reliable isolation technology, it resists various interference attacks and ensures the stability of the system and instruments in a complex electromagnetic environment. The Signal conditioner of Chenzhu using special design achieves anti-interference among power supply, input, and output. At the same time, it has a strong EMC performance that can work normally even under strong interference.
So far, our signal conditioner, as a member of the whole safety automation system, has been applied to tens of thousands of industrial sites. And the stability of the control system escort, possessing the most complete models, has reached the international level.

What is the difference between 2-wire transmitter, 3-wire transmitter and 4-wire transmitter?
2-wire transmitter
2-wire transmitters are the simplest and most economical way to used them in the industrial field. The zero-end current is 4mA, which is sufficient to drive the transmitter's internal circuitry, while the current at 4-20mA represents the range of process transmissions measured.
3-wire transmitter
Some transmitter require more power than the signal loop can supply their internal circuity. The three-wire current output can share a ground wire with the power supply, saving a wire.
4-wire transmitter
Four-wire transmitters have their own internal power supply, and they do not need to be connected to a DC power supply. It has two power cords and two current output lines. The output of a 4-wire transmitter is usually a current signal.
We provide kinds of isolated signal conditioner, include pt100 signal conditioner, universal signal conditioner, 24v to 5v signal converter, 5v to 24v plc signal converter and so on.
