Signal Conditioner

Signal Conditioner

Universal signal conditioner is used in industrial process control systems. Isolated signal conditionerconnects industrial field instruments and control systems to complete the function of signal matching and conversion. Through reliable isolation technology, the signal conditioning equipment resists various interference attacks and ensures the stability of the system and instruments in a complex electromagnetic environment. The isolated pt 100 signal conditioner of Chenzhu using special design achieves anti-interference among power supply, input, and output. At the same time, the signal conditioning isolationmodule/unit has a strong EMC performance that can work normally even under strong interference.

So far, our signal conditioning amplifier for electronics, 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. As one of the most professional signal isolator suppliers, Chenzhu promises to provide you good transducer signal conditioning and services! Different types of signal conditioning system for circuits can be offered by us, whether it's based on RTD loop powered digital isolator or DC Pt100 signal splitter with 4-20mA output current. If you want to know the price of our 5v to 24v PLC signal converter, please contact us as soon as possible. Related sensors and signal conditioning pdf files are also available for you to refer to.

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.

FAQ of Signal Isolators

Q

How to distinguish between the active and passive signals?

A

According to whether the signal acquisition loop needs an external power supply,

Active signal：In the 4~20mA signal acquisition loop, the signal generating end has its own voltage drive and no external power supply equipment is needed. This 4~20mA is an active signal. Generally, 4-wire transmitter and 3-wire transmitter output active signals.

Passive signal：In the 4~20mA signal acquisition loop, the signal generating end does not have its own voltage drive and external power supply equipment is needed. This 4~20mA is a passive signal. Generally, a 2 wire temperature transmitter outputs passive signals.

Method of judging whether the external power supply is needed in the signal acquisition loop：

Disconnect the signal acquisition loop, and connect a voltmeter to the two lines of the field device (voltage transmitter). If there is voltage, it means the field device outputs active signals. If there is no voltage, it means the field device outputs passive signals.
