Pressure sensors are one of the most popular and almost indispensable types of devices in measuring, monitoring and controlling pressure values, helping to ensure the safe operation of pipes or equipment. . And wiring the pressure sensor is extremely important during installation, helping to ensure the sensors operate properly and ensure their inherent functionality. In this article, Makgil Vietnam would like to send readers the necessary information about how to wire pressure sensors, including three types: 2-wire type, 3-wire type and 4-wire type. <\/p>\n

Learn about pressure sensors<\/strong><\/h2>\n

Before going into details about how to wire pressure sensors, let’s briefly learn what pressure sensors are and their operating principles. Pressure sensor<\/a> (also known by many other names such as pressure sensor, pressure sensor, pressure transducer, pressure sensor, pressure sensor,…) – has the English name Pressure Sensor or Pressure Transmitter, is an electromechanical device used for the purpose of measuring, monitoring and checking pressure in systems, equipment, and pipes. The pressure sensor receives the pressure value through a mechanical transducer, then converts the pressure signal to an electrical signal and transmits the electrical signal to the display device, warning device or control device. control, PLC via electric cable. The output signal of a pressure sensor is usually mV signal (0~5mV, 0~10mV), voltage signal (0~5V DC, 0~10V DC,…) or analog signal (4-20mA, 0 -20mA\u2026). <\/p>\n

<\/span>How to wire a 2-wire pressure sensor<\/strong><\/h2>\n

2-wire pressure sensors are the most used design of the three types, they use the least amount of wire but have very little signal interference, while also keeping good isolation for other connected devices. with it. For 2-wire pressure sensors, the connection is slightly different from the other two 3-wire or 4-wire types, because the power wire and signal wire are common on 2 wires. In case the receiving device has a loop source on the 2 signal wires, the sensor will work well. However, if the receiving device does not have a loop source, we must connect an additional 24V or 12V source in series to detect the sensor. The new variable works. To put it more simply, when connecting a 2-wire pressure sensor, it can be divided into 2 cases: <\/p>\n

<\/span>Wiring the pressure sensor using active power<\/strong><\/h3>\n

The 4-20mA input signal of the PLC is capable of generating enough current so that the 4-20mA pressure sensor can transmit the signal to the PLC directly without the need for any other device. <\/p>\n

When making connections, like the picture above, we follow the principle that the sensor’s (+) pole is connected to the inverter’s (+) pole, and the sensor’s (-) pole is connected to the (-) pole. of the inverter, then power the pressure sensor. Making the connection is relatively simple. <\/p>\n

<\/span>Wiring the pressure sensor using passive power<\/strong><\/h3>\n

4-20mA Input signals from devices such as PLCs, inverters, display units, etc. are not capable of generating power. When we use the VOM meter to measure the input pins of these devices, there is no voltage, and then we are forced to use an external 24V DC power supply to transmit the signal from the pressure sensor. about PLC or other devices. <\/p>\n

When making the connection, we will make a loop between the pressure sensor, analog input signal and 24VDC output. Specifically, the positive (+) source of the 24V source will connect to the positive leg of the pressure sensor. The negative pin of the sensor is also the signal output pin that will connect to the positive input signal pin on the inverter. And the last job is to connect the input signal negative pin and the 24V source negative pin together. <\/p>\n

For the 3-wire pressure sensor, there is 1 power supply wire for the sensor to operate, 1 signal wire output from the sensor, and the remaining wire is the common ground wire between the power supply and the signal. When making the connection, the (+) 24V DC source is connected to the power supply wire for the sensor to operate, while the (-) 24V DC source is connected to the common ground on the sensor, which is also the (-) input. ) of the signal on the receiving device. Finally, the signal output wire of the pressure sensor is connected to the (+) terminal on the receiving device. <\/p>\n

<\/span>How to wire a 4-wire pressure sensor<\/strong><\/h2>\n

It can be said that connecting a 4-wire pressure sensor is the easiest of the three types of pressure sensors. Normally, a pressure sensor will have 02 signal wires coming from the sensor and 02 power wires supplying the sensor to operate. When making the connection, we only need to connect 02 sensor power wires to the 24V DC power source, and at the same time connect 02 signal wires to send to the signal receiving device and that’s it. <\/p>\n

4-wire pressure sensors are often rarely used because although they are easy to connect, with a 4-wire design, more wires are needed, and their stability is not high. Above is the necessary information in 2-wire, 3-wire and 4-wire wiring. We hope to help customers in selecting, installing and using sensors for optimal efficiency. best. <\/p>\n
