Practical case study of pressure transmitters
What are the common reasons why the temperature measurement point on the DCS operation screen turns white? (1) The clamp safety barrier is not powered or faulty (2) The site is not wired or the wiring is wrong (3) The measured temperature is out of range There is a pressure transmitter, which i...Read more -
Daily maintenance of pressure transmitters
During the use of pressure transmitters, attention should be paid to the following situations: Do not use a voltage higher than 36V on the transmitter as it may cause damage. Do not use hard objects to touch the diaphragm of the transmitter, as it may damage the diaphragm. The tested medium shou...Read more -
The difference between sensors and pressure transmitters is …..
A: Nowadays, sensors are composed of two parts, namely sensitive components and conversion components. The sensitive component refers to the part of the sensor that can directly sense or respond to the measured part; The conversion element refers to the part of a sensor that converts the measured...Read more -
The difference between a pressure gauge and a pressure transmitter is。。。。。
A: Pressure gauges are usually directly installed in pipelines, using the internal expansion tube to sense pressure and driving the gear mechanism to rotate the pointer to achieve the effect of displaying the pressure value B: Pressure transmitters are generally used in industrial automati...Read more -
Common faults of pressure transmitters
When the pressure rises, the pressure transmitter cannot output: In this case, the pressure interface should be checked for air leakage or blockage. If it is confirmed that it is not, the wiring method should be checked. If the wiring is correct, the power supply should be checked again. If the ...Read more -
Common faults of pressure sensors
The transmitter has no output 1. 1: Check whether the power supply of the transmitter is reversed; Solution: Connect the power supply polarity correctly。 1.2: Measure the power supply of the transmitter to see if there is a 24V DC voltage; Solution: The power supply voltage supplied to the tr...Read more -
How to choose a temperature sensor
Human survival and social activities are closely related to temperature and humidity. With the realization of modernization, it is difficult to find an area that has nothing to do with temperature and humidity. Due to different application fields, the technical requirements for temperature and hu...Read more -
Application of Fire Pressure Switch
The working principle of the fire pressure sensor: under normal circumstances, the positive pressure blower sends air to the air shaft through the air duct, and the pressurized air is sent to the front room or stairwell of each floor through the shutters or air valves on each floor. When the vent...Read more -
air handling system
Available in various combinations, filters and regulators are a must for any machine. Consideration should also be given to the use of other devices that perform functions such as energy isolation, blocking, marking and lubrication. All pneumatic movements require clean, dry air with sufficient f...Read more -
The function of fire pressure sensor
Now people pay great attention to fire safety, and the country also has strict regulations on fire protection facilities. Now all kinds of fire-fighting supplies are becoming more and more advanced, and a lot of electronic technology has been applied. Next, the sensor expert network will introduc...Read more -
Fire pressure sensor
1. Working principle After the alarm valve is opened, the alarm pipeline is filled with water, and the pressure switch is connected to the electric contact after being subjected to the water pressure, and outputs the signal of opening the alarm valve and starting the water supply pump, and the el...Read more -
Common scenarios of pressure sensors
A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. A pressure sensor usually consists of a pressure sensitive element and a signal processing unit. According to different test ...Read more
