The difference between a pressure sensor, a pressure relay, and a pressure switch
The pressure sensor is composed of a varistor and a conversion circuit, which uses the pressure of the measured medium to act on the varistor to produce a small change in current or voltage output. Sensors often need to be used in conjunction with external amplification circuits to complete proce...Read more -
Selection and installation of pressure switch for injection molding machine
Pressure sensors can be installed in the nozzle, hot runner system, cold runner system, and mold cavity of injection molding machines. They can measure the plastic pressure between the nozzle and the mold cavity during the injection molding, filling, holding, and cooling processes. This data can ...Read more -
Pressure sensor precautions
Firstly, let’s understand the structure and function of conventional pressure transmitters. A pressure transmitter is mainly composed of three parts: a pressure sensor, a measurement conversion circuit, and a process connection component. Its function is to convert physical pressure paramet...Read more -
Selection of pressure sensors
1. How to select a pressure transmitter? Firstly, it is necessary to confirm what kind of pressure to measure Firstly, determine the maximum value of the measured pressure in the system. Generally, it is necessary to choose a transmitter with a pressure range that is about 1.5 times larger than t...Read more -
Precautions for transmitter installation
Pressure transmitter 1. Pressure and negative pressure measuring devices should not be installed in curved, corner, dead corner, or vortex shaped areas of the pipeline, as they are installed in the straight direction of the flow beam, which can cause distortion of the static pressure head. When i...Read more -
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
