Four-wire and Two-wire system of Pressure transmitters
Most of the transmitters are installed on site, and their output signals are sent to the control room, and its power supply comes from the control room. There are usually two ways of signal transmission and power supply for the transmitter: (1) Four-wire system The power supply and the output sig...Read more -
Advantages of Digital Pressure Sensors
Pressure sensors are used in a variety of industrial applications ranging from hydraulics and pneumatics; water management, mobile hydraulics and off-road vehicles; pumps and compressors; air conditioning and refrigeration systems to plant engineering and automation. They play a key role in ensur...Read more -
Advantages of Digital Pressure Sensors
To get the highest possible pressure sensor accuracy, you need an output signal that is not easily damaged and has a very high resolution. 1. Reduce signal loss and interference The digital output signal is not subject to signal loss or interference like an analog signal, otherwise the intact sig...Read more -
Requirements of petroleum industry for pressure sensors
With the development of oil and gas industry, China’s oil and gas pipeline construction has made great progress. At present, pipeline transportation has become the main mode of oil and gas transportation. 60% of China’s existing oil and gas pipelines have been in operation for about 2...Read more -
Nonlinearity of Pressure Sensors
In addition to “temperature drift”, a high-precision sensor needs to investigate far more than that, and nonlinearity is one of the important performance indicators. Why should you be concerned about the non-linearity of pressure sensors? The pressure sensor is the core component of t...Read more -
What is the temperature drift of the pressure sensor
What is “warm drift”? Under the interference of external factors, the output of the sensor will usually change unnecessarily, which is independent of the input. This kind of change is called “temperature drift”, and the drift is mainly caused by the sensitivity element of ...Read more -
water pressure sensor
Water pressure sensor is a kind of pressure sensor commonly used in industrial practice. It is widely used in various industrial automation environments, water conservancy and hydropower engineering, transportation and construction equipment, production automation systems, aerospace technology, s...Read more -
Pressure hysteresis of a pressure sensor
As an important component of a pressure transmitter, the sensor has three important indicators that can determine whether a pressure transmitter can perform the measurement task well, they are: pressure hysteresis, pressure repeatability, and stability. Each transmitter must be tested and adjuste...Read more -
Urea sensor
The front part of the urea pressure sensor is used to detect the urea pressure, and the rear part is responsible for detecting the mixing pressure of urea and air in the mixing chamber. When the component fails: the urea consumption is abnormal, and the vehicle lights the fault light. When the fa...Read more -
How to Avoid Accuracy Errors
When choosing a pressure sensor, we have to consider its comprehensive accuracy, and what are the influences on the accuracy of the pressure sensor? In fact, there are many factors that cause the sensor error. Let us pay attention to the four errors that cannot be avoided when selecting a pressur...Read more -
How to use the level measurement of the pressure sensor?
One. An overview of the liquid level measurement method of the pressure sensor. The liquid level refers to the position of the liquid level in a sealed container or an open container. Through the measurement of the liquid level, the quantity of the material in the container can be known, so as to...Read more -
How to Choose a Pressure Sensor for Harsh Environments
Whether it’s hydraulically measuring the pressure of a control loop that provides feedback for pump pressure in an HVAC system, or measuring the pressure of coolant flow, heavy-duty sensors are capable of outputting high-level signals. Currently, design engineers are faced with the enormous...Read more
