1. What is a pressure sensor?
A pressure sensor is a device that can convert a pressure signal into an electrical signal and is widely used in various industrial automatic control environments. It usually consists of a pressure sensitive element and a signal processing unit, which can sense the pressure signal and convert it into a usable output electrical signal according to a certain rule.
Definition and function
The basic concept of a pressure sensor is to convert a pressure signal into an electrical signal for subsequent signal processing and control. The working principle of a pressure sensor is mainly based on physical phenomena such as piezoelectric effect, strain effect and capacitance effect. The piezoelectric effect refers to the fact that certain materials generate electric charge when subjected to pressure; the strain effect refers to the deformation of the material when subjected to pressure, thereby changing the resistance value; the capacitance effect refers to the change in capacitance value caused by pressure change.
Classification
According to the working principle and structural characteristics, pressure sensors can be divided into the following categories:
Piezoresistive pressure sensor: based on the strain effect, usually made of semiconductor materials.
Piezoelectric pressure sensor: based on the piezoelectric effect, usually made of crystal or ceramic materials.
Capacitive pressure sensor: based on the capacitance effect, composed of two conductors and an insulating medium.
Fiber optic pressure sensor: uses the light transmission characteristics of optical fiber to convert pressure signals into optical signals. -
2. Application field
Sensor: Mainly used for industrial process control and monitoring, equipment control and monitoring in the fields of automobiles, machinery, electronics, medical equipment, aerospace, etc., as well as environmental monitoring and weather forecasting.
Transducers: Mainly used in exploration and production processes in the fields of ocean, petroleum, aviation, energy, etc., engineering measurement and control fields (such as monitoring and control of structures such as buildings, bridges and tunnels), scientific research fields (such as physics, chemistry, biology, etc.), and music and art fields (such as electronic musical instruments and sound amplifiers). -
3. What is the difference between a pressure sensor and a pressure transmitter?
The main differences between pressure sensors and pressure transmitters are working principles, signal processing, and application scenarios.
Working principle
Pressure sensor: The main function of a pressure sensor is to convert a pressure signal into an electrical signal. Common pressure sensors include resistance strain gauges, ceramic pressure sensors, and diffused silicon pressure sensors. These sensors convert pressure changes into electrical signal outputs through piezoresistive or piezoelectric effects.
Pressure transmitter: The pressure transmitter adds a signal conditioning module to the pressure sensor, which can further amplify, convert, and output an electrical signal proportional to the pressure. Transmitters usually have higher accuracy and stability and are suitable for a wider range of pressures.
Signal processing
Pressure sensor: Usually outputs signals directly related to pressure, such as resistance values, capacitance values, etc., which require further processing to obtain useful information.
Pressure transmitter: Directly outputs standard electrical signals, which are easy to process and interpret in the control system and are suitable for various automated control systems.
Application scenarios
Pressure sensor: Widely used in scenarios where real-time pressure monitoring is required, such as industrial automation, medical equipment, etc. Due to its high accuracy and stability, it is also suitable for laboratories, instrumentation, and precision measurement fields.
Pressure transmitter: widely used in process control, energy management and other fields, such as petroleum, chemical, water treatment and other industries. Due to its integrated, intelligent and miniaturized characteristics, it is also suitable for various harsh industrial environments.
In summary, pressure sensors and pressure transmitters have significant differences in principles, signal processing and application scenarios. Users should choose suitable products according to specific needs.

The main difference between sensors and actuators lies in their functions, design principles and application scenarios.
Function and design principle
Sensor: A sensor is a device that converts various physical quantities (such as temperature, pressure, light intensity, etc.) into easy-to-process electrical signals. Its main function is to detect and collect physical quantities in the environment, and convert these physical quantities into electrical signal output for further processing and analysis.
Actuator: An actuator is a device that converts electrical signals, air pressure, hydraulic pressure and other energies into physical motion. Its main function is to perform corresponding action control according to the received electrical signal, such as controlling the movement of the robot, adjusting the cutting of the machine tool, etc.
Application scenarios
Sensors: Sensors are usually used in areas that require monitoring environmental information, controlling automation equipment, adjusting motion control systems, such as smart homes, aircraft, robots, etc.
Actuators: Actuators are used to adjust control systems, convert energy, complete mechanical work, etc., such as hydraulic pumps driven by electric motors, pneumatic control valves, etc.
