A pressure sensor is a sensor that converts the input mechanical pressure in a gas or liquid into an electrical output signal. Pressure sensors are also called Pressure transmitters or Pressure Transducers. Because most users do not strictly distinguish them. In fact, they are different.
Pressure sensors generally refer to sensitive elements that convert changing pressure signals into corresponding changing resistance signals or capacitance signals. Such as: piezoresistive elements, pressure-capacitive elements, etc.
Pressure transmitters generally refer to a complete circuit unit for measuring pressure composed of a pressure-sensitive element and a conditioning circuit. Generally, they can directly output a standard voltage signal or current signal that is linearly related to the pressure, which can be directly collected by instruments, PLCs, acquisition cards and other equipment.
Types of Industrial Pressure Sensors
Although there are many measurement principles for pressure sensors, there are 4 types of industrial pressure transmitters commonly used on the market. They are differentiated based on the type of pressure.
Gauge Pressure Transmitters – They are compact, general-purpose devices designed for use in almost all industrial applications, with the primary purpose of measuring pressure ranges.
Hydrostatic Transmitter – Often called a liquid level transmitter due to its operating principle and ability to measure liquid level. Hydrostatic pressure sensors work on the principle that the pressure value increases with depth. These devices are submersible and can be used with liquids and gases.
Absolute Pressure Transmitter – Used where gas or liquid pressure is isolated from changes in atmospheric pressure. These pressure transmitters are used when the measured pressure is not affected by any changes, such as temperature.
Differential pressure transmitter– Has two sensing diaphragms that measure the difference between two pressures. The differential pressure transmitter will then produce an output signal referenced to the calibrated pressure range. These devices are very commonly used to monitor various industrial processes.
What are the industrial applications of pressure sensors? The application field of pressure sensors is extremely broad, covering almost all occasions where pressure needs to be monitored and controlled. The following are some typical application areas:
Industrial control: used to monitor and control fluid pressure, such as flow metering, processing and control of pipelines, gases and liquids.
Automotive industry: plays an important role in the engine management system, brake system, tire pressure monitoring system and other aspects of automobiles.
Medical equipment: used to monitor the pressure in medical equipment such as blood pressure and ventilators, and provide important health data.
Environmental monitoring: used for atmospheric pressure detection, water pressure monitoring, and water level, liquid level and gas concentration measurement.
Oil field and energy field: used for oil well pressure control, pipeline monitoring, liquid level measurement, etc.
Aerospace field: pressure sensors are mainly used to monitor the cylinder pressure, engine intake pressure and atmospheric pressure of aircraft and spacecraft.
Chemical field: pressure sensors are mainly used to monitor the pressure changes of various chemical reactions and the liquid level height of liquids.
Food industry: Pressure sensors are mainly used to monitor pressure changes during food processing and pressure conditions of packaging containers.
