Pressure transmitters come in a variety of models, ranges, process connections, and materials. It can be widely used in many industrial fields of petroleum, chemical, power, metallurgy, pharmaceutical, food, etc., can be adapted to a variety of occasions and medium industrial measurement and is ideal for traditional pressure gauge and pressure transmitter upgrade traditional products, industrial automation Ideal pressure measuring instrument in the field.
Many people mistakenly think of pressure transmitters and pressure sensors as the same. They all represent sensors. Originally, they made a big difference. The external appearance of the pressure measurement in the appearance of the electrical tester is called a pressure sensor. Pressure sensors are usually composed of elastic sensitive elements and displacement sensitive elements. The function of the elastic sensitive element is to make the measured pressure act on a certain area and convert it into displacement or strain. Then the displacement sensitive element or strain gauge converts into an electrical signal that must be related to the pressure. Sometimes the functions of these two components are integrated, such as solid-state pressure sensors in piezoresistive sensors. Pressure is an important process parameter in the consumption process and in the aerospace, aviation, and defense industries. Not only does it need to suspend rapid and dynamic measurement, but it also digitizes and records the measurement results. The automation of large-scale refineries, chemical plants, power plants, and steel plants also requires the transmission of pressure parameters at far intervals, and requests the conversion of pressure and other parameters such as temperature, flow, and viscosity into digital signals for transmission to the computer. Therefore, the pressure sensor is a sensor that is highly valued and developed quickly. The deployment trend of pressure sensors is further advancement of dynamic response speed, accuracy and reliability, and completion of digitization and intelligence. Commonly used pressure sensors include capacitive pressure sensors, variable reluctance pressure sensors, Hall-type pressure sensors, fiber-optic pressure sensors, and resonant pressure sensors. As the skills advance, the meaning of some of the skills vocabulary has changed so much that it often leads to misunderstandings. The sensor is such a example.
There are many types of transmitters. The transmitters used in the appearance of industrial control include temperature transmitters, pressure transmitters, flow transmitters, current transmitters, voltage transmitters, and so on. The transmitter is equivalent to a signal amplifier. The transmitter powers the sensor and amplifies the signal. The sensor only collects the signal, for example, the strain gauge turns the displacement signal into a resistance signal. Of course, there are also sensors that do not have to be powered, such as thermocouples and piezoelectric ceramics, which are usually used.
The pressure sensor generally refers to a sensitive element that converts a changed pressure signal into a correspondingly changed resistance signal or capacitance signal, such as a piezoresistive element, a pressure-containing element, and the like. Generally refers to the pressure transmitter, the entire circuit unit measuring pressure sensitive element together with the circuit configuration of the scheduler, usually directly into a standard output pressure voltage signal or current signal of the linear relationship for appearance, plc, collected cards Equipment is collected directly.
