The pressure indicator refers to instruments used to measure gas and liquid pressure, usually divided into mechanical pressure indicator, electronic pressure indicator and mechatronic pressure indicator. 1. Electronic pressure indicator The basic component of the electronic pressure indicator is the pressure sensor, which can convert the pressure measurement parameters into electronic signals. The advantages of […]
Ⅰ. Structures of the capacitive pressure sensor The capacitive pressure sensors are based on silicon materials, using capacitance changes to convert pressure into capacitance changes, and are made by MEMS technology. Ⅱ. Main problems of the capacitive pressure sensor Because its detection principle is to use capacitive pole pitch variation, however is itself nonlinear. […]
Pressure transmitters have been widely used in various working environments. Maybe everyone knows how to choose a pressure transmitter and how to use a pressure transmitter, but do you know how to maintain a pressure transmitter? What are the methods for daily maintenance of the pressure transmitter? 1. Itinerant inspection of pressure transmitter Check the […]
The pressure sensor is a device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. It is usually composed of pressure sensitive components and signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, […]
Many people don’t know how to choose a low differential pressure sensor that is suitable for their needs. Today, the precautions when choosing a low differential pressure sensor will be shared with you . 1. How much accuracy does the low differential pressure sensor need The accuracy is determined by the effects of nonlinearity, […]

The pressure is one of the important parameters in industrial production. To ensure the normal operation of production, pressure must be monitored and controlled. The following are the terms commonly used in the model selection of the low differential pressure sensor: 1. Standard pressure It refers to the magnitude expressed by taking the atmospheric pressure […]
A brief introduction of capacitive pressure sensor The ceramic capacitive pressure sensor uses a ceramic diaphragm as a pressure-sensitive element. The ceramic diaphragm and the ceramic substrate are respectively made into the two poles of the capacitor. When external pressure acts on the ceramic diaphragm, the ceramic diaphragm is deformed and the distance between the […]
Ⅰ. Four common faults of pressure transducers The first fault is that when the pressure goes up, the pressure transmitter output cannot go up. In this case, check whether the pressure port is leaking or blocked first. If not, check the wiring method and the power supply. If the power supply is normal, simply pressurize […]
The main purpose of the negative pressure isolation room is to separate the patient from the surrounding environment and people, avoid direct contact with the body or air exchange, and prevent cross-infection. The main building of the negative pressure isolation room must reach the airtight level, and the gap between the electromechanical system and the […]
