Working principle of differential pressure transmitter The working principle of differential pressure transmitter: the process pressure is passed through the isolation diaphragm on both sides or one side, and the filling liquid acts on the measuring diaphragm which is tensioned in the sensitive component, measuring the diaphragm and two The capacitor plates on the side insulators form a capacitor, and the diaphragm is in the middle position when no pressure is applied or the pressures on both sides are equal, and the capacitances of the two capacitors are equal.
Accelerometer Sensor are widely used to monitor vibration in aerospace, automotive and manufacturing applications. Mechanical engineers often use them to diagnose problems with rotating equipment or assess the stability of structures that are subject to periodic stresses (such as monitoring the vibrations caused by trains/trucks crossing bridges, etc.) They are also often used in monitoring for condition-based maintenance, allowing engineers to examine the vibrations produced by a piece of equipment to assess its health, and monitoring the stresses sensitive equipment undergoes during transportation.
The most common method of acquiring vibration data involves connecting Accelerometer vibration sensor and configuring them into a data acquisition system that can deliver high-resolution (24-bit) vibration data at very high sample rates. Modern data acquisition systems can plot, log, filter, and analyze vibration data in real time, and allow using a variety of accelerometer types.
When the pressures on both sides are inconsistent, the measurement diaphragm is displaced, and the displacement is proportional to the pressure difference. This displacement is converted into a differential capacitance formed on the capacitor plate, and the differential capacitance is converted into 4~20mADC by the electronic circuit. The two-wire current signal is the working principle of the differential pressure transmitter.
The differential pressure transmitter is the most commonly used weight transmitter in industrial practice. It is widely used in various industrial self-control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical , oil wells, electricity, ships, machine tools, pipelines and many other industries.
There are many types of differential pressure transmitters, such as resistance strain gauge differential pressure transmitter, semiconductor strain gauge differential pressure transmitter, piezoresistive differential pressure transmitter, inductive differential pressure transmitter, capacitive differential pressure Transmitter, resonant differential pressure transmitter and capacitive accelerometer.
