Pressure type level Transmitter
Operating Principle:
A pressure type level transmitter is a device used to measure the level of a liquid or solid material in a tank, vessel, or container by converting the applied pressure into an electrical signal. It is commonly used in industrial applications such as oil and gas, chemical processing, water treatment, and manufacturing.
The transmitter consists of a pressure sensor, which is typically a diaphragm or a sensing element, and an electronic circuitry for signal processing. The diaphragm or sensing element is in contact with the substance whose level needs to be measured. As the level changes, it exerts a pressure on the diaphragm, which deforms and generates a corresponding pressure signal.
The pressure signal is then converted into an electrical signal, usually a 4-20 mA current signal or a digital signal, by the electronic circuitry within the transmitter. This electrical signal can be transmitted to a control system, a data acquisition system, or a display unit for further processing, monitoring, and control.
