1. Floating ball liquid level transmitter
The float type liquid level transmitter consists of a magnetic float, measuring conduit, signal unit, electronic unit, junction box, and installation components.
Generally, the specific gravity of a magnetic float is less than 0.5, and it can float above the liquid surface and move up and down along the measuring tube. The catheter is equipped with a measuring component that can convert the measured liquid level signal into a resistance signal proportional to the liquid level change under external magnetic action, and convert the electronic unit into 4-20mA or other standard signal output. This transmitter is a modular circuit with advantages such as acid resistance, moisture resistance, shock resistance, and corrosion resistance. The circuit contains a constant current feedback circuit and an internal protection circuit, which can ensure that the output current does not exceed 28mA. Therefore, it can reliably protect the power supply and prevent damage to the secondary instrument.
2. Float type liquid level transmitter
The float type liquid level transmitter is designed based on the Archimedes buoyancy principle by replacing the magnetic float with a float. Float type liquid level transmitter uses tiny metal film strain sensing technology to measure the liquid level, boundary or density of liquids. It can perform routine setting operations through on-site buttons during operation.
3. Static pressure or liquid level transmitter
This transmitter operates based on the measurement principle of liquid static pressure. It generally uses a silicon pressure sensor to convert the measured pressure into an electrical signal, which is then amplified by an amplification circuit and compensated by a compensation circuit, and then output in the form of 4-20mA or 0-10mA current.
