Product Introduction
The liquid level transmitter uses a high-performance diffusion silicon piezoresistive pressure sensor as the measuring element to accurately measure the static pressure of the liquid proportional to the depth of the liquid level, and converts it into a standard (current or voltage) signal output through a signal conditioning circuit, establishing a linear correspondence between the output signal and the depth of the liquid, and realizing the measurement of the depth of the liquid. The internal dedicated integrated circuit converts the sensor millivolt signal into a standard long-distance transmission current signal, which can be directly connected to computer interface cards, control instruments, intelligent instruments, or PLCs for convenient connection. The product has high precision and small volume. It can be directly put into the liquid to measure the liquid height from the end of the transmitter to the liquid level, making it easy to use.
Suitable for liquid level measurement and control in the fields of petroleum, chemical, power plants, urban water supply, and hydrological exploration.
