Products Description
Product Definition
The Nexisense SMP4603 series submersible level transmitter is a high-precision measuring instrument designed for liquid depth measurement. It measures the static pressure of liquids and converts it into standard current or voltage output signals, widely used in industries such as oil, chemical, and power.
Working Principle
The core principle of the SMP4603 series level transmitter is the use of a silicon pressure sensor. This sensor can detect the static pressure generated by the liquid depth and convert it into an electrical signal. The specific process is as follows:
Pressure Sensing: The greater the liquid depth, the higher the static pressure generated. The sensor measures this change to obtain liquid level information.
Signal Conditioning: The signal output from the sensor is conditioned by internal circuits, converting it into standard current (4mA～20mA) or voltage (0V～10V) signals.
Output: The conditioned signal can be directly used for monitoring and control systems, ensuring real-time liquid level monitoring.
Structural Analysis
The structure of the SMP4603 series level transmitter is robust, made of stainless steel 316L, providing excellent corrosion resistance and mechanical strength. Its main structural components include:
Housing: Stainless steel 316L, ensuring durability and protection.
