Products Description
Product Definition
The Nexisense SMP4630 series intelligent liquid level transmitter is a high-tech product that analyzes and calculates the inherent pressure and temperature characteristics of the sensor through digital signals, providing precise corrections and compensations. Its design aims to offer high-precision liquid level measurement solutions, widely applicable in various industrial and environmental monitoring scenarios.
Principle
The SMP4630 series transmitter operates on the principle of pressure measurement. It measures the pressure exerted by the liquid on the sensor and, combined with temperature compensation algorithms, accurately calculates the liquid level height. The device outputs liquid level signals via the RS485 Modbus protocol, facilitating data interaction with other devices for remote monitoring and management.
Structural Analysis
The structure of the SMP4630 series transmitter is designed with environmental adaptability and long-term stability in mind. The main structural components include:
Housing: Made of all stainless steel 316L material, offering excellent corrosion resistance and mechanical strength.
Probe: Designed with features to prevent sedimentation, puncturing by sharp objects, and marine biological growth, ensuring reliability in harsh environments.
Sealing Ring: Made of fluororubber material, providing excellent sealing performance to prevent liquid leakage.
Cable: Equipped with a dedicated polyethylene cable that is wear-resistant and suitable for various environments.
Measurement Method
The SMP4630 series transmitter adopts an immersion measurement method, directly submerged in the liquid for liquid level measurement. The measurement range can be customized according to needs, typically from 0 mH2O to 200 mH2O. Through the RS485 digital interface, the transmitter can connect to monitoring systems for real-time data transmission.
