Products Description
Product Definition
The Nexisense SMP4601 Series Universal Split Level Transmitter is a high-performance sensor designed specifically for liquid level measurement. It measures the static pressure of liquids to infer liquid depth and converts the measurement results into standard current or voltage signals for output. This transmitter is suitable for various liquid media, particularly excelling in industrial environments that require high precision and reliability.
Working Principle
The working principle of the SMP4601 Series Transmitter is based on the measurement of liquid static pressure. The depth of the liquid is proportional to its static pressure, and the sensor detects the pressure applied by the liquid on the isolation diaphragm. This pressure is converted into an electrical signal. After processing through a signal conditioning circuit, a standard 4mA to 20mA DC signal is output, facilitating connection and monitoring with other devices.
Structural Analysis
The structure of the SMP4601 Series Transmitter is designed with various application scenarios in mind and mainly consists of the following components:
Housing: Made of cast aluminum, providing excellent explosion-proof performance suitable for harsh environments.
Sensor: The core component is a high-performance diffusion silicon pressure sensor, ensuring measurement accuracy and stability.
Isolation Diaphragm: Made of stainless steel 316L, highly resistant to corrosion and suitable for various liquid media.
Display Unit: Optional LCD or LED digital display for real-time monitoring of liquid levels.
Measurement Method
The measurement method of the SMP4601 Series Transmitter is based on the principle of liquid static pressure. It follows these steps for liquid level measurement:
Liquid Static Pressure Sensing: The liquid applies pressure on the isolation diaphragm, which is sensed by the sensor.
Signal Conversion: The sensor converts the pressure signal into an electrical signal.
Signal Conditioning: The electrical signal is processed through a signal conditioning circuit to output standard current or voltage signals.
Data Transmission and Display: The output is connected to a display unit or control system for real-time liquid level display.
