Products Description
Product Definition
The Nexisense SMP4602 Series Universal Submersible Level Transmitter is a high-precision level measurement device that employs advanced silicon piezoresistive pressure sensors as its core measurement component. Its design aims to provide reliable level monitoring solutions, widely used in industries such as petroleum, metallurgy, power, pharmaceuticals, and water supply and drainage.
Working Principle
The SMP4602 Series Level Transmitter determines the depth of the liquid by measuring the static pressure exerted by the liquid. The depth of the liquid is proportional to its static pressure, and the transmitter converts the measured pressure signal into a standard current or voltage output signal through a signal conditioning circuit. This signal can be directly read by monitoring systems, enabling real-time monitoring of the liquid level.
Structural Analysis
The structural design of the SMP4602 Series Level Transmitter fully considers the harsh conditions of industrial environments and consists of the following main components:
Housing: Made of stainless steel 316L, it offers excellent corrosion resistance and mechanical strength.
Isolation Diaphragm: Utilizes high-performance materials to ensure effective isolation between the liquid and the sensor, preventing direct contact.
Cable: Equipped with a dedicated polyethylene cable to ensure stability and durability in various environments.
Terminal Block: Designed for easy electrical connection by users.
Measurement Method
The SMP4602 Series Level Transmitter supports multiple measurement ranges, as detailed below:
| Measurement Range | Measurement Scope |
|---|---|
| 0 mH2O～1 mH2O | 0 mH2O～500 mH2O |
| Overload Capacity | 2 times the full-scale pressure, 5 times for ranges below 5 mH2O |
The transmitter offers various output signal types, allowing users to select the appropriate output method based on their needs:
