Products Description
Nexisense SMP4015 Series Small High-Pressure Pressure Transmitter
Product Definition
The Nexisense SMP4015 series small high-pressure pressure transmitter is a high-precision device used for measuring the pressure of liquids and gases. This series of products utilizes silicon strain technology and high-temperature sintering processes, ensuring excellent long-term stability and overload resistance, suitable for various industrial environments.
Principle
The SMP4015 series pressure transmitter measures pressure by converting the strain signal generated by its internal sensor. The core principle relies on the piezoelectric effect; when pressure is applied to the sensor, the internal strain gauge deforms, producing an electrical signal proportional to the pressure. This signal is amplified and processed, outputting standard current or voltage signals for subsequent device use.
Structure Analysis
The structure of the SMP4015 series pressure transmitter is compact and primarily consists of the following components:
Housing: Made of stainless steel, providing good corrosion resistance and mechanical strength.
Sensor: Integrates high-stability silicon strain gauges to ensure measurement accuracy.
Electrical Interface: Offers various electrical connection methods for easy integration with different devices.
Sealing Structure: O-ring-free sealing design to avoid potential leakage risks and ensure long-term stable operation.
Measurement Methods
The SMP4015 series pressure transmitter supports various measurement methods, including:
Gauge Pressure Measurement: Suitable for measuring pressure relative to atmospheric pressure.
Absolute Pressure Measurement: Suitable for applications requiring absolute pressure values.
Differential Pressure Measurement: Used for measuring the difference between two pressure points.
