Products Description
Product Overview
Nexisense SMP4027 is a cost-effective, high-quality pressure measurement device designed for OEM, commercial, and industrial applications. It utilizes advanced piezoresistive sensor technology, which enables precise pressure measurement of gases and liquids in various applications such as hydraulic control, air conditioning units, refrigeration systems, and water treatment facilities.
Definition
A pressure transmitter is a device usedto measure the pressure of a liquid or gas and convert the measurement intoa standard electrical signal. This signal is often in the form of 4-20mA or 0.5-4.5V, which is proportional to the pressure applied. The SMP4027 pressure transmitter utilizes precise measuring technology to meet the demands of various industrial applications.
Working Principle
The SMP4027 pressure transmitter works based on the piezoresistive sensing technology. The core component is a ceramic pressure sensor that generates a small change in electrical resistance when external pressure is applied. This change is converted into an electricalsignal, which is processed through internal digital compensation and calibration techniques. The final output signal is a linear representation of the measured pressure.
Structure Analysis
The SMP4027 pressure transmitter consists of the following main components:
Pressure Sensor Core: Made of imported ceramic material, this sensor can withstand high pressures and corrosive media environments, ensuring long-term stability and reliability.
Housing: Made of stainless steel, the housing is highly resistant to corrosion and protects the internal components from external environmental influences.
Electrical Connection Ports: Supports multiple electrical connection types such as Packard, DIN43650C, M12 series, and Cable, meeting diverse application requirements.
Output Signal Module: Provides standard 4-20mA current output and 0.5-4.5V voltage output, compatible with different control systems.
Pressure Interface: Supports various pressure interfaces like G1/4, NPT1/4, and 7/16-20UNF to adapt to different installation and application scenarios.
Measurement Method
The SMP4027 pressure transmitter uses piezoresistive sensor technology, where the electrical resistance of the pressure sensing element changes in direct proportion to the applied pressure. This changeis converted into a standard electrical signal by the transmitter's internal circuitry. The output signal’s magnitude correlates with the measured pressure, and users can determine the pressure level based on the signal strength.
