Products Description
Nexisense SMP4008 Series General Pressure Transmitter Details
Product Definition
The Nexisense SMP4008 series general pressure transmitter is a high-precision pressure sensor capable of real-time monitoring and controlling fluid pressure. This product adopts a piezoresistive sensor technology with adjustable zero and full-scale output, widely used in various industrial fields.
Working Principle
The working principle of the SMP4008 series pressure transmitter is based on the piezoresistive effect. When pressure is applied to the sensitive element of the sensor, it causes a change in its resistance. Through precise circuit design, the transmitter converts this resistance change into a linear voltage or current signal, facilitating subsequent monitoring and control.
Structure Analysis
The structural design of this series of pressure transmitters emphasizes reliability and durability, mainly consisting of the following components:
Housing: Made of stainless steel, providing excellent corrosion resistance and mechanical strength.
Sensor: Utilizes a high-stability, high-reliability piezoresistive sensor to ensure long-term stable performance.
Seal Ring: Fluororubber seal ring guarantees the product's sealing performance in various environments.
Cable: Equipped with a dedicated polyethylene cable, suitable for various industrial environments.
Measurement Methods
The SMP4008 series supports multiple measurement methods, including gauge pressure, absolute pressure, and sealed gauge pressure. The specific measurement ranges are shown in the table below:
