Products Description
Product Definition
The GPD60 Mine Pressure Transmitter is a high-precision pressure measurement device launched by Nexisense, specifically designed for pressure monitoring and control in industries such as coal mining, petroleum, chemical engineering, and electricity. It employs advanced piezoresistive sensor technology combined with a stainless steel isolation membrane to ensure the stability and reliability of the device in high-pressure environments.
Principle
The core working principle of the GPD60 Mine Pressure Transmitter is based on piezoresistive sensor technology. This sensor measures the effect of pressure on its electrical resistance, converting the pressure signal into an electrical signal. Specifically, when pressure is applied to the sensitive element of the sensor, the resistance value changes, which is then converted into a corresponding voltage output signal. Through a precision signal processing circuit, this voltage signal is further converted into a standard output signal for subsequent device use.
Structure Analysis
The structural design of the GPD60 Mine Pressure Transmitter fully considers various needs in industrial applications, as detailed below:
Shell Material: All stainless steel construction, providing excellent corrosion resistance and mechanical strength, suitable for various harsh environments.
Protection Level: IP65, ensuring normal operation in humid or dusty environments.
Pressure Interface: Uses DN10 standard interface for easy connection with other devices.
Sensor: Made of 316L stainless steel, applicable to various fluids, ensuring long-term stability.
Measurement Method
The GPD60 Mine Pressure Transmitter employs absolute pressure measurement, with a range covering from 0MPa to 60MPa and an overload capacity of 2 times the full-scale pressure or 110MPa (whichever is smaller). The output signal of the transmitter can be selected as 0.5V~4.5V or 1~5V, accommodating different application needs.
