This series of transmitters supports gauge pressure, absolute pressure and negative pressure measurement. The output signal is standard 4-20mA (RS485 optional), and can be used with moving-coil indicators, digital pressure gauges, electronic potentiometers and other instruments to achieve accurate pressure measurement and control. It is widely suitable for continuous pressure monitoring occasions such as water vapor, air, corrosive media, high-voltage switchgear, flue gas emission, water supply pipe network, liquid medicine filtration, fermentation tank, boiler water supply, etc.

Core Technical Parameters

The product adopts an integrated compact design, which is convenient for installation and maintenance, and is suitable for complex industrial site conditions.

Working Principle and Design Advantages

The core of the YD-2088 diffusion silicon pressure transmitter adopts a piezoresistive diffusion silicon sensitive element. When the measured pressure acts on the 316L stainless steel isolation diaphragm, the pressure is transmitted to the diffusion silicon core through the filling liquid, causing resistance changes and outputting a millivolt-level signal. After amplification, linear compensation and temperature compensation, the signal is converted into a standard 4-20mA or RS485 digital signal.

The main design advantages include:

• High stability and interchangeability: Imported diffusion silicon or ceramic core, wide temperature compensation range, excellent long-term stability.

• Strong anti-interference ability: Integrated signal processing circuit with good electromagnetic interference resistance.

• Flexible output configuration: Supports 4-20mA analog output and RS485 digital output, which can be directly connected to PLC, DCS and SCADA systems.

• Wide temperature working range: -40℃～80℃ industrial-grade temperature adaptability, meeting the needs of most industrial sites.

• 316L stainless steel isolation diaphragm: Strong corrosion resistance, suitable for measurement of various media.

These features enable the YD-2088 series to exhibit good long-term stability and compatibility in process control systems.

Typical Application Scenarios

Nexisense YD-2088 diffusion silicon pressure transmitter is widely used in the following industrial fields:

• Petrochemical and process industries: Pressure monitoring of reaction kettles, pipelines and storage tanks, supporting measurement of corrosive media.

• Power and energy systems: Pressure monitoring of boilers, steam turbines and high/low voltage switchgear.

• Metallurgy and building materials industry: Pressure measurement of furnace kilns and gas pipelines.

• Water treatment and environmental protection projects: Pressure collection in pumping stations, filtration systems and sewage treatment, connected to SCADA for remote monitoring.

• Pharmaceutical and food processing: Pressure control of clean process pipelines, liquid medicine filtration and fermentation tank pressure monitoring.

• Building water supply and drainage and air conditioning systems: Water flow indication in high-rise building water supply pipe networks and pressure monitoring of air conditioning ducts.

In industrial Internet of Things projects, the device can be used as an edge node to access PLC or gateways through RS485 interface to achieve remote pressure data collection and predictive maintenance.

Selection Guide

When selecting for engineering projects, it is recommended to focus on the following parameters:

• Measuring range: Select the appropriate range according to the maximum working pressure of the process. It is recommended that the working pressure be in the 30%-80% range of the range to ensure long-term stability.

• Accuracy grade: For conventional process control, choose 0.5 or 0.25 grade; for key control points or metering applications, 0.1 grade is recommended.

• Output signal: When remote transmission or PLC/DCS connection is required, priority should be given to the 4-20mA + RS485 version.

• Medium compatibility: Confirm the corrosiveness of the medium to 316L stainless steel. Special diaphragm materials can be customized if necessary.

• Installation environment: Evaluate the on-site temperature, vibration and protection requirements, and select the corresponding electrical interface and protection grade.

Nexisense provides detailed selection manuals and technical support, and can recommend the optimal configuration according to specific project working conditions.

System Integration, Protocol Compatibility and Installation Precautions
