SDPB intelligent single crystal silicon differential pressure-pressure transmitter Suppliers

SDPB single crystal silicon pressure transmitter adopts single crystal silicon technology pressure sensor. The single crystal silicon pressure sensor is located on the top of the metal body, away from the contact surface of the medium, to achieve mechanical isolation and thermal isolation. The glass sintered integrated sensor lead and the high strength of the metal substrate Electrical insulation improves the flexibility of electronic circuits and the ability to withstand transient voltage protection, can cope with complex chemical occasions and mechanical loads, and has strong anti-electromagnetic interference capabilities, suitable for pressure and liquid level in harsh process industrial environments or flow measurement applications.

What is SDPB intelligent single crystal silicon differential pressure-pressure transmitter
SDPB stands for "Silicon Differential Pressure-Pressure Transmitter with Single Crystal Diaphragm and Intelligent Compensation." It is a type of pressure transmitter that is designed to measure differential pressure (the difference between two pressure points) in various industrial applications.
The key feature of SDPB is its use of a single crystal silicon diaphragm. The diaphragm is a thin, flexible membrane that separates two pressure chambers in the transmitter. When the pressure difference across the diaphragm changes, it deflects, creating a proportional change in electrical output from the transmitter.
The use of single crystal silicon allows for high accuracy and stability over a wide range of temperatures and pressures. Additionally, the intelligent compensation feature of the transmitter helps to account for changes in temperature and other environmental factors that can affect the accuracy of the pressure measurement.
Use of SDPB intelligent single crystal silicon differential pressure-pressure transmitter
The SDPB intelligent single crystal silicon differential pressure-pressure transmitter is commonly used in various industrial applications where accurate and reliable pressure measurement is required. Some of the common uses of SDPB transmitters include:
1.Oil and gas processing: SDPB transmitters are used to measure differential pressures in oil and gas pipelines, refineries, and other processing facilities. This allows operators to monitor the flow of fluids and gases through the system and ensure that everything is running smoothly.
2.Chemical processing: In chemical processing plants, SDPB transmitters are used to monitor and control pressure in reaction vessels, distillation columns, and other critical equipment. This helps to ensure that the chemical reactions proceed smoothly and that the product quality is consistent.
3.HVAC systems: SDPB transmitters are used to measure differential pressures in heating, ventilation, and air conditioning (HVAC) systems. This allows building managers to maintain a comfortable and healthy indoor environment for occupants.
Advantages of SDPB intelligent single crystal silicon differential pressure-pressure transmitter
The SDPB intelligent single crystal silicon differential pressure-pressure transmitter offers several advantages over other types of pressure transmitters, including:
1.High accuracy: The use of a single crystal silicon diaphragm allows for very high accuracy in pressure measurement, with typical accuracies of up to 0.1% of full scale. This level of accuracy makes the SDPB transmitter suitable for use in applications where precise pressure measurement is critical.
2.Wide range: SDPB transmitters are capable of measuring pressure differences over a wide range, typically up to 10,000 psi. This makes them suitable for use in a variety of industrial applications, from low-pressure applications such as HVAC systems to high-pressure applications such as oil and gas processing.
3.High stability: The single crystal silicon diaphragm provides excellent long-term stability, even in harsh environments. This allows the transmitter to maintain its accuracy and reliability over time, without the need for frequent recalibration.
