Overview
The BDK15 pressure sensor is a industrial-grade device designed for accurate pressure monitoring in demanding environments. It is engineered to withstand harsh conditions, including exposure to corrosive media and temperature fluctuations. As a piezoresistive sensor, it utilizes a Wheatstone bridge configuration to deliver stable and repeatable measurements. Its compact design and standardized mounting options make it compatible with a wide range of industrial systems.
Structure and Working Principle
The sensor consists of a pressure port, sensing element, signal conditioning circuitry, and electrical connection. The stainless steel diaphragm deflects under pressure, causing strain in the embedded piezoresistors. The resulting resistance change is converted to a proportional electrical output through onboard electronics. Advanced models may include temperature compensation and digital signal processing for improved accuracy across operating conditions.
Key Features
The BDK15 series stands out for its 0.25% to 0.5% full-scale accuracy, making it suitable for precision applications. Its robust 316L stainless steel construction ensures long-term reliability in corrosive environments. Additional features may include optional explosion-proof certifications (ATEX), IP67/IP68 protection ratings, and custom calibration options. The sensor's wide operating temperature range allows deployment in both indoor and outdoor installations.
Application Areas
Primary applications include hydraulic power units, compressor monitoring, and industrial process control systems. In manufacturing, these sensors are critical for maintaining optimal pressure in injection molding and CNC machinery. The oil and gas industry utilizes them for wellhead monitoring and pipeline pressure management. They're also integrated into HVAC systems for building automation and energy management applications.
Maintenance and Precautions
Regular inspection should check for seal integrity and electrical connection corrosion. Use appropriate thread sealants during installation to prevent media leakage. Avoid exposing the sensor to pressures beyond its rated capacity, even momentarily. When measuring aggressive media, consider diaphragm protection systems or chemical-resistant barrier fluids for extended service life.
B2B Procurement Guide
Industrial buyers should specify the pressure range (e.g., 0-100 bar), accuracy class, and electrical output requirements. Lead times typically range from 2-6 weeks for standard configurations. For large volume purchases (100+ units), negotiate calibration certificates and extended warranties. Verify supplier certifications, particularly for hazardous area installations requiring ATEX or IECEx compliance.
