Short Product Summary：
1，The PT-219 Pressure Transmitter is a heavy-duty, high-precision industrial pressure sensor designed for reliable fluid and gas pressure measurement. Built with a world-class diffused silicon piezoresistive sensor core and an advanced ASIC signal-conditioning chip, the PT-219 delivers exceptional accuracy with digital non-linear correction and wide-temperature compensation.
2，Featuring a fully welded hermetic seal and an integrated spin-riveted housing, the PT-219 eliminates structural thread-loosening risks, offering superior IP-rated waterproof performance and long-term durability. It supports flexible analog (4–20mA, 0–10VDC) and digital (RS485 Modbus, I2C) signal outputs for seamless integration into industrial automation networks.
Key Features & Benefits：
1，High-Performance Piezoresistive Silicon Core: Powered by an internationally sourced diffused silicon sensor element paired with a high-integration bridge signal-conditioning ASIC for ultra-high sensitivity and minimal signal drift.
2，Integrated Spin-Riveted & Hermetically Welded Housing: Utilizes a custom-molded, spin-riveted enclosure with full-seal welding technology—eliminating the risk of loose threads found in conventional connectors and providing maximum waterproof protection.
3，Precision Digital Temperature Compensation: Advanced digital calibration and full-temperature range compensation ensure outstanding accuracy and electrical stability under severe thermal fluctuations.
4，Versatile Signal Outputs & Waterproof Ventilation: Offers 2-wire 4–20mA, 0–10VDC, RS485 (Modbus-RTU), and I2C outputs. The connector features a waterproof breathable membrane and is fully compatible with standard Hirschmann and HTP sockets.
5，Customizable Process Connections: Flexible process interface configurations (e.g., G1/4", NPT1/4", M20×1.5) and custom thread options available to fit various piping and manifold setups.
6，Cost-Effective OEM Solution: High EMI/RFI noise immunity and strong anti-vibration performance make it a reliable choice for OEM machinery and large-scale industrial projects.
Industrial Applications：
1，Water Supply & Pump Systems: Variable frequency drive (VFD) pumps, booster pump sets, and municipal water networks.
2，HVAC & Compressor Units: Air compressors, chillers, commercial refrigeration, and environmental control systems.
3，Petrochemical & Energy: Oil & gas pipelines, power plant monitoring, and chemical processing automation.
4，Industrial Automation & Hydraulics: Hydraulic systems, pneumatic tools, metallurgy equipment, and heavy machinery.
