Ưu điểm kỹ thuật quan trọng
-
High-Precision Metallic Sensor: The PMP71B offers an exceptional accuracy of up to +/- 0.025%. Its robust metallic diaphragm is designed to handle high-pressure cycles and vacuum applications with long-term stability.
-
SmartBlue App Connectivity: Operators can remotely control and configure the transmitter via a secure Bluetooth connection. This allows for safe commissioning and maintenance from a mobile device, especially in hard-to-reach or hazardous areas, without the need for a physical cable.
-
Intuitive Software Wizards: The device software includes guided wizards that simplify complex tasks. These lead the user through setup, SIL commissioning, and proof testing, significantly reducing the risk of human error.
-
Advanced Heartbeat Technology: This suite provides continuous self-diagnostics and verification without process interruption. It can detect anomalies such as changes in loop characteristics or plugged impulse lines, ensuring the device is always operating within specification.
-
Visual Status Indication: The backlit display provides immediate feedback on the health of the instrument. In the event of a diagnostic message, the display background changes from green to red, allowing maintenance teams to identify issues at a glance.
-
Extreme Temperature Capability: When paired with diaphragm seals, the PMP71B can handle process temperatures as high as 400°C (752 °F), making it suitable for hot oil, steam, and chemical synthesis applications.
