QDFC70D Explosion-Proof Differential Pressure Transmitter
QDFC70D is a differential air pressure transmitter designed around “Intrinsically Safe Air Pressure Isolation.” Separates the hazardous-area air pressure loop from the safe-side control system. The isolated signal path separates the hazardous-area device from the safe-side control system and helps limit unwanted electrical interaction across the barrier. The feature is directly relevant to boiler system, chemical process and industrial process projects. Protect hazardous-area loops while keeping safe-side data stable, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
QDFC70D is a differential air pressure transmitter designed around “Stable Air Pressure Performance for Industrial Monitoring.” Improves air pressure stability, response or operating efficiency under changing field conditions. The stated operating range, accuracy, response, overload or stability feature supports more dependable data under changing field conditions. The feature is directly relevant to boiler system, chemical process and industrial process projects. Maintain clearer trend data during long-term industrial operation, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
QDFC70D is a differential air pressure transmitter designed around “Multiple Output Signals for Remote System Integration.” Supports 4–20mA, 0–5V, 0–10V, 1–5V, RS485 for stable air pressure measurement and system integration. The standardized signal path routes the measured value to PLCs, DCS platforms, displays or remote monitoring equipment. The confirmed values highlighted here are 4–20mA, 0–5V, 0–10V, 1–5V. The feature is directly relevant to boiler system, chemical process and industrial process projects. Connect field measurements directly to existing plc and monitoring systems, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
