QDL80D-BJ Alarm Pressure Switch
On-site Pressure Alarm for Faster Abnormality DetectionQDL80D-BJ is a digital pressure switch designed around “On-site Pressure Alarm for Faster Abnormality Detection.” Provides clear switching, alarm or relay functions for equipment control and interlocking. The alarm, relay, switching or control function turns the measured condition into a clear action for pumps, valves, warning devices or equipment interlocks. The feature is directly relevant to pressure monitoring, compressed air system and industrial process projects. Respond faster to abnormal conditions and equipment control demands, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. |  |
Relay Control & Alarm InterlockingQDL80D-BJ is a digital pressure switch designed around “Relay Control & Alarm Interlocking.” Provides clear switching, alarm or relay functions for equipment control and interlocking. The alarm, relay, switching or control function turns the measured condition into a clear action for pumps, valves, warning devices or equipment interlocks. The feature is directly relevant to pressure monitoring, compressed air system and industrial process projects. Respond faster to abnormal conditions and equipment control demands, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. |  |
Standard Pressure Output for Control SystemsQDL80D-BJ is a digital pressure switch designed around “Standard Pressure Output for Control Systems.” Transfers the measured pressure to PLC, DCS or remote monitoring systems. 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, 20mA. The feature is directly relevant to pressure monitoring, compressed air system 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. |  |
