مجالات التطبيق
Open/closed position feedback for quarter-turn valves complying with VDI/VDE 3845
Can be directly mounted on quarter-turn valve actuators complying with NAMUR/VDI VDE 3845 standards. Two independent non-contact inductive sensors separately indicate the valve open and closed positions, providing valve status feedback for process control.
Valve position monitoring in high-pressure or corrosive washdown environments
The DC 2-wire output version features IP66/67/69K protection and a sealed design. It can be used in environments subject to high-pressure or corrosive washdown to monitor the open and closed positions of quarter-turn valves.
Valve status confirmation in hazardous-area processing environments
The product is available with intrinsically safe NAMUR and DC 2-wire output configurations. The DC 2-wire output sensor is suitable for hazardous-area processing environments and can be used for open/closed position confirmation and process-control status feedback with compatible quarter-turn valve actuators.
Valve monitoring in dirty processing and fast-cycling applications
Suitable for quarter-turn valve position monitoring in dirty processing environments and fast-cycling applications. Non-contact detection avoids mechanical wear, while the rugged design resists impact, vibration, ultraviolet radiation and corrosion.
نقاط الاختيار
Direct-mount design compliant with VDI/VDE 3845
The 54-HS Series complies with NAMUR/VDI VDE 3845 mounting standards and can be directly mounted on quarter-turn actuators that conform to these standards.
Non-contact inductive detection
The product uses non-contact inductive sensors to detect valve open and closed positions, avoiding mechanical contact wear and supporting valve position monitoring in fast-cycling and contaminated environments.
Independent dual-sensor detection for open and closed positions
The product includes two independent inductive sensors that separately indicate the valve open and closed positions for position feedback from quarter-turn valve actuators.
Intrinsically safe NAMUR and DC 2-wire output options
The 54-HS Series provides intrinsically safe NAMUR and DC 2-wire signal options, allowing selection of the appropriate version according to the site control system and application environment.
Sealed design with multiple protection ratings
The product uses a sealed construction to prevent liquid or solid ingress. It provides IP67 protection for the intrinsically safe version and IP66, IP67 and IP69K protection for the DC 2-wire output version, making it suitable for high-pressure and corrosive washdown environments.
ملاحظات التركيب والصيانة
Confirm compatibility with the NAMUR/VDI VDE 3845 mounting interface
During installation, confirm that the Bray 54-HS Series sensor is used with a quarter-turn valve actuator complying with NAMUR/VDI VDE 3845 standards, and ensure that the mounting interface matches the valve position arrangement.
Keep the target within the rated operating distance
During installation and commissioning, ensure that the actuator target is within the rated operating distance of the corresponding sensor: 0 to 2.4mm for the intrinsically safe NAMUR version and 0 to 2.05mm for the DC 2-wire version.
Match the output version to the operating voltage
Before wiring, confirm the sensor output version and operating voltage: 8V for the intrinsically safe NAMUR version and 6 to 30V for the DC 2-wire version.
Control temperature and meet protection requirements
The installation environment must comply with the temperature range for the applicable output version and meet the corresponding protection rating: –25 to 100°C and IP67 for the intrinsically safe NAMUR version; –40 to 75°C and IP66/IP67/IP69K for the DC 2-wire version.
