Application scenarios
Open/closed position feedback for quarter-turn valves compliant with VDI/VDE 3845
Mounts directly to quarter-turn valve actuators compliant with NAMUR/VDI VDE 3845. Two independent non-contact inductive sensors separately indicate valve open and closed positions, providing valve position status feedback for process control.
Valve position monitoring in high-pressure or corrosive washdown environments
The DC 2-wire output version features an IP66/67/69K protection rating and a sealed design, making it suitable for environments with high-pressure washdown or corrosive washdown conditions to monitor the open and closed positions of quarter-turn valves.
Valve status confirmation in hazardous-area processing environments
The product is available in intrinsically safe NAMUR and DC 2-wire output configurations. DC 2-wire output sensors are suitable for hazardous-area processing environments and can be used to confirm open and closed positions and provide process control status feedback for compatible quarter-turn valve actuators.
Valve monitoring in dirty processing and fast-cycle applications
Suitable for quarter-turn valve position monitoring in dirty processing environments and fast-cycle applications. Non-contact sensing prevents mechanical wear, while the rugged design resists impact, vibration, ultraviolet radiation, and corrosion.
Selection points
Direct-Mount Design to VDI/VDE 3845 Standard
The Series 54-HS complies with NAMUR/VDI VDE 3845 mounting standards and can be mounted directly on quarter-turn actuators conforming to this standard.
Non-Contact Inductive Detection Design
The product uses non-contact inductive sensors to detect valve open and closed positions, eliminating mechanical contact wear and making it suitable for valve position monitoring in fast-cycling and contaminated environments.
Independent Dual-Sensor Detection for Open and Closed Positions
The product is equipped with two independent inductive sensors that provide valve open and closed position indication, respectively, for position feedback on quarter-turn valve actuators.
Intrinsically Safe NAMUR and DC 2-Wire Output Options
The Series 54-HS offers both intrinsically safe NAMUR and DC 2-wire output signal options, allowing selection of the appropriate version based on the on-site control system and application environment.
Sealed Design with Multiple Protection Ratings
The product features a sealed construction to prevent liquid or solid ingress and 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 washdown and corrosive washdown environments.
Installation & maintenance notes
Verify Compliance with the NAMUR/VDI VDE 3845 Mounting Interface
During installation, verify that the Bray Series 54-HS sensor is used with a quarter-turn valve actuator compliant with NAMUR/VDI VDE 3845 and ensure that the mounting interface matches the valve position structure.
Ensure the Target Is 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 2.4 mm for the intrinsically safe NAMUR version and 0 to 2.05 mm for the DC 2-wire version.
Match the Output Version and Operating Voltage
Before wiring, confirm the sensor output version and its operating voltage: 8V for the intrinsically safe NAMUR version and 6 to 30V for the DC 2-wire version.
Control Temperature and Meet Protection Rating Requirements
The installation environment must comply with the temperature range for the applicable output version and meet the corresponding protection rating requirements: –25 to 100°C, IP67 for the intrinsically safe NAMUR version; –40 to 75°C, IP66/IP67/IP69K for the DC 2-wire version.
FAQ
How does the Series 54-HS proximity sensor provide valve position indication?
The Series 54-HS uses two independent sensors to indicate the valve open and closed positions separately, enabling precise valve positioning and monitoring.
What actuator compatibility requirements apply to sensor installation?
The compact design mounts directly to actuators compliant with the VDI/VDE 3845 standard, enabling a smaller actuator footprint and cost savings.
What output options are available for the Series 54-HS, and how can it be integrated into a process control environment?
Multiple electrical outputs are available, including intrinsically safe NAMUR and DC 2-wire output (NO), allowing the Series 54 to be integrated into standard process control environments.
How does the sensor perform in harsh or contaminated environments?
The sensor is tightly sealed to prevent the ingress of liquids or solids, making it suitable for dirty processing environments, high-pressure washdown, and corrosive washdown applications. It also offers impact resistance, vibration resistance, UV resistance, and corrosion resistance.
What advantages does the Series 54-HS offer for installation and maintenance?
The design emphasizes fast, simple installation and non-contact sensing to reduce mechanical wear. LED indicators display power, switching, and solenoid status, and DC 2-wire output products are available for hazardous-area environments.
