StoneL Quartz QN45 NAMUR Valve Monitor QN45CK02HDM QN45C02NRA QN45C03NRA QN45D05NRA QN45D06NRA QN45CR02HRA QN45K03HDM QN45K03SDM QN4XD05HRA

StoneL QN45CK02HDM is listed within the StoneL Quartz QN45 valve position monitoring family, designed for industrial automated valve status feedback. This product listing covers nine requested references: QN45C02NRA, QN45C03NRA, QN45D05NRA, QN45D06NRA, QN45CK02HDM, QN45CR02HRA, QN45K03HDM, QN45K03SDM and QN4XD05HRA.

The StoneL Quartz QN45 platform uses a dual NAMUR sensor module for valve position monitoring. The manufacturer identifies the QN45 sensor function with EN 60947-5-6 and intrinsically safe applications. However, the complete ordering code, certification and installation conditions must be verified for each requested configuration.

StoneL QN45CK02HDM Quartz NAMUR Valve Monitor

Valve position feedback is an essential part of automated process control. In a typical on/off valve assembly, position monitoring equipment helps communicate the valve’s open or closed status to a supervisory control system. This information can support plant operation, maintenance inspection and equipment status verification.

StoneL Quartz monitors combine industrial enclosure options, visual indication arrangements and different switching technologies. As a result, customers can select an ordering configuration that suits the valve actuator, electrical connection and installation environment. The QN45 family specifically identifies NAMUR dual-sensor technology.

For replacement projects, the exact StoneL model number is especially important. Similar-looking Quartz devices may have different sensor technologies, conduit entries, indicator arrangements or connection requirements. Therefore, customers should compare the complete original nameplate before ordering.

Available StoneL Quartz QN45 Models

This WooCommerce variable product includes nine model references. Customers can choose the exact part number required for maintenance, replacement or a new valve automation project. Nevertheless, model variations should not be treated as electrically or mechanically interchangeable without technical verification.

Important: The QN4XD05HRA reference is retained exactly as supplied. Its sensor function should not be assumed to match QN45 without checking the original manufacturer documentation.

Key Features of StoneL Quartz QN45

NAMUR Dual-Sensor Position Feedback

The standard QN45 function identifies a dual NAMUR sensor module. NAMUR sensor technology is widely used in process automation for discrete valve position feedback. The selected sensor arrangement must be matched to a compatible input interface and the applicable installation requirements.

Intrinsically Safe Application Options

The StoneL Quartz QN family includes intrinsically safe sensor configurations. In appropriately designed systems, these products may be considered for hazardous-area valve monitoring. However, intrinsically safe operation depends on the complete certified equipment arrangement, including the associated apparatus and installation conditions.

Industrial Enclosure Construction

The Quartz platform offers rugged enclosure configurations for process environments. Manufacturer literature describes corrosion-resistant construction and multiple cover options. Consequently, users can select a configuration appropriate for the environmental conditions of their application, subject to the exact model specification.

Visual Valve Position Indication

Selected Quartz models provide visible open and closed indication. This allows maintenance personnel to inspect valve status locally without relying solely on a remote control display. Indicator colors and mechanical arrangements vary according to the complete ordering reference.

Maintenance and Replacement Support

StoneL QN45CK02HDM and related references may be requested for replacement and maintenance projects. Before purchasing, customers should compare the installed unit’s full part number, actuator mounting arrangement, electrical connection and site requirements.

Industrial Applications

Quartz NAMUR valve monitors are relevant to automated valve systems used in a broad range of process industries. The exact device configuration should always be selected for the operating environment and control architecture.

• Oil and Gas: Automated valve status feedback in production and processing systems.
• Petrochemical: Open and closed position monitoring for process valves.
• Chemical Processing: Valve indication and control system feedback.
• Power Generation: Auxiliary process and utility valve monitoring.
• Water Treatment: Automated valve status supervision.
• Pulp and Paper: Process valve feedback in production equipment.
• Industrial Utilities: Monitoring of pneumatic actuator assemblies.

For hazardous locations, buyers should verify the exact approval markings and relevant installation documentation. A general family description is not a substitute for checking the certification of an individual unit.

How to Select the Correct QN45 Valve Monitor

First, record the complete model number from the existing StoneL nameplate. Next, confirm the required sensor technology and the control system input type. Then, check the enclosure, conduit entries, visual indicator and mounting interface.

For example, the standard QN45C02NRA and QN45C03NRA ordering structures identify different conduit entry arrangements. Likewise, QN45D05NRA and QN45D06NRA identify alternative metric entry configurations. These details can be important when replacing a valve-mounted monitor.

Customers requesting QN45CK02HDM, QN45CR02HRA, QN45K03HDM or QN45K03SDM should provide the original nameplate or purchasing documentation. Additional characters may represent configuration options not fully explained by the standard public ordering table.

Finally, verify QN4XD05HRA separately before including it in a project specification. Its complete sensor designation requires confirmation, so buyers should not assume direct interchangeability with the QN45 models.

Frequently Asked Questions

What is StoneL QN45CK02HDM?

StoneL QN45CK02HDM is a requested Quartz QN45 ordering reference. The QN45 family uses dual NAMUR sensor technology for industrial valve position feedback, while the complete model configuration should be confirmed with manufacturer documentation.

What is the difference between QN45C02NRA and QN45C03NRA?

These standard ordering codes identify different conduit entry arrangements. Buyers should verify the required connection layout before selecting a replacement.

Are QN45D05NRA and QN45D06NRA interchangeable?

Not automatically. Their ordering codes identify different metric conduit entry configurations. Mechanical and electrical compatibility should be confirmed before substitution.

Does the StoneL Quartz QN45 support intrinsically safe applications?

The manufacturer offers intrinsically safe configurations within the QN45 family. Actual installation suitability depends on the specific certification, associated apparatus and applicable installation requirements.

Is QN4XD05HRA the same as QN45D05NRA?

No equivalence has been established. The complete QN4XD05HRA ordering reference requires separate verification before it can be compared with a standard QN45 model.

How can I request pricing and availability?

Send the complete model number, required quantity and delivery destination to Wuhan Yuli Automation. A photograph of the original equipment nameplate can help with model identification.
