Description
Product Overview
The HONEYWELL MEASUREX 08690300 is a Disk Drive Assembly supplied with a PIF hard drive, identified as Revision B. It is an industrial computer storage assembly associated with legacy Honeywell Measurex control and measurement equipment.
This type of assembly is typically important in older control systems because the installed drive may contain system software, configuration files, application data, or other system-specific information. For that reason, replacing the complete assembly with a matching part number and revision can be more practical than attempting to substitute a modern commercial hard drive.
The referenced unit is marked 08690300 and Rev B. The current listing identifies it as New – Open Box and states that the item is in excellent new condition with no functional defects.

The available public listing does not provide reliable information for hard-drive capacity, drive interface, spindle speed, controller type, or PIF electrical specifications. These details should therefore be confirmed from the physical label or the customer’s existing system before ordering.
Function
The 08690300 assembly is a dedicated storage component rather than a conventional modern PC hard drive sold as a generic replacement.
In a Measurex installation, the disk assembly may form part of the system’s computing and data-storage architecture. Depending on the host system and software configuration, the drive can contain operating software, application programs, machine configuration information, historical data, or other files required by the installed system.
This makes the exact part number important. A drive with the same physical dimensions but a different controller, interface, formatting, or system image may not provide a functional replacement.
Why the Complete Assembly Matters
For legacy Honeywell Measurex equipment, the storage device is often tied to the original system architecture.
When replacing 08690300, technicians should compare:
- Part number 08690300
- Revision B
- PIF hard-drive configuration
- Connector arrangement
- Drive mounting arrangement
- Interface and cable configuration
- Existing system software requirements
- Drive identification labels
Do not assume that a current SATA, SAS, or IDE commercial drive can be directly substituted without checking the host system.
Installation and Replacement Guide
Before removing the existing disk assembly, shut down the host Measurex equipment according to the applicable system procedure and isolate power where required.
Record the existing drive’s:
- Part number
- Revision
- Manufacturer/model marking
- Cable positions
- Connector orientation
- Mounting position
- Any system-specific identification labels
Handle the assembly carefully and avoid unnecessary exposure to electrostatic discharge.
After installation, verify that all cables are seated correctly and that the drive is mechanically secured. Power up the host system and check whether the controller recognizes the disk before attempting application-level operation.
Data and Software Considerations
A replacement drive is not necessarily equivalent simply because it has the same storage capacity.
Legacy industrial computers can depend on a specific disk image, partition structure, operating system version, controller configuration, or application environment. If the original drive contains system-specific software, preserving the original drive or maintaining a verified backup can be important.
For this reason, the 08690300 assembly should be treated as a system-specific spare rather than as an ordinary consumer hard drive.
Maintenance Recommendations
Disk-drive assemblies in older industrial systems deserve periodic attention because mechanical storage components can degrade even when the host controller remains operational.
Recommended checks include:
- Check for unusual drive noise.
- Monitor system boot or access errors.
- Check cables and connectors for oxidation or looseness.
- Keep cabinet temperature and airflow within the host system’s requirements.
- Maintain a verified backup of important system data.
- Avoid unnecessary power cycling of aging mechanical drives.
- Record the installed part number and revision for future procurement.
If a system is still operating with an original legacy drive, creating a validated backup or spare strategy can reduce downtime when the drive eventually fails.
Replacement Compatibility
The preferred replacement is another Honeywell Measurex 08690300 Rev B assembly with the same PIF hard-drive configuration.
Before purchasing an alternative revision, confirm:
| Check Item | Requirement |
|---|---|
| Part Number | 08690300 |
| Revision | Rev B preferred |
| Assembly Type | Disk Drive Assy |
| Drive Configuration | W/PIF Hard Drive |
| Mechanical Fit | Must match host equipment |
| Electrical Interface | Must match original |
| Software/Image | Must be compatible with host system |
| Connectors | Must match existing installation |
A different Honeywell Measurex disk assembly should not be treated as a direct replacement solely because it belongs to the same product family.
Applications
The 08690300 assembly is intended for legacy Honeywell Measurex industrial computing and measurement environments.
Potential applications include:
- Industrial measurement systems
- Process monitoring
- Web inspection systems
- Manufacturing control equipment
- Industrial computer systems
- Legacy Honeywell Measurex installations
- Replacement-spare inventories for discontinued equipment
Inspection Before Shipment
For a 08690300 assembly, a useful pre-shipment inspection should include:
- Confirm 08690300 part number.
- Verify Rev B marking.
- Photograph the identification label.
- Check the physical housing and mounting points.
- Inspect connectors and cables.
- Check for corrosion or mechanical damage.
- Verify that the hard-drive assembly is present.
- Where appropriate, perform a controlled power-up or system recognition test.
- Package the drive with suitable anti-static and mechanical protection.
The referenced listing identifies the unit as New – Open Box rather than factory-sealed new, so the actual packaging and accessories should be confirmed before shipment.
