Gauge Glass
Gauge/sight glass
Recommended route in the application record
Gauge Glass appears in the V4.1 recommended material route for Protective Glass Cover, but the exact grade and assembly conditions still require validation.
Drawing and system validation
The material name does not certify the installed equipment. Grade, thickness, edge, surface, coating, mounting and service-condition validation remain project-specific.
Application Conditions That Control Material Selection
Optical, thermal, chemical, mechanical, pressure, sealing and cleaning requirements must be defined before this material route is accepted.
| Service condition | What to define |
|---|---|
| Optical or viewing requirement | Define whether the window is for human viewing, imaging, ranging or barcode reading. |
| Temperature and thermal cycling | Cabinet heat and washdown temperature cycling must be considered. |
| Chemical and cleaning exposure | Coolant mist, oils, detergents and dust may attack coating or obscure sensors. |
| Mechanical and mounting load | Vibration, door slam, guard load and fastener/clamp stress require safe mounting. |
| Pressure or vacuum boundary | Protective Equipment Window: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Use hazard-compatible cleaning that preserves hard/AR coatings; inspect for impact damage, scratches and edge cracks before return to service. |
Gauge Glass for Protective Glass Cover
The V4.1 application route and the selected material record are shown separately so an unsupported combination is not presented as automatically approved.
| Decision area | Application and material basis |
|---|---|
| Compatibility status | Recommended route in the application record. Gauge Glass appears in the V4.1 recommended material route for Protective Glass Cover, but the exact grade and assembly conditions still require validation. |
| Application recommended route | Borosilicate/low-iron for observation, optical/filter glass for sensors, strengthened aluminosilicate for exposed HMI covers. |
| Application alternatives | Sapphire for severe abrasion/impact, strengthened aluminosilicate for lighter covers, or borosilicate for thermal/chemical observation. |
| Selected material capability | Liquid-level gauges and process observation |
| Selected material limitations | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Selection evidence required | Document why Gauge Glass is chosen for Protective Glass Cover, including rejected alternatives and the validation method. |
| Selected material property | Published reference |
|---|---|
| Material category | Gauge/sight glass |
| Chemical resistance | Acid class 1 reported by the reviewed DIN 7081 manufacturer datasheet |
| Available forms | Oblong transparent or reflex gauge-glass plates |
Drawing, Processing and Assembly Definition
Phase 6I does not import generic process capability numbers. Manufacturing and acceptance remain tied to the exact grade, geometry, quantity and drawing.
| Route item | Project-specific requirement |
|---|---|
| Typical component forms | Sensor window, machine-vision window, observation panel, scanner cover or HMI cover. |
| Application process route | CNC cutting/drilling, edge safety finish, optical polishing/coating where sensed, printing and clean assembly packing. |
| Material-compatible processes | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Size and thickness | Housing and guard load determine size; use drawing-specific mechanical analysis rather than a generic window thickness. |
| Edge and surface zones | Safe exposed edges; low-distortion/low-scatter faces only where sensing demands them. |
| Drawing release | For Protective Glass Cover glass processing for Gauge Glass, identify exact grade, datums, clear aperture, mounting and sealing lands, edge profile, surface quality, coatings, quantity, inspection and packaging. |
Quality Controls for Protective Glass Cover glass processing for Gauge Glass
Inspection must verify both the material-dependent characteristics and the installed application requirement.
| Risk or control | Application × material focus |
|---|---|
| Application failure modes | Sensor dropout, contamination, clamp fracture, coating wear, glare and maintenance damage. |
| Material-specific limits | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Inspection method | Dimensions/edge, optical function with the sensor, vibration/cleaning cycles and fixture fit. |
| Standards and system validation | The finished equipment protection standard is selected by hazard and market; ISO 10110 applies only to optical characteristics. |
| First article | For Protective Glass Cover glass processing for Gauge Glass, validate fit, optical or viewing performance, mounting, cleaning and the most critical service condition before batch release. |
| Traceability and packaging | State grade certificate, lot, inspection report, coating side, cleanliness, edge protection and packaging requirements. |
