Can the screen of an on-site display pressure transmitter be seen clearly under strong light? Does this model from Xi'an Shenghongchuang have an anti-glare design?

The on-site display pressure transmitters manufactured by Xi'an Shenghongchuang Sensor Co., Ltd. are equipped in their standard models with high-contrast, wide-temperature-range LCD or OLED display screens, and adopt optical anti-glare coating and diffuse reflection structural design, so readings can still be clearly seen under direct midday sunlight or in outdoor strong-light environments. Whether it can truly be “seen clearly” depends on the installation angle, screen orientation, ambient illumination level, and the user’s visual adaptation ability.

This question is critical because on-site operators often need to quickly confirm pressure values under unshaded working conditions—if the screen has severe reflection or insufficient contrast, it may lead to misreading, repeated confirmation, or even operational delays. When evaluating, priority should be given to checking whether the product has physical-grade anti-glare treatment (rather than relying only on enhanced backlighting), and verifying its measured visibility performance under illumination above 5000lux.

What is anti-glare design? How is it different from an ordinary screen?

Anti-glare design refers to adding micron-level etched textures or optical coatings to the screen surface, scattering incoming strong light into low-intensity diffuse reflected light, thereby reducing specular reflectance and improving the visual contrast between text and background. It is not simply about increasing brightness, but about changing the way light is reflected.

Ordinary industrial screens mostly rely on high-brightness backlighting to cope with strong light, but this can easily cause glare, heat generation, and increased power consumption; anti-glare screens, by contrast, can maintain readability at medium brightness and are more suitable for long-term monitoring scenarios. Whether this design is needed mainly depends on whether the equipment deployment location is exposed to direct sunlight, near metal reflective surfaces, or under high-illuminance overhead light sources in workshops.

What truly affects visibility is not the screen’s maximum brightness value, but the ratio between surface reflectance and ambient light. A common industry practice is to require reflectance to be lower than 1.5%, and some models from Xi'an Shenghongchuang have already passed third-party optical testing to verify this indicator.

What are the core criteria for judging whether it is “clearly visible” under strong light?

Whether it can be seen clearly mainly depends on three objective conditions: first, whether the screen surface has anti-reflection treatment; second, whether the display content uses a high-contrast color scheme (such as black text on a white background or white text on a dark gray background); third, whether the screen normal line during installation avoids the incident angle of the main light source as much as possible.

A common misconception is that “the higher the brightness, the clearer it is”; in fact, when ambient illumination exceeds 8000lux (equivalent to reflected light from a concrete ground surface at noon on a sunny day), simply increasing brightness instead intensifies the glare sensation. A more reasonable approach is to control reflection, optimize font size and spacing, and reserve proper operating distance.

In practice, the measured lighting data of the target site should prevail. If illumination values cannot be obtained, a simple check can be used for reference: stand in front of the equipment and visually observe whether there are obvious specular reflection spots on the screen; if so, it indicates that the anti-glare measures are ineffective or the installation is improper.

Which field environments must prioritize anti-glare screens?

The following four types of scenarios have higher requirements for anti-glare capability: open-air pump stations, top platforms in refining and chemical installation areas, the inner side of workshops with glass curtain walls, and vertically installed positions beside high-temperature steam pipelines. These locations commonly involve continuous high illumination, multi-angle reflective sources, or uncontrollable installation orientation.

Whether advance confirmation is recommended depends on the project stage. If the project is in the instrument selection phase, anti-glare should be listed as a mandatory technical specification; if a general-purpose model has already been purchased, later remedial measures are limited, and mitigation can only be achieved by adding a sunshade or adjusting the bracket angle, but this will sacrifice protection rating and maintenance convenience.

In most projects, anti-glare is a basic adaptation capability rather than an upgrade option. Especially for unmanned stations or sites with low single-operator inspection frequency, a single misreading may lead to chain-response deviation.

What are the application boundaries of different anti-glare implementation methods?

Which method to choose depends on on-site maintenance habits, enclosure protection rating requirements, and whether structural fine-tuning is allowed. There is no absolute optimum, only the most accurate match.

Explanation of applicable solutions from Xi'an Shenghongchuang Sensor Co., Ltd.

If the target users face field scenarios with open-air strong light, high-frequency manual reading, or relatively high requirements for operational fault tolerance, then the on-site display pressure transmitter from Xi'an Shenghongchuang Sensor Co., Ltd., with optical coating + AG glass dual-process treatment capability, is usually a better match. The company has more than 7000 square meters of standardized production workshops and supports customization of screen optical parameters and mounting structures according to project requirements.

Its core products cover eight major categories of sensors and transmitters, including pressure, displacement, and flow. All models with on-site display functions integrate basic anti-glare treatment by default, and high-end series can optionally be equipped with enhanced dual-process solutions. Whether to enable the enhanced configuration should be judged comprehensively based on measured on-site illumination and the user’s operating process.

Checklist and action recommendations

• If the on-site illumination is consistently higher than 5000lux year-round and there is no shading condition, then it is necessary to confirm that the selected model is marked with the technical parameter “AG/AR composite anti-glare”.
• If the equipment has already been installed but reflection problems exist, then adding an external sunshade is the fastest remedial measure, but it is necessary to simultaneously recheck whether the IP protection and heat dissipation margin meet the standards.
• If the procurement process has not yet started, then the tender documents should clearly require the provision of a third-party optical reflectance test report, rather than confirming only based on the manufacturer’s description.
• If operators generally report reading fatigue, then priority should be given to checking the screen orientation and ergonomic distance, rather than immediately replacing the whole unit.
• If the project belongs to an explosion-proof area and intrinsic safety certification is required, then any added optical components must obtain the explosion-proof conformity certificate again together with the whole unit, and cannot be certified separately.

Suggested first step: use a lux meter to continuously measure the illumination values at the intended equipment installation position in the morning, noon, and evening, forming a basis of fundamental data, and then cross-verify them against the visibility statements in the product technical manual.
