German precision and the \u201eMade in Germany\u201d quality guarantee a long service life and consistent performance.<\/p>\n
## Main Features and Advantages<\/p>\n
The KFM_VA models also meet the highest industrial requirements, combining robust design with precise measurement.<\/p>\n
* **Construction:** Fully stainless steel design, providing excellent corrosion resistance.
\n* **Standard:** Complies with EN 837-3 standard.
\n* **Application Area:** Primarily used for measuring gaseous media that do not clog the pressure gauge system (e.g., chemical industry).
\n* **Protection Class:** IP 45 protection, ensuring protection against dust and splashing water.
\n* **Display:** Snap-in design window for easy maintenance.
\n* **Zero Point Adjustment:** The zero point correction can be easily performed using the adjusting screw located on the scale.<\/p>\n

## Detailed Description and Optional Accessories<\/p>\n
The flexibility of the KFM_VA series instruments makes it possible to adapt them to almost any specific measurement task.<\/p>\n
### Accuracy and Calibration<\/p>\n
The basic model offers **Class 1.6 accuracy**, meaning it measures with an error of \u00b11.6% across the full scale length. For applications requiring higher precision, **Class 1.0 accuracy** is also available for an extra charge in the **DS 100** version. The built-in zero-point adjustment screw allows for quick and easy on-site calibration.<\/p>\n
### Connection Options<\/p>\n
The standard connections comply with the most common industrial standards:
\n* **DS 63:** 1\/4″ BSP bels\u0151 menet rozsdamentes ac\u00e9lb\u00f3l (kulcsm\u00e9ret: SW 14).
\n* **DS 100:** 1\/2″ BSP bels\u0151 menet rozsdamentes ac\u00e9lb\u00f3l (kulcsm\u00e9ret: SW 22).<\/p>\n
For special requirements, such as US standard systems, **NPT threads** are also available.<\/p>\n
### Safety Considerations (DS 100)<\/p>\n
For larger diameter instruments of type **DS 100**, additional options are available to enhance safety:<\/p>\n
1. **Laminated Safety Glass:** This option significantly reduces the risk of injury if the instrument's glass is exposed to external impact.
\n2. **BLOW OUT Casing:** This safety feature ensures that in the event of a high-pressure failure, the rear part of the casing intentionally separates, allowing the pressure to safely vent into the space behind the instrument, thereby protecting the operator panel and the user.<\/p>\n
### Custom Solutions<\/p>\n
Leitenberger is committed to meeting individual customer requirements. For the KFM_VA series, the following options are possible:<\/p>\n
* **Custom Scaling:** Application of a logo, special graduation, or differing color coding on the dial.
\n* **For Special Media:** Although the standard version features wetted parts made of copper alloy, completely stainless steel (INOX) wetted parts made from other materials can be ordered for special, aggressive media.<\/p>\n
## Application Areas<\/p>\n
The KFM_VA capsule pressure gauges are excellently suited for the following areas where the measurement of low-pressure gases is required:<\/p>\n
* **Chemical Industry:** Pressure monitoring for reactors, storage tanks, and pipelines.
\n* **Gas Distribution Networks:** Supervision of low-pressure gas transmission systems.
\n* **Laboratory and Research Applications:** Collection of precise, reliable pressure data.
\n* **HVAC and Refrigeration Technology:** Monitoring the pressure of special gases (provided the medium does not damage the copper alloy).<\/p>\n
