The Leitenberger KFM_VA series capsule pressure gauges feature excellent quality, all stainless steel construction, and are specifically optimized for measuring gaseous media that do not cause clogging in the pressure gauge system. These instruments offer an ideal solution for the chemical industry and other areas where reliable, precise pressure measurement is required. German precision and the „Made in Germany” quality guarantee a long service life and consistent performance.
The KFM_VA models also meet the highest industrial requirements, combining robust design with precise measurement.
Construction: Fully stainless steel design, which ensures excellent corrosion resistance.
Szabvány: Complies with EN 837-3 standard.
Area of application: Primarily intended for measuring gaseous media that do not clog the pressure measuring system (e.g., chemical industry).
Protection Class: IP 45 protection, which ensures protection against dust and splashing water.
Display: Snap-in window design, which allows for easy maintenance.
Zero Point Adjustment: Zero point correction can be easily performed using the adjustment screw found on the scale.

The flexibility of the KFM_VA series instruments makes it possible to adapt them to almost any specific measurement task.
The basic model offers a 1.6 accuracy class which means the full scale length measures with an error of ±1.6%. For applications requiring higher precision, the DS 100 is available in a version for an additional charge with a 1.0 accuracy class as well. The built-in zero-point adjustment screw allows for quick and easy calibration on site.
The standard connections comply with the most common industrial standards:
DS 63: 1/4″ BSP female thread made of stainless steel (wrench size: SW 14).
DS 100: 1/2″ BSP female thread made of stainless steel (wrench size: SW 22).
For special requirements, such as for American standard systems, NPT threads are also available.
For larger diameter, DS 100 type instruments, additional options are available to increase safety:
Laminated Safety Glass: This option significantly reduces the risk of injury if the instrument glass is exposed to external impact.
BLOW OUT Back Casing: This safety feature ensures that in case of a high-pressure failure, the rear part of the casing intentionally separates, and the pressure safely vents into the space behind the instrument, thereby protecting the operator panel and the user.
Leitenberger is committed to meeting individual customer requirements. For the KFM_VA series, the following options are possible:
For Custom Scaling: Use of logo, special graduation or differential coloring on the gauge face.
For Special Media: Although the standard version has bronze alloy contact parts, fully stainless steel (INOX) contact parts made from other materials are also available for special, aggressive media.
The KFM_VA capsule pressure gauges are excellently suited for the following areas where the measurement of low-pressure gases is required:
Chemical Industry: Monitoring the pressure in reactors, storage tanks, and pipelines.
Gas Distribution Networks: Supervision of low-pressure gas transport systems.
Laboratory and Research Applications: Collection of precise, reliable pressure data.
Air conditioning and Refrigeration Technology: Monitoring the pressure of special gases (provided the medium does not damage the bronze alloy).
The KFM_VA series represents Leitenberger quality, ensuring accurate and safe pressure measurement even in the most demanding industrial environments.
