PRECISE DIFFERENTIAL PRESSURE MEASUREMENT FOR ULTRA-LOW PRESSURES CUSTOMIZED TO YOUR SPECIFICATIONS – MEASUREMENT RANGE UP TO ±1800 PASCAL (±18 MBAR)
Robust | Long-Term Accuracy | Maintenance-Free | Largely Wear-Free
CUSTOMIZABLE CONFIGURATION
Specify the measurement range, unit, and supply voltage according to your needs when placing your order. This ensures you receive a product that is perfectly tailored to your requirements.
RESISTANT TO AGGRESSIVE MEDIA
The measured media only come into contact with resistant materials within the device, preventing damage from aggressive gases.
LARGELY WEAR-FREE
High-precision ball bearings are used in the devices, minimizing wear in the mechanics and thus in the measuring mechanism.
MAINTENANCE-FREE
A ring scale is designed to require neither maintenance nor recalibration.
LONG-TERM ACCURACY
Instead of a measurement spring, the “calibration weight” determines the calibration. A weight cannot age or be overstretched due to overload.
Ensures accuracy even at very low pressures.
DAMPING BEHAVIOR
The rotation of the ring body and the liquid contained within it create a damping effect during measurement.

WHAT MAKES RIXEN’S MEASURING INSTRUMENTS STAND OUT?
The Unique Measuring Principle: The Ringbalance.
Our innovative ring scale uses a calibration weight instead of a traditional measuring spring, offering numerous advantages:
- Durability: No aging or wear, as the calibration weight has no “memory effect.”
- Reliable Zero Point: Always returns to zero, even after prolonged load.
- Smooth Needle Movement: Due to the volume and weight of the ring body.
- Precise Measurement of Small Pressures: Measurement ranges of -20…0…+20 Pa or -10…0…+40 Pa.
- Custom Manufacturing: Each ring scale is handcrafted and calibrated to customer specifications.
MAKING PRESSURE FLUCTUATIONS VISIBLE
Thanks to the generous 150×150 mm scale, pressure fluctuations are clearly visible. This allows for precise assessment of the dynamic behavior in pressure regulation.
- Generous Scale: 150×150 mm for clear visibility.
- Precise Assessment: Accurately analyze the dynamic behavior of pressure regulation.
- Easy Readability: The large scale facilitates reading even from a distance.
- Reduced Error Rate: Clearly visible measurements minimize the risk of reading errors.
Our measuring instruments provide the necessary precision and visibility for demanding applications.
MEASUREMENT RANGES CUSTOMIZED TO YOUR SYSTEM
Our measuring instruments cover a wide range to perfectly fit your specific system:
- Low Pressure Range: Ideal for furnace rooms or clean rooms with ranges like -20/0/+20 Pa or -10/0/+40 Pa.
- High Pressure Range: Suitable for applications like flue gas extraction, drying, and ventilation systems up to 1,800 Pa.
- Flexible Intermediate Values: All intermediate values possible, including:
- -100/0/+100 Pa
- -150/0/+50 Pa
- 0…-600 Pa
- 0…-1000 Pa
- Reliable Accuracy: All versions guarantee an accuracy of +/-1.5% or 1.5 Pa.
LONG-TERM ACCURATE MEASUREMENT OF VERY LOW PRESSURES
Our measuring instruments are not only designed for long-lasting use, but also specifically for the precise measurement of very low pressures.
Robust materials for reliable use:
Housing: made of polycarbonate and fibreglass, it can withstand even the most aggressive gases and polluted air.
Measuring mechanism: Made of brass, it offers a robust and durable measuring solution.
Ring scale – the heart of the system:
Long-term testing: thanks to the use of a calibration weight that does not age or change, the ring scale always returns to the set zero point.
Constant accuracy: No springs or diaphragms that could change shape, for lasting precision.
We therefore offer you a measuring solution that is robust, reliable and remains accurate in the long term.
DURABILITY AND REPLACEMENT WITH NEW DEVICES
Replacement appliances: Using the old appliance number alone, we can easily determine the exact version and offer a fully compatible replacement appliance. The existing wall holes remain usable thanks to a mounting adapter.

Flexibility in application: Depending on the connection assignment, each device can be used as a differential pressure gauge, tension gauge or pressure gauge to meet your specific requirements.
| Conversions of pressure units | |||
| Pa | mbar | mmWs | |
| 1 Pa = | 1 | 0,01 | 0,102 |
| 1 mbar = | 100 | 1 | 10,2 |
| 1 mmWs = | 9,81 | 0,098 | 1 |
OVERLOAD CAPACITY INDEPENDENT OF THE MEASURING RANGE
The overload capacity of our measuring devices depends solely on the sealing liquid used, not on the specified measuring range.
Example: A ring scale with a measuring range of ±20 Pa (filled with the sealing liquid filling oil) tolerates a permanent overload of up to ±700 Pa without damage. This ensures the integrity of the measuring mechanism and the reliability of the calibration.
For more extreme conditions:
For expected overloads above 700 Pa with filling oil
or over 1.8 kPa when using Galden
we recommend installing an overload protection device to ensure long-lasting and safe operation.
CERTIFICATION
For applications in potentially explosive atmospheres, we offer devices that are certified in accordance with the ATEX Manufacturer’s Directive 2014/34/EU to ensure the highest safety standards.
Furthermore, we are aware of the importance of continuous quality improvement and therefore work strictly in accordance with the requirements of ISO9001:2015. This commitment to quality is underlined by our certification from the renowned Deutsche Qualitätsmanagement Akademie GmbH, which has successfully certified our company in accordance with this internationally recognised standard for many years.
