APPLICATION / FEATURES
The COMBUPx compact pressure switch is specially designed for monitoring air or gas pressure in gas-fired
equipment and systems, such as burners.
• It allows for effective monitoring of pressure in gas pipelines. • Its compact size makes it very easy
to install, even in confined spaces. • Thanks to its ergonomic structure, the user can adjust the operating
parameters himself. • It is available in several versions, offering different pressure settings to suit
various installation needs.
• COMBUPx can be configured as minimum or maximum pressure switches,
depending on system requirements.
• The set point is adjustable up to 500 mbar, independent of the range
effective.
• It can operate under a continuous working pressure of up to 600 mbar. • It is
compatible with gases of families 1, 2 and 3, as well as with other neutral gases
non-corrosive.
• Fully compatible with other similar products, it integrates easily into existing systems.

Noticed
In the following cases, we recommend that you contact us before use.
1. Use only sufficiently cured silicone tubes.
2. Vapors containing silicone may impair the operation of electrical contacts. In case of low switching capacities, e.g. 24 V, less than 20 mA, we recommend using an RC module or an electronic switch
(non-contact switch) in air containing silicone or oil.
3. A fall or impact may compromise the safety functions. These products must not be put into service, even if they show no damage.
4. In case of high humidity or aggressive gaseous components (H2S), we recommend using a pressure switch with gold contact.
5. Closed-circuit current monitoring is recommended under severe operating conditions.
6. Do not operate at a pressure lower than the minimum set pressure.

Installation position
Standard installation position
If a different installation position is used, be careful
at modified operating points
When installed horizontally, the pressure switch switches to the
highest pressure.
When installed horizontally above the head, the
pressure switch switches to the lowest pressure.
When installed in an installation position
intermediate, the pressure switch switches to the highest pressure
high.
