Pressure switch Dungs UB 50 A2

Pressure relay Dungs UB 50 A2 article 215242 is a compact device for monitoring excess pressure / vacuum pressure in gas pipeline systems, where any pressure fluctuations are critical. Characterized by ease of adjustment, uninterrupted service, reliable performance. Comply with EN 1854. The scope of application is combustion devices of a wide range of manufacturers.

Characteristics

• Maximum pressure: 500 mbar.

• Setting range: 2.5-50 mbar.

• Gas: 1-3 families / neutral.

• Operating temperature: -15 ° C to + 70 ° C.

How it works

The sensor-relay switch reacts to excess pressure. The device does not require external energy to perform its functions. When the permissible pressure value is exceeded, the contact is switched on, switched off, switched and a signal is transmitted to the control unit. In this case, the relay is blocked. The indicator light indicates that the device is locked. To unlock, press the reset button located in the central part of the adjustment wheel.

Design and installation features

The switching point is set by rotating a special disk. A digital scale is provided to simplify adjustment. No need to use a pressure gauge.

The reliable device is made of cast aluminum (housing), NBC (membrane), polyamide (switch). The contact material is silver. The outer shell meets the requirements of IP54 electrical protection according to IEC 529. Electrical connection - via a PG cable entry.

Connection to the system is carried out via a sealing ring, on Dungs fittings. In the standard installation position, the maximum pressure limiter is triggered taking into account the settings. When installed horizontally, inverted or in an intermediate position, switching occurs at a higher/lower pressure relative to the set values.

Advantages:

• suitable for burners of most brands;

• easy adjustment of parameters using the regulator;

• blocking when triggered;

• reliable protection against dust/splashes (class IP 54);

• easy installation in the system;

• indication of the locked position;

• compact design.
