DG Series

Kromschroder DG Pressure Switches for Air and Gas Pressures

Featuring the ability to observe extremely low pressure differentials, Kromschroder's DG pressure switches trigger switch-on, switch-off, switch-over operations if a set switching point is reached. They monitor positive and negative gas and air pressures in industrial and commercial applications.

Key Specifications

· Applications in monitoring positive air and gas pressures, negative or differential air pressures

· Five pressure ranges from 0.2" to 200" WC (0.5 m bar to 500 m bar)

· Accurate, repeatable switching action with low hysteresis

· Automatic and manual reset models available

· One normally open and one normally closed contact in each switch (5A resistive or 0.5A inductive)

· 8A quick-acting fuse for short circuit protection

· FM and UL approved

Madas gas pressure switches are primarily represented by the PSM series. These are compact diaphragm pressure switches used to monitor gas or air pressure and trigger an electrical circuit (making or breaking contact) when pressure crosses a set point.

They are widely used in gas trains, industrial burners, and boiler systems for safety interlocks.

The model number indicates the maximum end of the adjustable pressure range in mbar.

•  Media: Natural Gas, LPG (non-aggressive dry gases), and Air.

• Electrical Rating: * Voltage: 24V to 250V AC / 24V to 48VDC.

  •  Current: Max 6 A (resistive) / 2 A (inductive).

    Protection Class: IP54 (Standard protection against dust and water splashes).

• Connection: Standard G 1/4" female central thread (Side connections available on request).

The switch uses a standard 3-pin DIN connector (EN 175 301-803).

• Pin 1 (COM): Common 

• Pin 2 (NC): Normally Closed (opens on pressure rise)

• Pin 3 (NO): Normally Open (closes on pressure rise)

Dungs is a leading manufacturer of pressure switches for gas and air, primarily used in industrial burners and HVAC systems. Their models are categorized by how they connect and what they monitor (overpressure, vacuum, or differential pressure).

While specific to the model, these are the typical operating parameters for the Dungs range:

• Maximum Operating Pressure :

  • Standard models (GW/LGW): 500 mbar to 600mbar.

  • High-pressure models (GW...A4 HP): Up to 2, 5, or 8 bar.

• Temperature Range: -15 C to +70°C (Some variants rated for lower ambient temps).

• Protection Class: Typically IP54 as standard, with IP65 available for outdoor/harsh environments.

• Electrical Connection: 3-pin plug connection (DIN EN 175 301-803) or screw terminals.

• Materials: Aluminum die-cast housing with NBR rubber diaphragms.

The alphanumeric suffix at the end of a model (e.g., GW 50 A6) tells you how it connects to your system:

• A2: O-ring flange connection, often used for direct mounting on Dungs Multiblocs or DMV valves.

• A4: Threaded connection (typically 1/4" NPT or ISO) with a hand-wheel for manual adjustment.

• A5: Compact version for Multiblocs/DMV valves.

• A6: Compact version with a 1/4" threaded connection and an integrated test nipple.
