Product Description

Kromschroder Differential Pressure Switches Of Air DG50U-3 2.5-50 mbar Gas Control Switch

Application

The gas pressure switch DG monitors extremely low pressure differentials and triggers switch-on, switch-off or switch-over operations if a set switching point is reached. The switching point can be adjusted using a hand wheel. It monitors positive and negative gas pressures on various industrial gas and air appliances, such as boiler fan monitoring and differential pressure monitoring in firing, ventilation and air-conditioning systems. The TÜV-tested special-design pressure switch is used as defined by VdTÜV Code of Practice "Druck 100/1" (Pressure 100/1) in firing installations for steam and hot-water generators in accordance with TRD 604, Para. 3.6.4, as well as class "S" for DG..B, DG..U and DG..I pursuant to EN 1854.

FUNCTION

The pressure switch DG switches in the event of increasing or decreasing pressure. Once the set switching point is reached, a micro switch is activated in the DG which is designed as a change-over contact.

Positive pressure measurement

Positive pressure measurement is designed, for example, for checking the fan function or
measuring the min./max. gas pressure. The positive pressure is measured in the lower diaphragm chamber, port 1 or 2. The upper diaphragm chamber is ventilated via port 3 or 4.

Negative pressure measurement

Negative pressure measurement (air, flue gas) is designed, for example, for monitoring a suction pressure blower. The negative pressure is measured in the upper diaphragm chamber, port 3 or 4, and on DG..T via port 4. The lower diaphragm chamber is ventilated via port 1 or 2. In the case of DG..I,
the negative pressure (gas, air, flue gas or biogas) is measured in the lower diaphragm chamber, port1 or 2. The upper diaphragm chamber is ventilated via port 3 or 4.

Differential pressure measurement

Differential pressure measurement is designed for safeguarding an air flow rate or for monitoring filters and fans, for instance. DG..U, DG..H, DG..N: the higher absolute pressure is connected to port 1 or 2, and the lower absolute pressure to port 3 or 4. The remaining ports must be tightly plugged.
