Product Description

Germany Kromschroder OR DG500H-3 Air Compressor Furnace Pressure Switch For Industrial Gas Burner

TECHNICAL INFORMATION

• Monitoring of gas and air pressures (positive, negative and differential pressures)

• Certified for systems up to SIL 3 and PL e
• With approved isolating amplifier for Zone 1 and 2 hazardous areas

• EU certified pursuant to EN 1854 and class “S”

• DG..S: special version available for NH3 and O2

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.

Pressure switches with manual reset lock off after switching. Pressure switches (DG..T) with UL, FM approval are fitted with a nozzle to limit the flow rate, see page 11 (Vent limiter).

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 switches with rising or falling pressure. Once the set switching point is reached, a micro switch is activated
in the DG which is designed as a change-over contact. The switching pressure is adjusted using a hand wheel. Pressure switches
which lock off after switching can only be unlocked with a manual reset, see page 24 (Resetting pressure switches with manual
reset).

3.1 Vent limiter

The flow on pressure switches DG 6..T to DG 500..T is limited by the nozzle. In the event of a diaphragm tear, the escape of gas is limited to less than 1.0 CFH of natural gas, see max. inlet pressure, see page 28 (Technical data).

3.2 Positive pressure measurement

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

3.3 Negative pressure measurement

Negative pressure measurement (air, flue gas) is designed, for example, for monitoring a suction
pressure blower. 4 3 1 2 Air, flue gas The negative pressure is measured in the upper diaphragm chamber, port4 (or 3). 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, port 1 or 2. The upper diaphragm chamber is ventilated via port 4 or 3.
