Реле давления Kromschroder DL1.5A-3. Kromschroder DL1.5A-3 Pressure Switch

Kromschroder DL1.5A-3Z pressure switch, art: 84444411 is integrated into air and non-aggressive gas pressure control and regulation systems, closing, opening and switching contacts when the pressure reaches the set switching point. Adjustment is made manually by turning the dial. The membrane sensor is characterized by reliable operation due to the use of gas-tight materials and a robust design.

Features:

• purpose – control of differential, overpressure, vacuum pressure;
• medium – air, flue gases and other non-aggressive gases;
• control of extremely low pressure drop;
• possibility of checking the switching status by indication;
• electrical connection through threaded terminals; 
• sensor with threaded connection Rp ¼" and pipe connection with handwheel (optionally Rp 1/8");
• installation vertically (recommended) or horizontally, not downwards with the external side;
• degree of protection of electrical components against dust and moisture IP 54;
• membrane sensor type;
• plastic housing with fiberglass reinforcement;
• low gas permeability;
• maximum medium pressure – 50 mbar;
• membrane made of NBR;
• ambient and operating temperature from -20 to +80 °C.

Application 

The Kromschroder DL pressure switch is used in gas-burning installations as an element of the automatic control system for the disc damper for air supply, fire dampers, for monitoring the operation of the fan, draft in chimneys, etc.
