Kromschroeder (Hokod) DL3A-3 (84444400) Pressure Switch is a high-performance differential pressure control switch widely used in gas, boiler, HVAC, kitchen, and laboratory applications. Here is a detailed introduction to the product:
I. Product Overview
Brand and Model: Kromschroeder (Hokod) DL3A-3 (84444400)
Type: Differential Pressure Control Switch
Origin: Germany
II. Functional Features
Precise Differential Pressure Control: When used for differential pressure control, the DL3A-3 can monitor very small pressure differences, achieving precise differential pressure control. This is particularly important for systems that require fine adjustment of pressure.
Contact Action: When the pressure reaches the set value, the normally open and normally closed contacts inside the pressure switch will actuate, connecting or disconnecting the circuit as needed. This design allows the DL3A-3 to be flexibly applied in various automatic control systems.
Pressure Setpoint Adjustment: The pressure setpoint can be conveniently adjusted using a screw or handwheel. This provides users with great flexibility to set appropriate pressure values based on actual needs.
Multiple Interface Designs:
Interfaces 1 and 2 are connected to the lower chamber of the pressure switch diaphragm for positive pressure control.
Interfaces 3 and 4 are connected to the upper chamber of the pressure switch diaphragm for negative pressure control.
If differential pressure control is used, the high-pressure end is connected to interface 1 or 2, and the low-pressure end is connected to interface 3 or 4. Unused interfaces need to be sealed.
Self-Test Function: In some cases, the DL3A-3 also provides a test button or test interface for self-testing. When the button is pressed (or both buttons are pressed simultaneously for differential pressure control) or the sealing rubber cap of the test interface is removed, the monitored pressure can be released to test whether the pressure switch operates normally.
