KPS 79 060L315066 DANFOSS Heavy-Duty Pressure Switch

Product Overview

The KPS79 060L315066 (060L315066) is a high-performance pressure switch from the Danfoss KPS series, specifically engineered to meet the rigorous demands of marine and heavy industrial sectors. Designed for applications where safety and durability are paramount—such as engine monitoring, steam plant control, and hydraulic systems—the KPS79 060L315066 provides reliable switching under extreme conditions of vibration and shock. This unit utilizes a robust bellows system to actuate a high-load SPDT switch, ensuring precise pressure regulation and alarm functionality. Its heavy-duty construction is optimized to minimize downtime in critical environments, offering long-term setpoint stability and resistance to the corrosive atmospheres typically found in maritime and chemical processing industries.

Technical Configuration

The KPS 79 series is distinguished by its mechanical integrity and specialized internal architecture, built for industrial endurance:

• Bellows Sensing Element: Features a high-grade stainless steel or copper alloy bellows (depending on specific media compatibility), designed to withstand high pressure overloads and rapid pressure cycling without fatigue.

• Vibration Resistance: The internal mechanism is balanced to prevent "contact bounce" or false tripping in high-vibration environments, making it suitable for direct mounting on diesel engines and reciprocating pumps.

• Switching System: Equipped with a Single Pole Double Throw (SPDT) snap-action switch. This configuration allows the unit to function as either a normally open or normally closed contact, providing flexibility for both control and alarm circuits.

• Enclosure Integrity: Housed in a rugged, sea-water resistant enclosure with high ingress protection, ensuring the electrical components remain dry and functional in humid or spray-prone areas.

• Marine Approvals: As part of the KPS line, this model is typically designed to comply with major maritime classifications (such as Lloyd's Register, DNV, and GL), making it a standard choice for onboard machinery.

Technical Specifications

Technical FAQs

How does the KPS 79 handle high-vibration environments compared to standard switches?

The KPS79 060L315066 features a reinforced internal spring and bellows assembly that is specifically tuned to resist mechanical resonance. While standard switches may flutter or fail under the vibration of a marine engine, the KPS series maintains a firm contact force, preventing signal noise and unintended equipment shutdowns.

Is the differential (deadband) on this model adjustable?

Yes, the KPS series generally features an adjustable differential. This allows the operator to set a specific gap between the "cut-in" and "cut-out" pressures, which is essential for preventing "hunting" or rapid cycling in pump control and air compressor applications.

Can this switch be used with sea water?

The KPS 79 is built with a sea-water resistant housing. However, ensure that the wetted parts (the bellows) are compatible with the specific medium. For direct sea water contact, it is often recommended to use a pressure transmitter or a diaphragm seal, though the KPS 79 is highly resilient in maritime engine room atmospheres.

Engineering & Installation Guide

• Mounting Protocol: To maximize the lifespan of the bellows, mount the KPS79 060L315066 on a vertical surface using the integrated mounting holes. For applications involving high-pressure pulsations (such as discharge lines), it is critical to install a damping orifice or a "U" pipe to prevent the bellows from hydraulic shock damage.

• Cable Gland Security: Use only metal Pg 13.5 cable glands to maintain the enclosure's environmental rating. Ensure the cable entry points are facing downwards to prevent moisture from traveling along the cable jacket into the terminal compartment.

• Setpoint Calibration: When adjusting the range and differential, always use a calibrated master gauge. Tighten the locking screws after setting to ensure that industrial vibration does not cause the setpoint to drift over time.
