KPS80 060L313066 Danfoss High-Performance Industrial Temperature Switch

Product Overview

The KPS80 060L313066 (KPS80 060L313066) is a heavy-duty industrial thermostat from the renowned KPS series, specifically engineered to meet the rigorous demands of marine and heavy-industry sectors. Designed for applications where reliability and precision are non-negotiable—such as engine cooling systems, oil lubrication monitoring, and industrial boiler control—this switch excels in environments prone to high vibration and mechanical shock. The KPS80 060L313066 features a robust contact system with high-level functional safety, ensuring critical alarm or control signals are triggered accurately even under extreme conditions. With its expansive 5-meter capillary tube, this unit provides maximum installation flexibility, allowing the sensor to be placed in high-temperature zones while the switch housing remains in a protected, accessible location.

Technical Configuration

The KPS80 060L313066 operates as a temperature-controlled switch with a wide setting range of 70 to 120 deg C. It incorporates an adjustable mechanical differential (hysteresis) ranging from 4.5 to 18 deg C, providing engineers with the ability to fine-tune the switching points to prevent rapid cycling and system wear. The hardware architecture includes a durable bellows system designed to withstand sensor temperatures up to 220 deg C, offering a significant safety margin for process overshoots. The 5-meter copper capillary tube enables remote sensing, while the switch housing is built to withstand the harsh vibrations found on ship decks or near large reciprocating compressors. The unit is compatible with standard 110 mm and 160 mm sensor pockets, facilitating easy integration into pressurized thermowells.

Technical Specifications

Technical FAQs

Can the KPS80 be installed in marine engine rooms?

Yes, the KPS series is specifically designed and approved for marine use. Its high resistance to vibration and shock makes it ideal for mounting directly on or near marine diesel engines and propulsion systems.

What is the advantage of the adjustable differential in this model?

The adjustable differential (4.5 to 18 deg C) allows you to define the gap between the "cut-in" and "cut-out" temperatures. This is vital in cooling systems to prevent the fan or pump from turning on and off too frequently, which extends the lifespan of the associated motor and contactors.

Is the capillary tube protected against corrosion?

The capillary tube is high-quality copper. In environments with aggressive chemicals or seawater, it is highly recommended to use the sensor with a stainless steel or brass sensor pocket (thermowell) to ensure long-term durability.

Does this unit require a specific mounting orientation?

The KPS80 is generally insensitive to mounting position. However, it is best practice to mount the housing so that the cable entry points downward to prevent moisture ingress, maintaining the integrity of the IP67 seal.

Engineering & Installation Guide

• Capillary Tube Management: When routing the 5-meter capillary tube, avoid sharp bends or kinks. A minimum bending radius of 25 mm should be maintained. Ensure the tube is supported along its length to prevent vibration-induced fatigue, and never cut or shorten the capillary, as it is a sealed system containing the thermal charge.

• Sensor Pocket Installation: For accurate temperature response, ensure the sensor bulb is fully inserted into the 110 mm or 160 mm pocket. Use a thermal conductive paste inside the pocket to eliminate air gaps and reduce the thermal time constant, ensuring the switch reacts quickly to temperature fluctuations in the medium.

• Electrical Connection & Safety: Use flexible conduit for electrical entry to maintain the vibration-resistant properties of the installation. Ensure all connections are tightened to the specified torque. For safety-critical applications (e.g., engine overheat), the SPDT contact should be wired to a fail-safe logic circuit where a wire break or power loss triggers an alarm.
