Danfoss KPS79 060L310566 Pressure Switch and Thermostat

Product Overview

The Danfoss KPS79 (060L310566) is a heavy-duty pressure switch and thermostat combination designed for high-reliability process control in extreme industrial environments. Engineered for durability, this device maintains precise regulation in applications such as steam plants, thermal processing, and maritime pressure systems. Its robust construction ensures long-term operational stability, significantly reducing the maintenance requirements often associated with control components in high-vibration or high-temperature settings. This unit offers an adjustable mechanical differential to match specific process requirements, ensuring consistent performance even under fluctuating thermal loads.

Technical Configuration

The KPS79 series is built for demanding automation tasks where resilience is non-negotiable. The hardware features a specialized sensor mechanism capable of sustained operation at temperatures up to 200 Celsius. The 2-meter capillary tube allows for flexible installation, enabling the controller to be mounted remotely from the sensing point for optimal protection and accessibility. The unit’s architecture is compatible with multiple standard sensor pocket lengths (65 mm, 75 mm, 110 mm, and 160 mm), providing modularity for diverse piping configurations. It is designed to handle rigorous mechanical switching cycles, ensuring that process limits are maintained with high precision.

Technical Specifications

FAQs

Is the differential setting field-adjustable?

Yes, the mechanical differential is adjustable between 4 Celsius and 16 Celsius, allowing for fine-tuning based on specific process tolerance requirements.

Can this unit withstand continuous exposure to 200 Celsius?

The sensor component is rated for a maximum temperature of 200 Celsius, but standard operational settings should remain within the 50 - 100 Celsius range for best performance.

What is the primary function of the capillary tube?

The 2 m capillary tube acts as the thermal transmission medium, allowing for remote installation of the switch body away from the direct process heat source.

Does the 060L310566 include the mounting pocket?

The unit is compatible with various pocket lengths; however, please verify specific accessories separately as the pocket length selection depends on your installation wall thickness.

Installation and Operational Guidelines

• Sensor Pocket Insertion: Ensure the sensor bulb is fully inserted into the thermal pocket to prevent response lag. For best heat transfer, use high-temperature heat-conducting paste inside the pocket.
• Capillary Integrity: Do not bend the capillary tube at a radius smaller than 20 mm. Sharp kinks can cause internal pressure loss or fatigue failure, resulting in inaccurate set-point switching.
• Mounting Orientation: While the KPS series is robust, mount the switch body on a vibration-dampened surface to ensure the internal mechanical snap-action contacts operate within their rated service life. Ensure all electrical connections are properly sealed to maintain the ingress protection rating.
