Danfoss 060L312866 KPS80 Temperature Control

Product Overview

The Danfoss 060L312866 (KPS80) is a high-performance, robust temperature control switch designed to maintain strict thermal regulation in severe industrial environments. Built for longevity in applications such as power generation, heating systems, and maritime engine rooms, this unit features a durable armoring and an adsorption-charge sensing element. By offering precise SPDT gold-contact switching, it ensures reliable signal transmission and long-term stability even in environments prone to high vibration or mechanical shock. Its ability to withstand extreme ambient temperatures, from -40 Celsius up to 70 Celsius, makes it a critical component for preventing thermal runaway and minimizing downtime in mission-critical process loops.

Technical Configuration

The 060L312866 KPS80 series is configured with a 2000 mm capillary tube, providing flexibility for remote sensor placement within complex machinery layouts. The connection interface features a standard M 18 x 1.5 thread for pocket or hose integration, ensuring a secure seal. This model utilizes an adjustable differential, ranging from 4.5 K to 18 K, allowing engineers to fine-tune the switching behavior to the specific requirements of the thermal process. Electrical termination is handled via a Pg 13.5 screwed cable entry with a metal gland, ensuring superior mechanical protection and ingress prevention for the internal connections.

Technical Specifications

FAQs

What is the advantage of using SPDT gold contacts in this controller?

Gold-plated contacts are optimized for low-current applications (1 to 30 mA), ensuring reliable electrical contact and preventing the formation of oxide layers that can cause signal failure in low-voltage logic circuits.

Can the KPS80 be installed in high-vibration areas?

Yes, the KPS80 series is specifically designed for high-vibration resilience. The armored capillary tube further protects the sensing line from external mechanical damage during operation.

How does the adsorption charge improve performance?

The adsorption charge type provides a stable and predictable response across the temperature range, ensuring high accuracy in switching points even when ambient temperatures fluctuate.

What is the purpose of the M 18 x 1.5 connection?

This connection is designed for mounting the sensor bulb into a thermowell (pocket), which protects the sensing element from direct contact with aggressive or high-pressure process media.

Installation and Operational Guidelines

• Sensor Bulb Placement: For accurate temperature readings, ensure the sensor bulb is fully immersed in the medium. If using a thermowell, ensure there is thermal conductive paste present to minimize response time lags between the process media and the sensing element.
• Cable Gland Integrity: When wiring the Pg 13.5 gland, ensure the cable outer diameter is properly matched to the gland seal. An improperly tightened gland will compromise the device’s ability to prevent dust and moisture ingress, which can lead to premature contact degradation.
• Differential Adjustment: When adjusting the differential, turn the setting knob slowly and verify the actual switching point with an external calibrated thermometer. The differential must be adjusted within the 4.5 K to 18 K range to ensure the control loop does not chatter or hunt during normal operation.
