KPS 80 060L315666 Contrôle de température DANFOSS 70 à 120 °C

Product Overview

The 060L315666 (060L315666) is a heavy-duty KPS 80 series temperature switch designed by Danfoss for demanding industrial and marine applications. Featuring a robust adsorption charge sensing system, this controller operates within a 70 to 120 deg C range, providing reliable thermostat functionality in engine rooms, power plants, and chemical processing facilities. The 060L315666 is engineered to withstand high vibration and harsh environmental conditions, utilizing a 3000 mm armored capillary tube to allow for flexible sensor placement while protecting the internal hydraulic circuit. By employing high-quality SPDT gold-plated contacts, this unit ensures fail-safe switching for both high-power loads and low-voltage PLC signals, significantly enhancing system safety and preventing thermal runaway in critical machinery.

Technical Configuration

The KPS 80 series is distinguished by its mechanical durability and precision adjustment capabilities, specifically configured for industrial endurance:

• Sensing Element: Utilizes an adsorption charge principle, which offers high resistance to ambient temperature fluctuations and ensures the setpoint remains stable even when the housing is exposed to varying conditions.

• Armored Capillary: Features a 3000 mm (118 1/8 in) armored capillary tube, providing mechanical protection against abrasion, kinking, and impact in heavy-duty industrial settings.

• Switching Mechanism: Equipped with an SPDT (Single Pole Double Throw) contact system with gold plating, making it compatible with low-current electronics (1-30 mA) as well as standard AC motor loads up to 440 V.

• Enclosure and Entry: Housed in a rugged enclosure with a Pg 13.5 metal cable gland and screwed cable entry, ensuring a secure and vibration-proof electrical connection.

• Differential Control: Features an adjustable differential type, allowing engineers to fine-tune the "cut-in" and "cut-out" points to prevent rapid cycling of connected equipment.

Technical FAQs

What is the advantage of the "Adsorption Charge" in the 060L315666?

The adsorption charge allows the sensor bulb to be placed in environments either warmer or colder than the switch housing without affecting the accuracy of the setpoint. This makes it superior to vapor charge sensors in applications where the ambient temperature near the controller housing varies significantly.

Can I use this temperature control for low-voltage PLC inputs?

Yes. The 060L315666 features gold-plated contacts designed for reliable switching at low voltages (5-30 V) and low currents (1-30 mA). This prevents oxide buildup on the contacts, which is a common cause of signal failure in standard silver contacts used with PLCs.

How do I adjust the temperature differential?

The differential is adjusted via the internal setting disk. By increasing the differential, you increase the gap between the temperature at which the switch activates and the temperature at which it resets, which is essential for protecting motors and compressors from frequent starting and stopping.

Engineering & Installation Guide

• Capillary Management: When installing the 3000 mm armored capillary, ensure the bend radius never drops below 25 mm. Despite the armoring, sharp bends can cause micro-fractures in the internal tube, leading to a loss of charge and total sensor failure.

• Mounting and Vibration: The KPS series is highly vibration-resistant; however, for maximum longevity in marine engines or compressors, mount the housing on a vibration-damped surface and use the armored capillary to isolate the switch body from the direct heat and vibration of the medium.

• Electrical Sealing: Ensure the Pg 13.5 metal cable gland is tightened correctly to maintain the enclosure's integrity. For installations in high-moisture environments, a "drip loop" in the wiring is recommended to prevent water from traveling down the cable and entering the terminal block.
