Product Overview

The KPS79 060L313766 (060L313766) is a rugged, high-performance thermostat designed to meet the rigorous demands of the marine and heavy industry sectors. Engineered for high-vibration environments, this KPS series switch is the go-to solution for monitoring critical temperatures in diesel engines, cooling systems, and industrial plant machinery. The KPS79 060L313766 features a robust contact system that ensures consistent switching accuracy even under extreme mechanical stress. With its specialized sensor design for direct mounting into thermowells, it provides a localized, high-integrity monitoring point for processes where temperature stability is vital to preventing equipment damage and maintaining operational safety.

Technical Configuration

The KPS79 060L313766 is configured with a temperature setting range of 50 to 100 deg C, making it ideal for standard engine jacket water and lubrication oil monitoring. It features an adjustable mechanical differential (hysteresis) of 4 to 16 deg C, allowing engineers to prevent rapid cycling of connected pumps or alarms by defining precise cut-in and cut-out points. This specific model is a direct-mount version (no capillary tube), designed to be paired with a 160 mm sensor pocket for immersive medium sensing. The hardware is built to survive a maximum sensor temperature of 200 deg C, providing a significant safety buffer for process overshoots. Housed in a heavy-duty enclosure, the switch is highly resistant to seawater, humidity, and the intense vibrations common in shipboard engine rooms.

Technical FAQs

What is the advantage of the KPS 79 over standard thermostats?

The KPS series is specifically built for "heavy duty" environments. Its contact system is designed to withstand vibrations and shocks that would cause standard thermostats to fail or trigger false alarms. The IP67 rating ensures it remains functional in wet, saline, or dusty conditions.

Can this switch be used without a sensor pocket?

While the KPS79 is a direct-mount unit, it is highly recommended to use the 160 mm sensor pocket (thermowell). This allows for the sensor to be removed or replaced without draining the tank or piping system, and it protects the sensor bulb from high-pressure surges and corrosive media.

How do I adjust the temperature differential?

The differential is adjusted via an internal screw within the switch housing. By increasing the differential (up to 16 deg C), you can prevent "chattering" or frequent switching in systems where the temperature fluctuates rapidly around the setpoint.

Is this model suitable for marine certifications?

Yes, the KPS series is designed with marine approvals in mind (such as DNV, GL, LR, and BV). It is widely used in engine rooms and deck machinery where Type Approval is a mandatory requirement.

Engineering & Installation Guide

• Sensor Pocket Integration: For optimal response time, the 160 mm sensor pocket should be installed in an area with high flow turbulence, such as a pipe bend or the center of a tank. Use a thermal conductive medium (heat paste) inside the pocket to ensure rapid heat transfer from the medium to the sensor bulb.

• Vibration Mitigation: Although the KPS79 is vibration-resistant, ensure the mounting surface is rigid. When mounting on a engine block or high-vibration compressor, check that the electrical conduit is flexible to prevent the transmission of mechanical stress through the wiring into the switch terminals.

• Sealing and Maintenance: To maintain the IP67 protection rating, ensure the cover screws are tightened evenly and the cable gland is properly sized for the cable diameter. Periodically inspect the internal contacts for signs of arcing if switching high-inductive loads; using an external relay or contactor is recommended for high-current applications to prolong switch life.
