Shop HITACHI EX100-2-3 THERMOMETER SWITCH (OVER HEAT WARNING) | Tonkee®

Temperature Sensing: The primary function of the thermometer switch is to monitor the temperature of specific components or areas within the excavator.

These components typically include the engine, hydraulic system, and transmission. This is achieved through the use of temperature sensors placed in strategic locations.

Temperature Thresholds: The thermometer switch is programmed with predefined temperature thresholds. These thresholds represent the upper limits of safe operating temperatures for the monitored components. When the temperature in any of these components exceeds the threshold, the switch is triggered.

Warning Signal: Upon triggering, the thermometer switch initiates a warning signal. This signal can take various forms, including visual indicators on the equipment's control panel, audible alarms, or even automatic shutdown of the excavator's engine. The exact response depends on the equipment's design and the severity of the temperature increase.

Protection Mechanism: In some cases, when the thermometer switch detects an extreme temperature rise that poses a severe risk to the equipment, it can initiate an automatic shutdown to prevent further damage. This feature helps safeguard the equipment from catastrophic failures due to overheating.

Reset Mechanism: After the temperature in the monitored components returns to safe levels, the thermometer switch typically includes a reset mechanism.

This allows the equipment to resume normal operation once the issue causing the temperature increase has been resolved.

Diagnostic Capabilities: Modern thermometer switches may also include diagnostic features. These capabilities enable equipment operators and maintenance personnel to identify the specific component or area that triggered the warning, facilitating rapid troubleshooting and repair.

Integration: The thermometer switch is a critical component integrated into the excavator's broader control and monitoring system. It works in conjunction with other sensors and safety mechanisms to ensure the overall operational safety of the equipment.
