The Graco SENSOR, CAPACITIVE, 18MM, QCK DISC is a specialized component used in various fluid handling systems for detecting the presence of materials. Here’s an overview of its features:

• Capacitive Sensor: This type of sensor detects changes in capacitance, allowing it to sense the presence or absence of materials without direct contact. It’s particularly effective for liquids, powders, and granular materials.
• 18MM Size: The 18mm designation refers to the diameter of the sensor, making it compact enough for integration into tight spaces within machinery.
• Quick Disconnect (QCK): The "QCK DISC" indicates a quick disconnect feature, allowing for easy installation and removal without the need for tools, facilitating maintenance and adjustments.
• Applications: Commonly used in spray equipment, pumps, and other fluid handling systems to monitor fluid levels, detect leaks, or control processes based on material presence.
• Durability: Typically constructed from robust materials designed to withstand environmental factors such as moisture, dust, and chemicals, ensuring long-lasting performance.

Overall, this capacitive sensor enhances the efficiency and reliability of Graco systems by providing accurate and responsive monitoring of material presence.
