The GRACO 126381 is a Resistance Temperature Detector (RTD) sensor with a 1K Ohm rating and a 4-pin connector. It is designed for accurate temperature measurement and monitoring within GRACO fluid handling and heating equipment. The sensor is typically constructed from durable materials suitable for industrial environments and is intended for use in systems requiring precise temperature control, such as heaters and fluid delivery systems.

Key Features:

• RTD (Resistance Temperature Detector) Sensor
• 126381
• Compatible with GRACO heaters and fluid handling systems (specific models may vary; consult manual)
• High accuracy temperature measurement
• Robust construction for industrial use
• 4-pin connector for reliable electrical connection
• Designed for easy replacement and maintenance
• Reliable performance in demanding environments

Applications:
Used for temperature sensing and control in GRACO fluid heaters and delivery systems, ensuring safe and efficient operation of industrial lubrication and maintenance equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the equipment. Non-genuine parts may result in inaccurate readings or equipment failure.
• Sensor (88) and compression fitting (72) must be replaced together for proper installation
• Position sensor through housing so it protrudes 1/16 to 1/8 inch (1.6 to 3.2 mm) into the fluid outlet
• Tighten compression nut 3/4 turn after sensor is held tight
• Connect M8 plug securely
• Install cover after sensor is in place
• Sensor must always be mounted on the outlet side of the housing; adjust position if outlet is plumbed to the left side
• Regularly inspect sensor and connections for wear or damage
• Replace sensor and fitting together if position is incorrect or after removal
• Ensure proper electrical connections to avoid inaccurate readings
