1. Introduction
This manual provides essential information for the proper use, setup, and maintenance of your PerfectPrime TL2300 K-Type Thermocouple Sensor Extension Cable. Please read these instructions carefully before use to ensure optimal performance and longevity of the product.
2. Product Overview
The PerfectPrime TL2300 is a K-Type thermocouple extension cable designed to extend the reach of your K-Type thermocouple sensors to compatible measuring devices. It features standard K-Type flat connectors for reliable and accurate temperature signal transmission.
2.1 Key Features
- Connector Type: Female to Male K-Type Flat connector
- Maximum Temperature Rating: 300 °C (for the cable insulation)
- Length: 3 meters / 9.8 feet
- Wire Material: Polytetrafluoroethylene (PTFE) insulated wire
- Weight: Approximately 35g
2.2 Components
The TL2300 cable consists of a K-Type thermocouple wire terminated with a male flat pin connector on one end and a female flat socket connector on the other.

3. Setup
Follow these steps to properly connect your TL2300 extension cable with a K-Type thermocouple sensor and a compatible measuring device.
- Identify Connectors: The TL2300 cable has a male flat pin connector and a female flat socket connector. K-Type connectors are typically yellow.
- Connect Sensor: Plug the male flat pin connector of your K-Type thermocouple sensor into the female flat socket connector of the TL2300 extension cable. Ensure a firm connection.
- Connect to Device: Plug the male flat pin connector of the TL2300 extension cable into the K-Type input port of your compatible temperature measuring device (e.g., thermometer, datalogger). Observe polarity: the wider pin/socket typically corresponds to the positive (+) terminal, and the narrower pin/socket to the negative (-) terminal. K-Type connectors are designed to prevent incorrect polarity connection, but always verify.

4. Operating Instructions
Once the TL2300 extension cable is correctly connected between your K-Type thermocouple sensor and measuring device, operation is straightforward.
- Power On: Turn on your temperature measuring device.
- Verify Connection: Ensure the device recognizes the connected thermocouple and displays a temperature reading. If the reading is erratic or shows an error, check all connections.
- Take Measurements: Position your K-Type thermocouple sensor at the desired measurement point. The extension cable allows for greater flexibility in sensor placement.
- Observe Readings: Monitor the temperature readings on your device. The TL2300 cable is designed to transmit the thermocouple signal accurately over its length.
Important Considerations:
- Avoid bending the cable sharply, as this can damage the internal wiring.
- Do not exceed the maximum temperature rating of the cable insulation (300 °C).
- Ensure the environment where the cable is used is free from excessive moisture or corrosive substances unless the cable is specifically rated for such conditions.
5. Maintenance
Proper care and maintenance will help prolong the life and accuracy of your TL2300 extension cable.
- Cleaning: Wipe the cable and connectors with a clean, dry cloth. If necessary, use a slightly damp cloth with mild soap, then dry thoroughly. Do not immerse the connectors in liquid.
- Storage: Store the cable in a clean, dry environment, away from direct sunlight and extreme temperatures. Avoid coiling the cable too tightly.
- Inspection: Periodically inspect the cable and connectors for any signs of wear, damage, or corrosion. Replace the cable if any damage is observed to prevent inaccurate readings or electrical hazards.
- Handling: Always handle the connectors by their plastic housing, not by pulling on the cable itself.
6. Troubleshooting
If you encounter issues with your TL2300 extension cable, consider the following troubleshooting steps:
- No Reading or Erratic Readings:
- Ensure all connections (sensor to cable, cable to device) are secure and fully inserted.
- Verify that the thermocouple sensor itself is functioning correctly by testing it directly with the measuring device if possible.
- Check for any visible damage to the cable or connectors.
- Incorrect Temperature Reading:
- Confirm that both the sensor and the measuring device are set to the correct thermocouple type (K-Type).
- Ensure there are no strong electromagnetic fields near the cable, which can interfere with the signal.
- Verify that the cable is not exposed to temperatures exceeding its maximum rating, which could affect its insulation and signal integrity.
If problems persist after following these steps, contact PerfectPrime customer support for further assistance.
