5. Configuració i instal·lació

The sensor probes are designed for easy integration with compatible temperature controllers such as W1209, STC-1000, and W3001. The specific wiring will depend on the sensor type (NTC 10K or DS18B20) and the controller's input requirements.

5.1. NTC 10K Thermistor Probe Wiring

NTC 10K thermistors typically have two wires and are connected to analog input pins on a controller. The controller measures the resistance change of the thermistor, which corresponds to temperature. Ensure your controller supports NTC 10K sensors.

Passos de connexió:

1. Identify the temperature sensor input terminals on your controller (e.g., STC-1000).
2. Connect the two wires from the NTC 10K probe to these terminals. Polarity usually does not matter for NTC thermistors, but consult your controller's manual for specific instructions.
3. Secure the connections to prevent accidental disconnection.

5.2. DS18B20 Digital Temperature Probe Wiring

DS18B20 sensors are digital and use a 1-Wire protocol, typically requiring three connections: VCC (power), GND (ground), and DQ (data). Some versions may have only two wires if parasitic power mode is used, but most common implementations use three. Ensure your controller supports DS18B20 digital sensors and the 1-Wire protocol.

Typical 3-Wire Connection (consult your controller's manual for exact pinout):

• Fil vermell: VCC (Power, e.g., +5V)
• Fil negre: GND (terra)
• Fil groc: DQ (Data Line, often requires a pull-up resistor to VCC, typically 4.7kΩ)

Passos de connexió:

1. Identify the VCC, GND, and Data input terminals on your controller.
2. Connect the corresponding wires from the DS18B20 probe to these terminals.
3. If required by your controller or circuit design, install a pull-up resistor between the Data line and VCC.

5.3. Col·locació de la sonda

Place the stainless steel probe tip in the environment where temperature measurement is required. Ensure the probe is fully immersed if measuring liquid temperatures, or adequately exposed to air if measuring ambient temperatures. The waterproof design allows for direct contact with water or other non-corrosive liquids.

6. Instruccions de funcionament

Once the sensor probe is correctly installed and connected to a compatible temperature controller, its operation is straightforward:

1. Encès: Apply power to your temperature controller.
2. Visualització de la temperatura: The controller should automatically detect the sensor and display the current temperature reading.
3. Configuració del controlador: Refer to your specific temperature controller's manual (e.g., W1209, STC-1000, W3001) for instructions on setting temperature thresholds, calibration, and other operational parameters. The sensor probe acts as the input device, providing accurate temperature data to the controller.

7. Manteniment

These temperature sensor probes are designed for low maintenance. Follow these guidelines to ensure longevity:

• Neteja: If the stainless steel probe tip becomes dirty, gently wipe it with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the probe or cable.
• Inspecció: Periodically inspect the cable for any signs of damage, such as cuts, kinks, or exposed wires. Ensure the probe tip is free from excessive buildup that might affect readings.
• Emmagatzematge: When not in use, store the sensor in a clean, dry place within its specified temperature range.

8. Solució De Problemes

If you encounter issues with your temperature sensor probe, consider the following common problems and solutions:

• No Temperature Reading / Error Display:
  • Check all wiring connections to ensure they are secure and correctly matched (VCC, GND, Data for DS18B20; two terminals for NTC).
  • Verify that the power supply to the controller is stable and within the sensor's operating voltage gamma.
  • Ensure the correct sensor type (NTC 10K or DS18B20) is selected or compatible with your temperature controller.
  • For DS18B20, confirm the presence and correct value of the pull-up resistor on the data line if required by your setup.
  • Inspeccioneu el cable per veure si hi ha danys visibles.
• Lectures de temperatura inexactes:
  • Ensure the probe tip is properly positioned in the area where temperature needs to be measured and is not affected by external heat sources or drafts.
  • Check for any buildup or debris on the probe tip that might insulate it from the environment.
  • If your controller has a calibration function, perform a calibration according to its manual.
  • Verify that the sensor type configured in your controller matches the connected probe (e.g., NTC 10K vs. DS18B20).

9. Consells d'usuari

• Compatibilitat del controlador: When selecting a sensor, always confirm its compatibility with your temperature controller. For example, the STC-1000 controller typically uses NTC 10K thermistors. If you are using a DS18B20 sensor, ensure your controller explicitly supports the 1-Wire digital protocol.
• Longitud del cable: While these probes are available in lengths up to 3 meters, for applications requiring significantly longer distances (e.g., 30 meters), consider potential signal degradation. For DS18B20 sensors, longer cable runs might require careful wiring, shielded cables, or signal amplifiers to maintain data integrity.
• Segellat ambiental: Even though the probe is waterproof, ensure that the connection points to your controller are adequately protected from moisture, especially in high-humidity or outdoor installations, to prevent short circuits or corrosion.

10. Preguntes freqüents (FAQ)

Q: Which sensor type is suitable for an STC-1000 temperature controller?

A: The STC-1000 controller is commonly designed to work with NTC 10K thermistor probes. Please verify your specific STC-1000 model's manual for confirmation.

Q: Can I use a sensor with a 30-meter cable length?

A: Our standard probes are available up to 3 meters. While it might be technically possible to extend cables, signal integrity can be an issue, especially for digital sensors like DS18B20. For custom lengths or very long runs, specialized wiring and signal conditioning may be required. It is recommended to use the provided lengths or consult an expert for extensions.

Q: Is the entire cable waterproof?

A: The stainless steel probe tip is waterproof and moisture-proof. The PVC wire itself is resistant to moisture, but the connection points (exposed wires or connectors) should be properly sealed and protected if they are to be exposed to wet conditions.
