1. Киришүү
The ACI A/100KS-D-4"-PB Duct Temperature Sensor is a precision instrument designed for accurate temperature measurement within HVAC, building automation, and light industrial systems. This sensor utilizes a 100k ohm thermistor at 77°F (25°C) to provide reliable temperature data. Its robust design includes a plastic duct mount configuration with a mounting flange for easy installation and a foam pad to minimize vibration. The sensing element is double encapsulated to prevent moisture infiltration, ensuring long-term performance and reliability.
Typical applications for this sensor include zone control, air handling units, and general temperature monitoring within ductwork environments.

Figure 3.1: ACI A/100KS-D-4"-PB Duct Temperature Sensor. This image shows the ACI A/100KS-D-4"-PB Duct Temperature Sensor. It features a black plastic enclosure with a metal temperature probe extending upwards. The enclosure has a mounting flange and visible knockouts for wiring.
4. Орнотуу жана орнотуу
The ACI duct temperature sensor is designed for straightforward installation in ductwork.
4.1. Сайтты тандоо
- Choose a location in the ductwork that provides a representative temperature reading of the air stream. Avoid areas directly downstream of coils, fans, or other heat sources/sinks that could skew readings.
- Ensure sufficient clearance for mounting the plastic enclosure and inserting the probe into the duct.
4.2. Монтаждоо
- Drill a hole in the ductwork large enough to accommodate the 4-inch sensor probe.
- Position the sensor's mounting flange against the duct surface. The integrated foam pad on the enclosure helps dampen vibrations and provides a seal.
- Secure the enclosure to the duct using appropriate screws through the mounting holes on the flange.
4.3. Электр зымдары
- Open the plastic enclosure.
- Route the necessary wiring through one of the knockouts provided on the enclosure.
- Connect the sensor wires to your building automation system or controller according to the system's wiring diagram. Refer to the specifications section for thermistor resistance values.
- Бардык байланыштар коопсуз жана изоляцияланганын текшериңиз.
- Close the enclosure securely after wiring is complete.
5. Иштөө принциптери
The A/100KS-D-4"-PB sensor operates on the principle of thermistor resistance change with temperature. A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. As the ambient air temperature within the duct changes, the resistance of the 100k ohm thermistor element changes accordingly. Your building automation system or controller measures this resistance change and converts it into a temperature reading.
The double-encapsulated sensing element ensures that the thermistor remains protected from moisture, which is crucial for maintaining accuracy and longevity in duct environments.
6. Техникалык тейлөө
The ACI Duct Temperature Sensor is designed for minimal maintenance. However, periodic checks can ensure optimal performance.
- Жылдык текшерүү: Annually inspect the sensor and its wiring for any signs of physical damage, corrosion, or loose connections.
- Тазалоо: If dust or debris accumulates on the probe or enclosure, gently wipe it clean with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Кайра калибрлөө: While these sensors are generally stable, if significant discrepancies in temperature readings are observed, consult your building automation system's documentation for recalibration procedures or consider professional service.
