ACI Balco RTD Copper Averaging

Features

  • Bendable copper sensing element with two colored lead wires.
  • Manufactured with multiple sensing points determined by the length of the sensing element.
  • Provide a more accurate average temperature of the air inside large ducts when compared to that of a single-point sensor.
  • Each of the elements is hermetically sealed to prevent moisture intrusion and includes an integrated foam pad to seal the duct and dampen vibrations.
  • Copper has also been proven to provide an additional antibacterial effect to many of the airborne contaminants, molds, and bacteria found in duct systems.
  • Sensor lengths are selected based on the dimensional area of your duct.
  • ACI’s standard enclosures include the “-GD” Galvanized or “-PB” plastic box with a hinged cover.
  • Each unit includes nylon wire ties and mounts for mounting.
  • Optional copper capillary and universal mounting clips, NEMA/IP-rated weatherproof enclosures.
  • NIST Certificates are also available.

Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

The ACI Balco Copper Averaging Series features a bendable copper sensing element with two colored lead wires to differentiate the different sensor types. The sensors in this series are manufactured with multiple sensing points determined by the length of the sensing element. Averaging sensors provide a more accurate average temperature of the air inside large ducts when compared to that of a single-point sensor. Each of the elements is hermetically sealed to prevent moisture intrusion and includes an integrated foam pad to seal the duct and dampen vibrations. The benefits of copper sensing elements are that they have improved thermal conductivity and higher corrosion resistance when compared to similar aluminum-style sensors. Copper has also been proven to provide an additional antibacterial effect to many of the airborne contaminants, molds, and bacteria found in duct systems. Sensor lengths should be selected based on the dimensional area of your duct. ACI’s standard enclosures include the “-GD” Galvanized or “-PB” plastic box with a hinged cover. Each unit includes nylon wire ties and mounts for mounting. Optional copper capillary and universal mounting clips, NEMA/IP-rated weatherproof enclosures, and NIST Certificates are also available.
