ACI Balco RTD Immersion

Features

  • ¼” diameter stainless steel probe with two, 14-inch 22 AWG Etched Teflon colored lead wires.
  • The immersion sensors come standard with a welded thermowell “-I” version but can also be ordered without the thermowell “-INW” version.
  • The “-INW” Version includes a standard ½” NPS (National Pipe Straight) process thread to be used with an optional machined thermowell or in an existing thermowell application.
  • This series can be ordered with optional NEMA-rated weatherproof enclosures.
  • NIST Certificates as referenced on the back of the product datasheet.

Category:

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 Immersion Series features a ¼” diameter stainless steel probe with two, 14-inch 22 AWG Etched Teflon colored lead wires to differentiate the many different sensor types. The sensors in this series are manufactured using ACI’s proven double encapsulation process to eliminate the effects of moisture upon the sensors and to increase the thermal response times using our high-quality, thermally conductive epoxy. The immersion sensors come standard with a welded thermowell “-I” version but can also be ordered without the thermowell “-INW” version. The “-INW” Version includes a standard ½” NPS (National Pipe Straight) process thread to be used with an optional machined thermowell or in an existing thermowell application. This series can be ordered with optional NEMA-rated weatherproof enclosures and NIST Certificates as referenced on the back of the product datasheet.

Applications

  • Chilled Water Systems
  • Hot Water Systems
  • Boilers, Pumps
  • Compressor
  • Chillers

The ACI Balco RTD Immersion Series is covered by ACI’s Five (5) Year Limited Warranty.
