A/1K-3W-SP | ACI | Temperature Sensors & Transmitters

The ACI Platinum Wall Plate Series features a decorative Stainless Steel or Aluminum wall plate with two or three Teflon colored lead wires to differentiate between the different sensor types. All three-wire 3W sensors should be ordered when using with a 3-Wire temperature transmitter or sensor configuration on your building management system or PLC (Programmable Logic Controller). The purpose of the 3rd wire is to compensate for external lead wire resistance that will affect the accuracy of your sensor. ACI recommends the use of 18 AWG lead wires to reduce the effect of external lead wire resistance when using a Platinum RTD. The sensors in this series are manufactured using ACI’s double encapsulation process to eliminate the effects of moisture upon the sensors and to increase the thermal response using our high quality, thermally conductive epoxy. A foam pad is included to insulate the sensor from thermal drafts within the wall. All wall plates are will provide a level of security and protection to the sensor when mounted over a single gang junction box or hole in the wall with the use of drywall anchors. Tamper Proof mounting screws, screw driver bits and NIST Certificates are available as referenced on the back of the data sheet.
