A/100-3W-O-4X | RTD 100 ohm (3 wire) | Outdoor Outside Air Temperature Sensor | NEMA 4X Housing Enclosure Box The ACI Platinum Outside Air Series features a weather proof European style, plastic enclosure with twist off cover and water tight cord grip. The sensing element contains Etched Teflon colored lead wires to differentiate the sensor types. The three-wire -3W option should be ordered if 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 your sensors output signal. ACI recommends the use of 18 AWG lead wires to reduce external lead wire resistance when using a Platinum RTD sensor. The sensors in this series are manufactured using ACIs proven double encapsulation process to eliminate the effects of moisture on the sensor and to increase response time using our high quality, thermally conductiv
