The purpose of the 3rd wire is to compensate for external lead wire resistance that will affect the accuracy of your sensor output when using with a three wire temperature transmitter or sensor configuration on your Building Management System or PLC (Programmable Logic Controller. ACI recommends the use of 18 AWG lead wires to reduce the external lead wire resistance when using the A\/100\/1K-3W-O style Platinum RTD series sensors without temperature transmitter. The operating specifications are for both the sensor and transmitter as designated in the specification table. The transmitter is mounted in the Galvanized junction and should be mounted inside your building with the sensor assembly mounted in the Aluminum Bell Box for mounting outdoors due to the extreme temperatures. NIST Certificates are available for all of the configurations listed in the ordering grid on the back of the product data sheet. For best accuracy, ACI recommends the use of the TTM100 or TTM1K Series Matched transmitters with a 3 or 5 Point NIST Calibration Certificate since they include a second calibration step in which the RTD and transmitter are calibrated together as a system, which will remove most of the sensor error over the calibrated temperature span of the transmitter.","brand":"ACI","offers":[{"title":"Default Title","offer_id":47991392665840,"sku":"ACI-A1003WLTOBB","price":192.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/5118\/9744\/files\/aci-a100-3w-lt-o-bb.jpg?v=1758690727"},{"product_id":"aci-a1003wo4x","title":"A\/100-3W-O-4X","description":"The ACI Platinum Outside Air Series features a weather proof European style, plastic enclosure with twist o cover and water tight cord grip.
