The \u003cstrong\u003e104502\u003c\/strong\u003e Bell \u0026amp; Gossett Ecocirc XL Temperature Sensor (model KYT83\/121) provides reliable feedback to the boiler controller, ensuring consistent comfort and energy savings.\u003c\/p\u003e\u003cp\u003eThe sensor utilizes a stainless‑steel probe and a sealed thermistor element that translates fluid temperature into an electrical signal. As water circulates past the probe, the thermistor’s resistance changes proportionally, allowing the controller to modulate burner output and pump speed in real time.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Response Time:\u003c\/strong\u003e Detects temperature shifts within seconds for quick boiler adjustments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Operating Range:\u003c\/strong\u003e Accurate from 0 °C to 100 °C, covering typical hydronic applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Construction:\u003c\/strong\u003e Stainless‑steel housing resists corrosion in potable and closed‑loop systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for residential and light‑commercial Ecocirc XL boiler installations, domestic hot water recirculation loops, and low‑temperature heating circuits.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43118528462942,"sku":"104502","price":138.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/104502_image_541ca06a-67cd-4c06-a462-16daf0a3c500.png?v=1785975388","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-104502-ecocirc-xl-temperature-sensor","provider":"National Boiler Supply","version":"1.0","type":"link"}
