The embedded Pt1000 RTD continuously measures process fluid temperature, enabling automatic temperature compensation (ATC) calculations within the analyzer. The solid platinum ground pin stabilizes potential measurements and enables simultaneous pH and ORP monitoring over 4-20 mA HART loop communication links while isolating measurement paths from ground loop noise.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the solid platinum earthing pin enhance measurement accuracy in grounded process lines?\u003c\/p\u003e\n\u003cp\u003eA: The platinum earth pin provides a direct reference connection to the liquid medium, eliminating solution ground potential offsets and allowing the connected analyzer to execute diagnostic impedance checks on the glass electrode.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integral 10-meter cable be spliced or extended in the field?\u003c\/p\u003e\n\u003cp\u003eA: Field splicing is not recommended due to high-impedance pH signal vulnerability; any required extension must utilize a high-insulation junction box and shielded coaxial extension cabling.\u003c\/p\u003e\n\u003cp\u003eQ: What process connection threads are present on the sensor body?\u003c\/p\u003e\n\u003cp\u003eA: The sensor body features 3\/4-inch male NPT threads on both ends, allowing direct immersion mounting or insertion into standard flow fittings and pipe tees.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eField engineers must execute sensor installation in accordance with standard industrial piping and wiring practices:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eRemove the protective hydration cap from the sensing head and inspect the glass bulb and reference junction for cracks or salt buildup.\u003c\/li\u003e\n\u003cli\u003eApply PTFE tape to the 3\/4-inch NPT pipe threads and thread the sensor hand-tight into the mounting fitting before applying a 1\/4 turn with a wrench.\u003c\/li\u003e\n\u003cli\u003eInstall the sensor at an angle at least 15 deg above the horizontal plane to prevent air bubbles from trapping inside the glass electrode bulb.\u003c\/li\u003e\n\u003cli\u003eRoute the 10-meter integral cable through grounded conduit, keeping it physically separated from AC power lines and variable frequency drive cabling.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43901445636186,"sku":"FU20-10-T1-NPT","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/68_38ed5021-0651-42b8-b73b-bd57567b1c58.jpg?v=1787621742","url":"https:\/\/www.spareoil.com\/products\/fu20-10-t1-npt-yokogawa-ph-orp-combination-sensor","provider":"SpareOil Automation","version":"1.0","type":"link"}
