The potentiometric output requires high-impedance amplification, facilitated by the integrated Pt1000 temperature element which provides real-time slope compensation. This integration suppresses measurement drift and maintains Nernstian response stability in variable-temperature streams.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the internal Pt1000 sensor compatible with non-Yokogawa transmitters?\u003c\/p\u003e\n\u003cp\u003eA: The Pt1000 element follows standard resistance-temperature characteristics (IEC 60751). It is electrically compatible with any process transmitter capable of accepting a 2-wire Pt1000 input; ensure the transmitter is correctly configured for the specific resistance range and cable impedance.\u003c\/p\u003e\n\u003cp\u003eQ: Can the NPT threads be used for submersion applications?\u003c\/p\u003e\n\u003cp\u003eA: While the NPT threads provide a secure mechanical mount for pipe installation, submersion requires additional protection for the cable entry point. Ensure the sensor is installed with a dedicated submersion assembly to prevent moisture ingress at the cable-to-sensor junction.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePerform a multi-point buffer calibration before installation to verify electrode slope and offset consistency.\u003c\/li\u003e\n\u003cli\u003eInstall the sensor in a vertical or inclined position (at least 15 degrees above the horizontal) to ensure the internal reference electrode remains in contact with the electrolyte gel.\u003c\/li\u003e\n\u003cli\u003eApply Teflon-based thread sealant to the 3\/4 inch NPT threads, ensuring the sensor is hand-tightened followed by a quarter-turn with a wrench; do not over-torque to avoid damaging the sensor body.\u003c\/li\u003e\n\u003cli\u003eRoute the 5-meter cable through flexible, liquid-tight conduit to protect it from mechanical abrasion and process chemical exposure.\u003c\/li\u003e\n\u003cli\u003eIn high-flow environments, verify that the sensor is not placed in a location subject to excessive turbulence, which could induce measurement noise and physical vibration fatigue.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49219735355644,"sku":"FU20-05-T1-NPT","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/FU20-05-T1-NPT2.jpg?v=1782177845","url":"https:\/\/www.electronicplc.com\/ar\/products\/yokogawa-fu20-05-t1-npt-wide-body-sensor","provider":"Electronic PLC","version":"1.0","type":"link"}
