Combines pH measuring, reference and temperature functions in one wide-body assembly.
Product Overview
FU20-10-T1-NPT is a Yokogawa FU20 wide-body combination pH/ORP sensor. Its model code fixes the cable, temperature element and body style.
The 10 suffix denotes a 10 m integral cable; T1 denotes Pt1000; NPT denotes the PPS body with tapered thread and dome-shaped sensing end.
The dimensional drawing shows a 3/4-inch tapered process thread that fits a 3/4 NPT female connection.
Performance
Provides the Pt1000 signal used by the analyzer for compensation.
Uses the integral 10 m cable to avoid an intermediate connector at the sensor body.
Mounts through the specified tapered-thread process connection or an approved adapter.

System Integration
- Confirm analyzer support for the FU20 electrode system and Pt1000 input.
- Verify chemical compatibility of the PPS body and all wetted sealing materials.
- Plan cable routing without cutting, extending or coiling against manufacturer guidance.
- Confirm the process fitting accepts the 3/4 NPT tapered-thread arrangement.
Applications
- Industrial pH or ORP measurement with compatible chemistry and mounting.
- Tank, pipe or flow assembly duties that suit a wide-body combination sensor.
- Replacement of the exact 10 m, Pt1000, NPT configuration.

FAQ
Q01What details should accompany an FU20-10-T1-NPT enquiry?
Send the full sensor code, analyzer model, process chemistry, range, temperature, pressure, fitting, cable route and required cleaning or adapter options.
Q02Can FU20-10-T1-NPT replace FU20-10-T2-NPT?
Not without analyzer review. T1 is Pt1000 and T2 is Pt100, so the temperature input and compensation configuration differ.
Q03How should a stored FU20-10-T1-NPT be evaluated?
Inspect the glass, reference junction, cable and thread, confirm wet-storage condition where applicable, then calibrate with fresh traceable buffers before service.
Q04What installation mistakes most often affect FU20-10-T1-NPT?
Incorrect thread engagement, trapped air, poor cable routing, unsuitable chemistry and an analyzer configured for the wrong temperature element can all compromise performance.
Q05What proves FU20-10-T1-NPT is ready after replacement?
Record exact model identity, leak-free mounting, stable Pt1000 reading, successful two-point pH calibration or approved ORP check and stable process response.
