Large-bore toroidal design helps resist fouling in properly arranged flowing applications.
Overview
ISC40S-GR-T1-03 is a Yokogawa ISC40S inductive conductivity sensor. Its matched toroidal coils are encapsulated so the sensing elements do not directly contact the process.
The GR construction uses glass-filled PEEK, combining erosion resistance with broad chemical resistance. Yokogawa excludes hydrofluoric acid and oxidizing concentrated acids from the normal PEEK application range.
The 03 code identifies the three-metre cable version. The sensor is designed for Yokogawa inductive conductivity analyzers and includes a Pt1000 element for temperature compensation and indication, not process-temperature control.

Features
PEEK sensor body provides abrasion resistance and chemical resistance for compatible process media.
Maximum functional cable length can reach 50 m when the approved WF10 extension cable and BA10 junction box are used.
In-situ calibration is required for stated accuracy when clearance to the holder is less than 25 mm.
Applications
- Conductivity monitoring in chemical cleaning, concentration and interface-detection duties compatible with PEEK.
- Industrial liquid analysis where conventional contacting electrodes would be vulnerable to coating or corrosion.
- Flow-through or immersion installations using a Yokogawa-approved adapter or fitting in compatible material.
About IndustryParts
https://www.industryparts.com/Process chemistry and mounting geometry remain linked
IndustryParts records ISC40S-GR-T1-03 together with analyzer, wetted-material and installation details so the sensor is not reduced to a bare model number.
- PEEK compatibility reviewed
- Cable length retained
- Mounting geometry recorded
Lifecycle
- Confirm process chemistry against PEEK compatibility before selection.
- Keep at least 25 mm clearance where possible, or plan an in-situ calibration.
- Use the Pt1000 signal only for compensation and indication as directed by Yokogawa.
- Inspect the cable, sensor bore, seals and process adapter during scheduled maintenance.
FAQ
Is ISC40S-GR-T1-03 suitable for hydrofluoric acid?
No. Yokogawa reserves PFA-bodied TG versions for hydrofluoric acid and strongly oxidizing concentrated acids; verify the complete wetted-material requirement.
What installation evidence should accompany an ISC40S-GR-T1-03 enquiry?
Send the analyzer model, process chemistry, concentration, temperature, pressure, mounting geometry, cable route and a photo of the complete sensor label.
Can ISC40S-GR-T1-03 be extended beyond its integral cable?
Yes, within Yokogawa guidance: the functional maximum is 50 m when using the approved WF10 extension cable and BA10 junction box.
When is field calibration especially important for ISC40S-GR-T1-03?
Perform in-situ calibration when the sensor has less than 25 mm spacing from the holder or nearby conductive structure, because installation geometry changes the effective factor.
What confirms ISC40S-GR-T1-03 is ready after replacement?
Verify correct analyzer configuration, cable integrity, temperature indication, air/zero behavior, calibration response and stable conductivity in the actual process arrangement.
