A KTY temperature sensor is specified by its exact part family and resistance-temperature characteristics, not by the KTY label alone. Some silicon KTY series have a positive temperature coefficient, but curves, tolerances, package, operating limits, and availability vary by model. Confirm the supplier datasheet and full model designation before matching it to a readout circuit or replacement probe.
Confirm model and curve data
Record the manufacturer and exact part number, reference resistance and temperature, curve or resistance table, tolerance, operating span, and any model-specific qualification. Do not substitute one KTY variant for another using the family name alone. For an OEM assembly, confirm whether the requirement is a bare element or a finished sensor/probe.
Match the readout and operating current
Check the controller input, excitation or measurement current, conversion method, filtering, and open/short fault detection. Sensor current can affect self-heating, so validate the circuit under the actual installation and measurement interval. Use the documented resistance-temperature curve for conversion rather than assuming a generic linear relationship.
Specify a finished KTY probe
If the element is built into a probe, define the sensing point, dimensions, encapsulation or sheath, cable, connector, mounting, response requirement, and environmental exposure. Mechanical protection, thermal contact, and cable routing affect how a finished assembly performs. Confirm insulation, moisture and chemical resistance, vibration, and service conditions for the selected construction.
Validate compatibility and replacements
For replacement projects, compare the full curve, tolerance, package or probe construction, controller conversion, and wiring—not just nominal resistance. Check the new assembly with the intended readout at representative operating points and document any required recalibration or firmware conversion changes.
KTY sensor RFQ checklist
- Exact manufacturer, family, model number, curve, and reference point.
- Resistance tolerance, operating span, excitation, conversion method, and input model.
- Bare element or finished probe; dimensions, mounting, cable, connector, and materials.
- Response, moisture, chemicals, vibration, insulation, and service-life requirements.
- Calibration, sample quantity, production volume, inspection, and drawing revision.
Review temperature sensor options
Browse the temperature sensor range and include the exact KTY model, datasheet, controller input, and installation drawing when you contact Starlight for an OEM review. Confirm model-specific compatibility and supply details before design-in.
