ACCURATE TEMPERATURE SENSING
Thermocouple Pt100 M4
Thermocouple Pt100 M4 by LICHENGDA. RTD wiring and insertion geometry, configuration details and made-to-drawing quotation for repeatable process-temperature measurement.
PRODUCT ENGINEERING
RTD wiring and insertion geometry
Thermocouple Pt100 M4: Match the named platinum resistance sensor to the controller’s configured input. Confirm the resistance designation, accuracy class and 2-, 3- or 4-wire arrangement before connecting the probe.
Insertion depth, probe diameter and mounting contact affect response and measurement error. Route the signal cable away from heater power wiring and review cable resistance for the selected connection scheme.
For Thermocouple Pt100 M4, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Repeatable process-temperature measurement. The final suitability of Thermocouple Pt100 M4 depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

Description
Product Description
OEM ODM industrial M8 rtd E J K type high temperature sensor thermocouple m6 screw
An M3/M4 screw thermocouple is a compact temperature sensor with either an M3 (3mm) or M4 (4mm) threaded screw for easy mounting in tight spaces or small equipment. These are commonly used in electronics, industrial automation, and precision instruments where secure attachment and fast thermal response are needed.
Key Features & Differences
| Feature | M3 Screw Thermocouple | M4 Screw Thermocouple |
|---|---|---|
| Thread Size | 3mm diameter | 4mm diameter |
| Strength | Less robust, for low-vibration applications | More durable, better for industrial use |
| Response Time | Faster (smaller mass) | Slightly slower (larger mass) |
| Common Uses | PCBs, small electronics, drones, lab tools | Motors, extruders, CNC machines, HVAC |
| Max Temp | Depends on thermocouple type (e.g., Type K: up to 1250°C) |
