RTD wiring and insertion geometry
K E T PT100 RTD Thermocouple: 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.
The archived configuration for K E T PT100 RTD Thermocouple lists Cable material: Shielded wire,Fiberglass, PTFE, silicon; Thread size: M5/M6/M8; Thread size: M6*1/ M6*1.25. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For K E T PT100 RTD Thermocouple, 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

ARCHIVED PRODUCT INFORMATION
Description
Product Description
thermocouple is a temperature measurement device consisting of two dissimilar metal wires joined at one end, called the measurement or "hot" junction. The other end, where the wires are not joined, is connected to the instrumentation, typically referred to as the "cold" junction or reference junction. The thermocouple generates a voltage proportional to the temperature difference between the hot and cold junctions, known as the Seebeck effect.

Key Features of Thermocouples:
Wide Temperature Range: Thermocouples can measure a broad range of temperatures, from cryogenic levels to over 2000°C, depending on the type.
Durability: They are robust and can withstand harsh environments, including high pressure, vibration, and corrosive conditions.
Fast Response: Due to their small size and low thermal mass, thermocouples respond quickly to temperature changes.
Cost-Effective: They are relatively inexpensive compared to other temperature sensors.
Product Advantage
1:High Precision Temperature control probe
2:Accurate measurement (imported chip),high sensitivity
3:fast response,anti-interference,Good temperature resistance
4:Protection spring,Stainless steel special plug
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) |
Typical Applications
M3:
3D printer hotends & heated beds
Small motors & servos
Battery packs (EVs, drones)
Medical devices
M4:

Types of Thermocouples:
Thermocouples are classified into different types based on the metal combinations used. Each type has a specific temperature range and application suitability:
Type K (Chromel-Alumel): Most common, suitable for a wide range of temperatures (-200°C to 1260°C).
Type J (Iron-Constantan): Used in reducing environments, range from -210°C to 1200°C.
Type T (Copper-Constantan): Ideal for cryogenic applications, range from -250°C to 400°C.
Type E (Chromel-Constantan): High output, suitable for cryogenic and moderate temperatures (-200°C to 900°C).
Type N (Nicrosil-Nisil): Stable at high temperatures, range from -270°C to 1300°C.
Type R/S (Platinum-Rhodium): Used for very high temperatures (up to 1600°C), often in laboratory settings.
Type B (Platinum-Rhodium): Suitable for extremely high temperatures (up to 1800°C).
