The Benefits of Silicon PTC Thermistor Meters
The silicone measuring probe has a TK (temperature coefficient) which is nearly constant over the entire temperature range. Temperature coefficient: α25/50≥0,7%/C.
Excellent long-term stability, annual diversification rate≤0.01C/per year. Temperature drifts over the life of the silicone temperature probe are negligible.
GUILCOR silicone PTC thermistors temperature sensors can withstand more than + 200 ° C without damage.
Finally, silicone PTC thermistor measurement probes have the following advantages:
- small dimensions,
- available for ribbon,
- convenient for automatic installation.

Installation and handling recommendations
Excessive forces applied to a PTC thermistor temperature sensor can cause serious damage. To avoid this, the following recommendations should be observed:
- No perpendicular force should be applied to the glass body;
- During folding, the wires must be held;
- Axial forces on the body can influence the accuracy of the sensor and should be avoided;
- Avoid any force on the body or the leads during or immediately after welding;
- Do not correct the position of an already soldered sensor by pushing, pulling or twisting the body;
- Prevents too rapid cooling after welding;
- For hand soldering, where the fixture is not on a circuit board, the soldering temperature should be <300°C, the soldering time <3s, and the distance between the body and the soldering point > 1,5mm;
- The minimum suitable lead wire length should be ≥ 8 mm;
- In bending the lead wire, the bending point should be more than 2mm away from the glass body part.
