Choosing a suitable Supert hot runner sensor requires comprehensive consideration of temperature range, accuracy requirements, installation space, response speed, and environmental conditions. Considering your high-temperature and high-humidity operating environment in Wuhan, the following are specific selection suggestions:
1. Define Temperature Range and Accuracy Requirements
If the process temperature is within the range of -40℃ to 1300℃, a K-type armored thermocouple is recommended, with an accuracy of ±0.4% or ±1.5℃, suitable for most injection molding scenarios.
For higher stability and anti-interference capabilities, the wrnk-187 PT100 sensor can be selected. It supports non-standard customization and is suitable for closed-loop systems with stringent temperature control accuracy requirements.
2. Match Installation Structure and Space Limitations
For confined spaces: Prioritize flexible K-type or J-type armored probe sensors for easy installation around the mold structure.
Solid Fixing Required: M6/M8 screw-type thermocouples are selected. Threaded fastening reduces contact thermal resistance and improves response consistency.
Multi-Point Temperature Measurement Needs: Customizable modular design with 1-50 units is available for centralized wiring and easy maintenance.
3. Optimized Environmental Adaptability: Given the high temperature and humidity in Wuhan, which can easily lead to a decrease in sensor insulation performance:
Select models with waterproof encapsulation and high insulation resistance (≥100 MΩ), such as SUPOT's standard industrial-grade armored products.
Perform regular insulation testing and cleaning to prevent magnesium oxide powder from absorbing moisture and failing, extending service life.
4. Consideration of Procurement and Maintenance Costs: SUPOT K-type sensors are priced at approximately 38.00 RMB per unit, offering excellent value and suitable for bulk replacement.
Non-standard customization services are supported. Parameters such as length and bending angle can be customized according to the hot runner layout to improve adaptability.
