1. Dew Point Transmitter - New Polymer Thin Film Sensor Technology
2. High precision chip/stable anti-interference/protection level IP65
3. Application scenarios
In large warehouses, agriculture, laboratories, industrial manufacturing, large warehouses, etc
4. Thermosetting polymer polymer sensitive capacitor
The low humidity sensitivity should exceed that of ordinary humidity sensitive capacitors by more than a hundred times
5. The sensor uses a humidity sensitive capacitor as the core component, which can sense the moisture content of air in extremely low humidity. After multi-point compression and temperature correction, it ensures the reliability of the test,
Accurate measurement results are available in various environments, which are then converted into current signal outputs.
6. Stainless steel probe housing
Waterproof and dustproof, high temperature resistance, corrosion resistance, good density, fast response speed
Low requirements for usage environment, IP65 protection level
Even in harsh environments, it can provide good protection
Stainless steel probe housing (default line length 1 meter)
