Tips for Type Selection

1. The medium measured shall be compatible with the material contacting with the product.
2. As an additional function code for type selection, the code “E” for intrinsically safe explosion-proof type Ex ia II CT5 denotes that power source must be supplied via safety barrier.
3. For other special requirements, please discuss with us and clearly indicate them in the order.
