Tips of Selection
The medium to be measured shall be compatible with the material contacting with the product. The code E, an additional functional code for selection, and intrinsically safe explosion-proof Ex ia II CT5 must be power supplied via safety barrier. Please contact us in case of the other special requirements and clearly indicate them when placing an order.
