Tips of Selection1. The measured medium shall be compatible with the material contacting with the product.
2. The code E, an additional function code for selection, namely, intrinsically safe explosion-proof Ex iaIICT6, must
be power supplied via safety barrier.
3. Please contact us for other special requirements and clearly indicate them in the order.
4. During the field installation of flat diaphragm, the correct sealing method shall be adopted to prevent the
installation stress influencing product stability.
