Klay recently obtained the intrinsically safe certification for the new series 4000 and DP-4000. This means there are now both ATEX and IECEx certifications on all transmitter series.
For the Series 2000 also certification for a Dust environment (ia) and Ex-nA (zone 2) is available. An important factor for all certifications is the ambient and process temperature.
There is a new selection table showing all possibilities and temperature classes regarding explosion safety. Easy to select the right instrument with the certification you need.
