Supplement 6 to the ATEX Certificate confirms that this model of sensor falls into
Category 1.
This sensor cannot be classified as Type 1 from the ATEX Certificate as the power supplied
by the isolator (45mW) is higher than the input power for Type 1 (34mW). Type 2 satisfies
input voltage, current and power considerations as well as giving a very conservative
ambient temperature limit of 52°C to achieve T6
The data collected from the ATEX certificates for use in 16115CAL002 and
16115CAL003 has been highlighted below.
