About this operating manual
This operating manual has been prepared in accordance with the product-specific and
application-relevant specifications from legal requirements, provisions, regulations, technical
standards, guidelines and conventions.
EU - Type Examination Certificate BVS 17 ATEX E 110 X
IECEx Certificate of Conformity BVS 17.0091X
This operating manual allows the user to become familiar with the design and function of the
temperature sensors.
1.2
Purpose/function
The listed temperature sensors with cable for operation in hazardous areas are used for
measuring process temperatures in solid, liquid and gaseous media.
NOTE
The approval is based on the power supply with only one intrinsically safe electrical circuit, which means
that a double sensor is also supplied by only one intrinsically safe electrical circuit.
The temperature class classification depends on the ambient temperature of the connection point
and the electrical characteristics of the intrinsically safe electrical circuit
(U
0
, I
0
and P
0
) with which the sensor is powered and it is described in the following operating
instructions for the different operating conditions.
The standard ambient operating temperature of Ex devices ranges from -20°C to +40°C, unless
otherwise specified by the manufacturer and special codes are not required.
Different atmospheric conditions (e.g. temperatures) are described in the operating instructions
with the applicable operating conditions.
The standard specified safety factor (see DIN EN 60079-0, Sec. 26.5.1.3) for calculation of the
process temperature of less 5 K for temperature classes T6 to T3 (or the characterised
temperatures ≤ 200 °C) and less 10 K for temperature classes T2 and T1 (or the characterised
temperatures ≥ 200 °C) is already taken into account in the following calculations.
