5.7 Environmental conditions
Climatic rating:
Standard version
Temperature – 25 to + 70 °C [-13...158 °F]
Annual mean relative humidity ≤ 90%
or
Version with improved climatic rating
Temperature – 40 to + 70 °C
[-40...158 °F]
Annual mean relative humditiy
≤ 95%
Ex version
Temperature – 40 to + 55 °C [-40...131
°F] at T6
resp. – 40 to + 70 °C [-40...158 °F] at
T5
resp. – 40 to + 75 °C [-40...167 °F] at
T4
Transportation and
storage temperature: – 40 to 80 °C [-40...176 °F]
Altitude:
2000 m max.
Permissible vibration:
(without addit. gear): 0...200 Hz,
10 g continuous, 15 g for 2 h
200...500 Hz,
5 g continuous, 10 g for 2 h
3 × 50 g every 10 impulses
Shock:
in all 3 axes
Permissible static
load on the shaft:
Max. 1000 N (radial)
Max. 500 N (axial)
If subjected to vibration the shaft load
should be as low as possible to ensure
optimum life of the bearing
5.8 Operation in potentially explosive environments:
Gas explosion
prevention:
Labeling:
Conform to standard: ATEX:
Type of protection:
Temperature class:
Group according to
EN 60079-00:2012: II
• The operation in other explosive atmospheres is not
permissible.
• It is not permissible to make any alteration to equipment
that is used in potentially explosive environments.
Devices with explosion prevention must be
operated in accordance with the stipulations
of the operating instructions. The relevant
laws, regulations and standards for the
planned application must be observed.
6. Mounting
The twelve versions of the transmitter differ in their mechanical
design. Four of them are intended for mounting directly on
the device being measured. The others are equipped with a
mounting bracket or a fl ange. The relationship between the
three types of mounting, or more precisely the corresponding
cut-out diagrams and the different versions of the transmitter

Transmitter
versions
The M6 screws are needed for the "directly" mounted versions
and four M8 nuts and bolts for those "with a bracket" or
"with a fl ange". The screws, respectively nuts and bolts are
not supplied, because the required length varies according
to the thickness of the mounting surface.
When deciding where to install the transmitter
(measuring location), take care that the ambient
conditions given in Section 5 "Technical data"
are not exceeded.
