Silicone-free (for use in the automotive industry)
2.6 Safety equipment
This device is fitted with a rear wall or plug capable of being blown out. For a description, please refer to Chapter
6.3.4.
The window uses multi-layer safety glass.
2.7 Environmental protection
This device may optionally contain a filling liquid (e.g. glycerin or silicone oil). The provisions set out in the REACH
regulation on production and use of chemicals are to be respected, and the relevant safety data sheets from the
manufacturers of the chemicals are available on our website for download.
3 Use in explosion risk areas pursuant to Directive 94/9/EC (ATEX)
3.1 T5500/T6500 without switching contact
Area of use:
Explosion risk areas Zone 1 and 2, and 21 and 22, risk from gases and dry dust
Permitted temperatures:
Permitted ambient temperature -25°C to +60 °C.
Permitted medium temperature in the pressure gauge depends on the working conditions, not on the gauge design.
Warning! With gaseous media, the device temperature may increase due to compression heat. In
such cases, the rate of the pressure change must be regulated or the permitted temperature of the
measuring medium reduced.
Note:
To avoid additional temperature increase, the devices should not be exposed to direct exposure to sunlight when in
operation!
The effects of impact are considered as negligible.
For the non-electrical part of the devices, the standards EN 1127-1 (2007), EN 13463-1 (2009) and EN 13463-5
(2011) are applicable with regard to explosion protection. The relevant requirements of these standards are satisfied.
The documentation has been filed with TÜV-Nord-Cert (see declaration of conformity).
Labeling:
II 2 GD c IIC Tx
3.2 T5500/T6500 I#### with inductive proximity switch KE##I##0C0H2
Area of use:
Explosion risk areas Zone 1 and 2, risk from gases
Permitted temperatures:
The maximum occurring surface temperature of 95 °C was determined with no covering of dust and with no safety factor.
Permitted ambient temperature -25 °C to +49 °C.
Permitted medium temperature in the pressure gauge ≤ 45 °C.
Warning! With gaseous media, the device temperature may increase due to compression heat. In
such cases, the rate of the pressure change must be regulated or the permitted temperature of the
measuring medium reduced.
Note:
For a change in differential pressure between 10 % and 90 % of the measuring range and a pulse frequency of <
0.06 Hz, the temperature increase is <10 K.
