4.2 Protective casing
The protective casing, available as accessory (Part No. 2350-xx), may not be used in potentially explosive
atmospheres because electrostatic charging can occur.
4.3 Sensors
All temperature and humidity sensors supplied by ELPRO-BUCHS AG are passive elements and consequently
can be used in potentially explosive atmospheres without any problems.
4.4 Sensor Cable
In accordance with directive EN 60079-11, all sensor cables which are used in potentially explosive atmospheres
must be marked at their connector side or connection side respectively. The best way to mark the cable is to
use a piece (approx. 5 cm) of light blue shrinkdown tubing.
The supplier marks the cable as part of the order when the customer gives the appropriate directions. The
customer may also mark the cable when a sensor is replaced. We recommend the use of the following
material: shrinkdown tubing light blue supplied by Raychem, e.g. Part No. RNF-3000-R-6/2-6.
4.5 Data Cable
For reasons of safety, we recommend that you read out and evaluate logger data outside the dangerous area.
