Description
The XB-ATEX sensorbox is an extra robust, pressure-, saltwater- and corrosion-proof stainless steel housing with integrated sensor or sensors and electronic systems as described for the SB series sensor casings. An impermeable cable gland and compact stainless steel housing size enable the use of this high quality measuring system in especially harsh operating conditions.
In these ATEX versions of the XB, the sensor(s) and most of the electronics are encapsulated with silicone potting, and a special cable gland is used. They are delivered with cable attached. Each XB-ATEX undergoes individual testing by an external service provider.
Application
Like the XB, the XB-ATEX housing is used for taking precise inclination or acceleration measurements under harsh operating conditions. Additionally, it is used in environments with an increased risk of explosion from gases or dust, such as offshore, mining, in petrochemical and agricultural applications. 0.5V ... 4.5V and 4...20mA are among the possible output signals.

typical use

Description of the device
The XB.. can be used as a sensorbox for inclination or acceleration sensors. It can be used in potentially explosive atmospheres due to gas or dust in Zone 1 (21) and 2 (22) as well as in underground mining (EPL Mb). The housing is pressure-resistant and dust-tight (IP6X), and is made of stainless steel. It is connected via an approved Ex-d cable gland.
Electrical specifications
Voltage: up to 30V
Max. power dissipation: 8W
Special conditions
Ambient temperature range: -40°C to +60°C
Only cables and cable glands specified by the manufacturer may be used.
For use in areas at risk of dust explosions, the device can be operated with a dust layer of up to 50 mm.
Important general information
