13 . Safety, protections, compatibility and explosion proof
The level sensor is equipped with protection against electric shock on the electrode, reverse polarity,
output current overload, short circuit and against current overload on output.
Protection against dangerous contact is provided by low safety voltage according to EN
33 2000- 4- 41. Electromagnetic compatibility is provided by conformity with standards EN 55022 / B,
EN 61326-1, EN 61000-4-2 to -8.
Explosion proof DLM–35Xi (XiT, XiM, XiMT) is provided by conformity with standards EN 60079-0,
EN 60079-11, EN 60079-26.
Explosion proof DLM–35Xi (XiT, XiM, XiMT) is verified FTZÚ – AO 210 Ostrava – Radvanice:
FTZÚ 16 ATEX 0140X.
A declaration of conformity was issued for this device in the wording of Act No. 90/2016 Coll., as
amended. Supplied electrical equipment matches the requirements of valid European directives for
safety and electromagnetic compatibility.
Special conditions for safe use of variant DLM–35Xi (XiT, XiM, XiMT)
Level meters DLM-35Xi(XiT, XiM, XiMT) are intended for connection to approved spark-safe power
supply unit circuits (of insulating transducers) with galvanic separation. In the event that devices
without galvanic separation are used (Zener barriers), it is necessary to balance the potential
between the sensor, resp. level meter and the barrier grounding location.
The limit output parameters of spark-safe units (insulating transducers) must correspond to the limit
input parameters of the level meter. When assessing spark-free safety of circuits, it is necessary
to also take into consideration the parameters of the connected cable (namely its induction and
capacity).
The DLM-35Xi configuration may be located in zone 0 or zone 20. With the DLM-35XiT configuration
it is only possible to located the electrode part in zone 0 and in zone 20, and then the head with the
electronics in zone 1 or zone 21.
Ambient temperature: Tamb = -40°C to +75°C.
The temperature of the measured material according to the variant configuration, see chapter
"Technical parameters". The maximum temperature of the electrodes equals the temperature of the
measured material.
Variant DLM–35XiMT it is necessary to observe that temperature of any surface of apparatus,
when coal dust can from a layer, do not exceed 150°C.
