The case of the sensor has independent chambers for
electronic items and for the connecting terminal board. Both
chambers are provided with lids that can be screwed. The
cable outlet for the connecting wiring and the plug are
delivered pursuant to the design of the sensor as accessories.
The terminal board of the sensor is accessible after
unscrewing of the lid.
On the case, the sensor is provided with external terminal for
the connection of the grounding wire or wire for mutual
interconnection.
The sensor is supplied from an external source and it is set-up
to the required range at the manufacturer of the sensor.
The pressure probe consists of the separating membrane. The
sensor is equipped with HART communication.
T E C H N I C A L D A T A
The sensor is designed pursuant to ČSN EN 61140 ed. 2 as
electrical equipment of protection class III for the application
with the category of the rated impulse lasting voltage II and the
pollution grade 2 according to ČSN EN 61010-1 ed. 2; the
follow-up (evaluation) device shall correspond to Article 6.3 of
the said standard.
Protection against electric shock is ensured by power supply
from a safe source of
according to ČSN 33 2000-4-41 ed.2.
Resistance to short circuit is permanent; in case of reversing
the poles, the sensor without is damage but also without
function.
