Leakage temperature monitoring for ATEX category II 2G Ex h IIC T4-T1 Gb X
Leakage temperature monitoring for ATEX
category II 2G Ex h IIC T4-T1 Gb X
The temperature of the leakage is monitored by a sensor
with measuring resistance PT100 EN 60751 of accuracy
class B, which is supplied as loose part. The sensor must
be installed in port U (cf. schematic and installation
1
drawings on the following pages).
Electrical data
Port on certified explosion-proof current circuits with the
following peak values:
▶ U = 30 V
i
▶ P
= 750 mW

The inner inductivity and capacity are small enough
to be neglected.

Notice – evaluation electronics for temperature
monitoring
The necessary evaluation electronics are not included
in the scope of delivery. The sensor must be operated
via an explosion-proof current circuit. The protection class
must be at least that of the sensor (see "Information
on explosion protection" on page 1).
