Device with RIA15
The RIA15 remote display (for Ex or non-Ex area) can be ordered together with the
device. See the Product Configurator.
Compensation of the atmospheric pressure must be ensured for the installation. A black,
vented cable gland is supplied for this purpose.
The RIA15 process indicator is loop-powered and does not require any external power
supply.
The voltage drop to be taken into account is:
• ≤1 V in the standard version with 4 to 20 mA communication
• ≤1.9 V with HART communication
• and an additional 2.9 V if display light is used
