Important notes
Function
The conductivity transmitters are used as conductivity limiters and continuous blowdown controllers in
steam boilers in combination with the following equipment:
Conductivity controller LRR 1-51
Conductivity controller LRR 1-53
Industrial controller KS 90-1
Conductivity transmitters LRGT 16-1, LRGT 17-1
are mainly used in steam boilers with low TDS
content, e.g. steam regenerators, high-pressure boilers and condensate tanks.
Conductivity transmitter LRGT 16-2
is mainly used in industrial boilers up to PN 40 and
max. admissible conductivities of 6000 µS/cm in accordance with TRD/EN.
In steam and water boilers, conductivity transmitters/controllers can also be used to monitor the
condensate, feedwater and the water circuit for the ingress of acids, alkalis or seawater (EN 12952-7,
EN 12953-6, TRD 604, page 1).
Attention
The name plate specifies the technical features of the equipment. Do not commission or
operate any item of equipment that does not bear its own specific name plate.
Safety note
Danger
Steam or hot water can escape when the conductivity transmitter is loosened.
This presents a risk of severe scalding all over the body!
Therefore, only dismantle the conductivity transmitter when the boiler pressure is 0 bar.
The conductivity transmitter becomes hot during operation.
Risk of severe burns to hands and arms.
Make sure that equipment is cold before carrying out installation and maintenance work.
The equipment may only be installed, wired and commissioned by qualified and competent staff.
Retrofitting and maintenance work may only be performed by authorised staff who have achieved a
recognised level of competence through specific training.
