Description
The compact-design conductivity transmitter LRGT 16-1,
LRGT 16-2, LRGT 17-1 consists of a conductivity electrode, a
temperature sensor for detecting the fluid temperature and a
conductivity transmitter unit incorporated in the terminal box.
The conductivity transmitters LRGT 16-1 and LRGT 17-1 work
according to the conductometric measuring method using
two measuring electrodes and the conductivity transmitter
LRGT 16-2 works according to the conductometric measuring method using four measuring electrodes. The equipment
measures the electrical conductivity of electrically conductive
fluids (TDS = Total Dissolved Solids content) and provides
a 4-20 mA measuring current as a function of the detected
conductivity value.
Conductivity transmitters are used in combination with the
following equipment as conductivity limiters and continuous
blowdown controllers in steam boilers: Conductivity controller LRR 1-51, LRR 1-53 and industrial controller KS 90-1.
Conductivity transmitters can also be used as conductivity
monitoring equipment in condensate and feedwater systems.
The 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 or condensate tanks.
The conductivity transmitter LRGT 16-1 is also approved for
feedwater monitoring on ships.
The conductivity transmitter LRGT 16-2 is mainly used in
industrial boiler plants operating with pressures up to PN
40 and max. admissible conductivities acc. to TRD/EN of
6000 ?S/cm.
