Description
The conductivity electrodes LRG 16-40, LRG 16-41, LRG
17-40 consist of a TDS (= Total Dissolved Solids) monitoring
electrode for conductivity measurement, a temperature sensor
for detecting the fluid temperature and a conductivity transmitter that is fully integrated in the terminal box.
The conductivity electrodes LRG 16-40, LRG 17-40 work
according to the conductometric measurement principle and
use two electrodes. The conductivity electrode LRG 16-41
also uses the conductometric measurement principle but
works with four electrodes. All three electrode types monitor
the electrical conductivity of electrically conductive fluids.
Together with the TDS controller LRR 1-40 and an operating
device type URB or SPECTORcontrol the conductivity electrode LRG can be used as conductivity limiter and continuous
blowdown controller in steam boilers and (pressurized) hot
water plants or as conductivity meter in condensate and
feedwater systems.
The conductivity electrodes LRG 16-40, LRG 17-40 are
particularly well suited for steam boilers with low TDS
content, e.g. in steam regenerators, high-pressure boilers
or condensate vessels.
The conductivity electrode LRG 16-41 is designed for industrial
boiler plants up to PN 40 and max. admissible conductivities
of 8000 / 6000 μS/cm according to TRD/EN.
The data exchange between the conductivity electrode LRG,
the control and operating equipment and other devices is
effected by the CAN bus to ISO 11898, using the CANopen
protocols. Technical Data
Test approval no.
