Flowserve LRGT16-1 Spector compact Conductivity Transmitter System - Manual (Page 4)

Important Notes
Safety Note
Use conductivity transmitter system LRGT 16-1 only for monitoring electrical conductivity
in liquids.
The equipment has to be supplied with 24 V DC from a safety power supply unit (PSU) in
accordance with DIN VDE 0106 (safe supply isolation). The PSU must be equipped with
an overcurrent protective device according to DIN EN 61010-1/VDE 0411.
The transmitter system LRGT 16-1 must only be installed by qualified staff.
Qualified staff are those persons who - through adequate training in electrical engineering,
the use and application of safety equipment in accordance with regulations concerning
electrical safety systems, and first aid & accident prevention have achieved a recognised
level of competence appropriate to the installation and commissioning of this critical safety
device.
Danger
When loosening the conductivity transmitter system steam or hot water might escape. This
presents the danger of scalding. It is therefore essential not to dismantle the conductivity
transmitter system unless the boiler pressure is verified to be zero.

System Description
The LRGT 16-1 is a compact-design conductivity transmitter system consisting of a
conductivity electrode, a temperature sensor for detecting the fluid temperature and an
integrated conductivity transmitter. The equipment works according to the conductivity
measurement two-electrode control principle and provides a conductivity-dependent and
temperature compensated measuring current of 4 - 20 mA.
The conductivity transmitter system is designed to measure the electrical conductivity in
conductive fluids.
If the LRGT 16-1 is connected to the industrial controller type KS 90 the equipment can be
used as conductivity limiter and/or continuous blowdown controller in steam boilers,
(pressurised) hot-water boilers and condensate systems.
