Description
The level transmitter NRGT 26-1 / NRGT 26-1 S is a compacttype system consisting of a level measuring electrode and a
level transmitter integrated in the terminal box.
The level transmitters NRGT 26-1 and NRGT 26-1S are
used for continuous level monitoring in steam boilers and
(pressurized) hot-water installations or in condensate and
feedwater tanks.
In conjunction with the level switch NRS 2-.. and the level
controller NRR 2-.. the transmitter can be used as water
level controller with MIN/MAX alarm.
The level transmitter can be used in combination with the
following level switches and controllers: NRS 2-50, NRS 2-51,
NRR 2-50, NRR 2-51, NRR 2-52 and NRR 2-53.
Function
The level transmitter works according to the capacitance
measurement principle and translates the level changes
into a level-dependent current signal of 4-20 mA, with
the length of the electrode rod determining the measuring
range.
The level transmitter is installed inside steam boilers, vessels or in an external level pot. If the equipment is installed
inside the boiler or vessel, a protection tube provided on
side ensures correct functioning.
The level transmitter can be installed together with one
GESTRA level electrode for water level limiting or for highlevel alarm in a single protection tube or an external level
pot.
The level transmitter can be used in electrically conductive
and non-conductive fluids.
