Reliable function
The temperature between the rotor and the stator is thermo-
electrically recorded constantly by a temperature sensor, which
is built into the stator, and compared to the limit set
on the dry-running protection (TSE) control device.
If the pump runs dry, the temperature rises due to the in -
creased friction between the rotor and the stator. When the
temperature set point is reached, the control device switches
off the pump drive and triggers an alert.
Universally applicable
Regardless of the pipeline routing and the way the pump is
setup, this reliable function is available not only for water, but
also for abrasive, highly-viscous, and sticky media, including
media with a tendency for coating or settling.
The TSE control device, with its potential-free relay contacts, is
integrated in the protective circuit of the drive and connected
to the temperature sensor built into the pump. The pump’s
switch off temperature can be adjusted using the keyboard at
the front. An alert triggered by excessive temperature is
indicated by a red LED.
The basic version of the dry running protection (TSE-LC)
switches off the drive motor of the pump via a contact if a
preset, non-adjustable limit value is reached. Because of the
fixed limit value there is no control unit required with this
design.
Special designs
In addition to the TSE control device, the ready-for-operation
motor control contains all the components required for reliable
operation. All that remains to be done during installation is to
establish the connections for the power supply, electric motor
and temperature sensor.
The dry running protection can optionally be delivered with a
connection for a contact pressure gauge, to protect the con-
nected pump from excessive pressure. For explosive areas the
TSE can optionally be delivered in the ATEX or an intrinsically
safe design. The TSE controller is approved by both UL and
CSA for North American users.
