E.G.O produce a variety of limit thermostats
in various shapes, sizes and materials so that they can supply
exactly the right single pole limit thermostat (or. Thermal Cut
Out - TCO) for every appliance. The
single pole limit thermostat can be supplied with many different
capillary tube lengths, which makes them extremely flexible to
install. The single will detect the temperature of the medium,
while the housing can be positioned in the most suitable
location.
E.G.O single pole limit thermostats are
manufactured using high quality stainless steel tube and are
suitable for high ambient temperatures.
Above is a typical E.G.O
Limit Thermostat, with a manual reset button - Type:
55.135series.
Above is a typical E.G.O
Limit Thermostat, with a manual reset button - Type:
51.series. This single pole limit thermostat is generally
used on old appliances and is not normally offered for new
applications.
With the design of this
device aimed towards greatest flexibility, E.G.O single pole
limit thermostats (TCO's) can be delivered for every appliance.
It is always strongly recommended that this device be fitted in
conjunction with a control thermostat.

The single pole limit thermostat can be
fitted with following features, which can differ according to
the customers application.
◊ Temperature range
◊ Capillary tube length
◊ Sensor shape
◊ Sensor dimensions
◊ Insulation sleeve length
◊ Accessories, glands, etc...
◊ Functions - Normally closed
Operation
A temperature sensor consists of a sensor,
capillary tube (0.5mm I/D), diaphragm and filler medium. The
filling medium heats up in the sensor and expands, thus
increasing pressure in the closed system. When the pressure
achieves a defined level, the diaphragm actuates the snap-action
switch that either opens or closes the electrical circuit.
The single pole limit thermostat (TCO)
have a very short working stroke. A distance of 0.01mm at the
diaphragm corresponds to a temperature change of approximately 3
Kelvin in the oven, for example. This requires extremely high
precision production.
The New Type 56.105series
The Type: 56.105series is the
latest and most effective single pole limit thermostat E.G.O
have produced. This model has trip free security, which prevents
tampering of the manual reset button and also has a pressure
sensitive fail safe system, which breaks the electrical circuit
if the capillary is accidentally damaged.
Note: For advise on selecting the
correct thermostat for a new or existing application, please contact our
office for technical advise.
