Description:
Libratherm offers simple Digital Temperature Indicator Controller, which are low cost, accurate, rugged and
reliable instruments available for indication and On/Off control for general-purpose temperature control
applications. Indicators are available in display sizes of 0.5” to 4” to suit long distance visibility.
On/Off control is the simplest controlling method. When used for heating control the temperature sensed by
the connected sensor is compared with the set point and when the temperature exceeds this set point, the
heater is put OFF. When the temperature again drops below the set point, the heater is turned ON. So,
depending upon the heating system design, inertia due to heat, the heat absorption by process or the natural
losses, the temperature will oscillate above and below the set points by few degrees. When the application is
for cooling control, the cooling device such as compressor or water circulating valves are turned OFF, when
temperature drops below the set point and turned ON when the temperature rises above the set point.
Special models are available for applications requiring variable hysteresis i.e. where the single device to be
operated at two different set points. DIN rail mount temperature controller is also available as model LSC-120.
Some of the above models are also available in suitable size flameproof enclosures for use in the hazardous
environment.
