Many applications requiring a fixed temperature set point have relied
on mechanical thermostat devices (thermostats) for thermal control.
But, thermostats are inadequate for many applications because of the
long-term reliability issues such as 100,000 cycle rating and poor
temperature control.
The SERIES EHG® thermal solution includes a compact
precision temperature control, thermocouple sensor and power switching
device integrated into the flexible heater's power cord. The SERIES EHG
reduces system costs and substantially extends the life over
conventional thermostat solutions.
The evolution of miniature microprocessor technology and Watlow
switching technology allowed the development of a small versatile
precision temperature control and thermocouple sensor that can be
integrated with Watlow silicone rubber heater products. This device
senses the temperature via input from a thermocouple strategically
placed on the heater mat. The microprocessor is programmed prior to
shipment with the customer's application specific set point. This
results in quick delivery of a custom integrated system.
The small mass of the thermocouple provides superior response to
changes in process temperature and allows for higher watt density
silicone rubber heater designs. Depending on the specific application,
Watlow's power switching design can extend life up to 40 times greater
than thermostats. These features result in an integrated custom set
point temperature control product with superior life span, faster
heat-up rates and improved accuracy. The SERIES EHG system has been
tested to over four million cycles at rated amperage.
