Narrow Differential Thermostats

Our teams at Calco Electric provides customers with high-quality Narrow Differential Thermostats. These thermostats are typically used in industries that need accurate heat treating ovens.

Extreme Precision from Calco Electric

Because these thermostats are integral to industries, they must be especially precise. To do this, the narrow differential thermostat must turn on and off at closer tolerances. This means that its differential is more narrow, making the heat turn on and off more rapidly.

Narrow Differential Thermostats use snap action with bimetal discs to open and close the contact. Bimetal discs are made of two different kinds of metal, with one loosening faster than the other. This places tension inside the thermostat, disconnecting the contact that keeps the heat turned on.

The bimetal thermal switch is a 17AME-H. Its lowest temperature is from 0°C to 180°C. It is particularly designed to handle lighting, heating, and motors. Engineers made the switch to concentrate on small temperature differential (called the narrow differential) and the low-temperature range.

With the bimetal heat expanding and the cold contracting, the thermal switch is able to turn on and off. This allows the element to control the area’s temperature within a small range of heat.

The narrow differential thermostats from Calco Electric include:

  • 100% regulated temperature
  • Snap action as well as creep action
  • Personalized wire length and type
  • 100% RoHS Compliant
  • 100,000 life cycles for long-term capacity
  • Personalized terminals located at the same or opposite ends

This Bimetal Thermal Switch from Calco Features Lowest Temp of 0°C - 180°C
17AME-H series bimetal thermal switch is specially designed for heating, lighting and motors. The switch is focused on the low temperature range and small temperature differential also known as narrow differential. Based on the principle of bimetal heat expansion and cold contraction, the thermal switch can control the temperature of application under a very small range.
