AC90ABD

AC90ABD is a type of temperature sensing device, particularly, a mechanical thermostat. It is designed to regulate temperatures, providing comfort and energy savings for a variety of applications.

A thermostat is a simple device that senses temperature and automatically adjusts a control system, to achieve an accuracy of ±0.5°C. In a typical HVAC (Heating, Ventilation and Air Conditioning) system, the AC90ABD thermostat is installed in the return air duct, usually near the entry to the blower compartment. This helps to ensure a consistent and accurate temperature throughout the system.

The AC90ABD thermostat works on a basic principle of using symmetrically balanced bimetallic strips. The bimetallic strip changes its shape when it is exposed to temperature changes. The change in shape is used to open and close a set of contacts, or switches, which in turn control the flow of power to the HVAC equipment.

The advantages of using an AC90ABD thermostat are many. One of the main advantages is its low cost. Unlike more expensive digital or electronic thermostats, the AC90ABD is very affordable. This makes it an excellent choice for budget-conscious consumers. Additionally, since it is a mechanical device, it is very reliable and requires little maintenance.

Another advantage of the AC90ABD is its wide range of applications. It can be used for controlling temperatures in a variety of HVAC systems, from commercial buildings to residential homes. It can also be used in industrial machinery, such as ovens, dryers, and more. Additionally, it is commonly used in refrigeration and air-conditioning systems.

In conclusion, the AC90ABD thermostat is a versatile and reliable mechanical temperature sensing device. It is perfect for a wide range of applications, from residential and commercial buildings to industrial machines, and offers great performance at an affordable price.
