Temperature Sensors - Thermostats - Mechanical are essential in many applications. The OHD3-100M, specifically, is an adjustable hybrid, temperature-sensing device that offers both over-temperature protection and temperature monitoring. It is a useful tool for ensuring thermal protection for many applications. The following sections outline the application fields and the working principle of the OHD3-100M.

Application Field
The OHD3-100M is a temperature-sensing device that is mainly used in electrical enclosures, cabinet cooling systems, and industrial equipment. It is most commonly used for controlling the on/off cycles of the cooling fans within an electrical enclosure. It is also used to regulate the flow of cooling air within a cabinet cooling system as well as measuring temperature-sensitive components in industrial equipment. The OHD3-100M is rugged, reliable, and features adjustable set-point temperature ranges in order to adapt to a wide variety of conditions. It has a wide operating temperature range of -40°C to +120°C, making it suitable for a variety of applications.

Working Principle
The OHD3-100M is a potentiometric device that uses a thermistor to detect the temperature of the ambient environment. The thermistor is a resistive element that changes its electrical resistance with changes in temperature. As the temperature increases, the resistance of the thermistor decreases proportionally. The thermistor is connected to a voltage divider circuit, which is composed of two resistors and a potentiometer. The two resistors in the circuit act as a reference voltage, and the potentiometer is used to adjust the resistance of the thermistor. This circuit is linked to a pair of contacts, which are connected to a switch. As the temperature increases, the resistance of the thermistor decreases, which increases the voltage that is applied to the switch. This change in voltage results in a change in the position of the switch, which activates the contacts.

The OHD3-100M is a versatile temperature-sensing device that can be used for a variety of applications. It is designed to ensure thermal protection and temperature monitoring, making it a useful tool in many different industries. It is a reliable and economical tool that can be used to regulate temperature-sensitive components, monitor thermal protection, and much more. With its adjustable set-point temperature range, the OHD3-100M can be adapted to a wide variety of conditions and environmental factors.
