Temperature Sensors - Thermostats - Mechanical

The OHD5R-80B is a mechanical thermostat typically used in HVAC, refrigeration and other specialty applications where temperature needs to be monitored and controlled. It utilizes a spring-loaded bimetallic mechanism to control the temperature cut off. The bimetallic mechanism is made up of two different metals that expand and contract at different rates when heated and cooled. The bimetallic mechanism is mechanically linked to a switch which turns on or off as the temperature rises and falls.The OHD5R-80B has an adjustable setpoint which can be dialed in or changed to suit the application. This unit has a temperature range of -30 to 80°C and is capable of controlling large loads of up to 25A at 250VAC. The OHD5R-80b is also offered with a variety of temperature control options such as manual reset and differential control.The OHD5R-80B is designed to be used in applications where a large amount of power needs to be controlled, such as HVAC/refrigeration units, electric heating systems, mini-split air conditioners, and other specialty applications. It can also be used as a safety device to protect equipment from over-temperature situations.The OHD5R-80B is easy to install, requiring a few basic tools. The construction is robust and reliable and it is designed to fit in a variety of enclosure sizes. The unit is also very versatile as it can be used as a stand-alone unit, or integrated into larger control systems.The OHD5R-80B has a robust design and can withstand temperatures of up to 125°C, so it can be used in a wide range of applications. It is UL-rated and CSA-certified to meet all safety standards.The basic operating principle of the OHD5R-80B is simple: when the temperature falls below or rises above the setpoint, the bimetallic mechanism triggers the switch, which either turns the device on or off, depending on the application. It is also possible to use a differential control setting which turns the device on when the temperature falls below the setpoint, and off when it rises above a certain level.This device can provide an efficient and cost effective way to monitor and control temperature in any number of applications. It is also easy to install and maintain, making it an ideal choice for many different applications.
