Temperature Sensors – Thermostats – Solid State

Today’s highly integrated modern control systems rely on sensors to accurately detect temperatures. Productivity and safety are further optimized when the output of the sensors are integrated into control systems such as relays, controllers, and/or HVAC systems. The TC620CVOA713 is a solid state thermostat ideal for temperature sensing in industrial, medical, and consumer applications.

The TC620CVOA713 is a hermetically sealed metal can thermostat configured to open on temperature rise. This means that when the sensed temperature rises above a certain calibrated threshold the internal contacts open. The resulting current flow is sensed by integrated circuits and provides a reliable temperature feedback.

This solid state thermostat is a rugged device designed to provide maintenance free operation. The operating range of the device is -50C to +290C. This range covers most temperature sensing requirements, allowing for a wide variety of application, from medical to industrial. In addition, the device is well suited for DIN rail mounting, making installation and integration with other systems easy.

The TC620CVOA713 is a thermally activated device that operates by way of a bimetal element. When the element senses a temperature increase, the metal expands, causing contact closure between two, normally open, metal contacts. The metal element and contact closures are used to provide a temperature feedback signal.

Internally, the device contains a thermal system composed of a bimetal element, embedded in a ferromagnetic material. The element is further thermally coupled with a flat plunger and a cearcam. When the sensing element detects a temperature increase, it changes shape, causing the plunger to expand, injecting a current pulse into the cearcam. The cearcam is then able to transmit this signal output to the integrated circuits, which feed the output signal to a system controller.

The TC620CVOA713 is ideal for applications in which precise temperature sensing and stability are needed. For example, it could be used to control a boiler in a factory, or temperature regulation in the medical environment where the risk of infection is important to monitor. Its high accuracy and low power consumption also make it an ideal device for use in data centres and server rooms for temperature regulation.

The TC620CVOA713 is a high quality, reliable solid state thermostat with a wide range of applications. Its accuracy, stability, and robust design make it an invaluable asset for many applications. Further, its use in remote sensing applications allows for an added layer of safety where it is not possible to directly observe the temperature but is still important to monitor.
