As outlined by Upkeep in their article, “6 Types of Temperature Sensors Defined and Use Cases,” temperature sensors are essential devices in both everyday and industrial applications, allowing for precise monitoring of heat conditions that keep systems functioning optimally. Beyond common HVAC uses, these sensors are integral to industrial machinery, where they monitor ambient conditions, log temperature data, and detect fluctuations crucial for safe operation. Connected to larger CMMS networks, these sensors can either be wired or wireless, enabling accessible and continuous monitoring.
Temperature sensors come in a variety of types, each suited to different applications. Among the six main types, thermocouples are highly durable and cost-effective, capable of measuring across broad temperature ranges through voltage differences, though they offer lower accuracy. Infrared sensors are another versatile option, capable of detecting heat signatures in machinery with minimal power usage and a compact design. These sensors are ideal for scenarios requiring portable, efficient temperature monitoring.
The familiar thermometer measures the temperature of fluids, gases, or solids and is indispensable for both comfort and safety. For more specialized applications, silicon diode sensors can track extreme temperature fluctuations, as seen in industries working with rocket fuel or similar materials. These are essential in applications where failure to monitor extreme temperatures could lead to critical failures.
Two other highly precise sensors include resistance temperature detectors (RTDs), which link temperature with resistance changes to achieve high accuracy, and negative temperature coefficient (NTC) sensors. NTC sensors are designed to decrease resistance as temperatures rise, making them reliable in specific, high-stakes environments.
