Discover advanced high-temperature thermal protection with Limitor TB97/TB98 thermal switches, featuring Bimetal Snap-Disc technology, heat-resistant ceramic housings, automatic reset, and switching temperatures up to 450°C. Explore technical specifications, industrial applications, and key selection criteria for engineers and OEM manufacturers.
Modern HVAC/R and Thermal Management systems require more than temperature control alone. This article explores how Temperature Sensors, Pressure Transducers, Thermostats, and Thermal Motor Protectors work together to provide Measurement, Control, and Protection, including a practical Case Study for an electronic cooling system in a specialty vehicle.
How do you choose a Temperature Sensor for military and rugged applications? This engineering guide covers NTC, RTD and Thermocouple selection, R/T curves, probe design, threads and MIL-DTL-38999 connector interfaces, including a real-world Custom Temperature Sensor case study featuring a 30kΩ NTC and Souriau 8D connector.
Do you really need to measure temperature – or do you simply need to know when it is time to take action?
In many overtemperature protection applications, a Temperature Switch can provide a simpler and more direct solution than a complete temperature measurement system. This article explains the difference between Temperature Sensors and Temperature Switches, how bimetal thermal switches work, when to choose NC or NO, and why installation location, switching temperature, and thermal response are critical to effective protection.
An autonomous combat aircraft is not simply a fighter with the pilot removed. From Tactical IMUs and GNSS-denied navigation to position feedback, temperature sensing, power monitoring and Edge AI, discover how the aircraft’s “nervous system” provides the reliable real-time data required for autonomy, fault detection and mission-aware decision-making.
Temperature monitoring in Battery Packs is not limited to electric vehicles. An NTC sensor mounted directly on a battery cell can help the BMS detect Hot Spots, monitor temperature differences and support effective thermal management. This article examines the Variohm Eurosensor ETP-ST-21-35-B57861S0103A039, an NTC 10K Sleeve Temperature Sensor designed for cylindrical cells, and explores its relevance to UAVs, robotics, defense systems, ESS and industrial applications.
Think your PT100 sensor has failed because your PLC is displaying the wrong temperature? The problem may not be the sensor at all. This article explains the differences between RTD, PT100, PT1000, thermocouples, and thermistors, compares 2-wire, 3-wire, and 4-wire RTD connections, and demonstrates how cable resistance alone can introduce temperature errors of several degrees. Learn how to select the right RTD sensor, probe construction, and wiring method for accurate and reliable temperature measurement.
Most thermal protectors disconnect a circuit when it overheats – but what happens when the system cools down? In many applications, the automatic restart itself can become the biggest risk. Learn why overheating is often just a symptom, when auto-reset protection isn’t enough, and how latching protection can prevent repeated failure cycles, equipment damage, and safety hazards.
Is measuring pressure alone enough? Discover why more engineers are combining pressure and temperature measurements to gain a more complete understanding of system behavior, improve diagnostics, and increase long-term reliability.
The temperature sensor showed 80°C. The reading was completely accurate. The motor still burned out. Why? Because in thermal protection, the most important question is not how hot it is—but where you are measuring. Discover how VARIOHM temperature sensors and LIMITOR thermal protection devices help engineers improve reliability, prevent overheating, and protect critical systems.
