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.
Most systems do not fail suddenly. Filters clog gradually, pumps lose efficiency over time, and vacuum systems drift out of specification long before a fault alarm appears. In many cases, the earliest warning sign is not temperature, vibration, or power consumption – it is a subtle change in differential pressure (ΔP). This article explains why Differential Pressure is one of the most valuable indicators of developing failures, how Pressure Switches, Vacuum Switches, and Differential Pressure Switches are used for early fault detection, and why the most important parameter in your system may not be pressure itself, but the small change that appears long before the failure becomes visible.
Temperature measurement is no longer only about selecting RTD, Thermistor or Thermocouple technology.
In many industrial, medical, defense and Semiconductor applications, the probe mounting configuration itself directly affects response time, thermal stability, accuracy and long-term reliability.
This article explores the engineering differences between Ring Terminal, Screw-In, Surface and Tubular Temperature Probes, common installation mistakes that create thermal lag and instability, and how Variohm and Limitor temperature probe solutions help optimize real-world thermal measurement performance.
AI is transforming data centers from simple server rooms into highly complex thermal and electrical infrastructures.
As rack power densities rise from 5kW to 100kW, traditional cooling and protection methods are no longer sufficient.
From Airpax circuit breakers and thermostats to Variohm sensors and industrial power solutions, we examine how next-generation AI facilities depend on tightly integrated cooling, sensing and power management systems to maintain uptime and operational stability.
Non-contact rotary position sensors are rapidly becoming the preferred solution for modern industrial, robotics, and defense systems. This article explores how Hall Effect and Inductive sensing technologies work, why traditional potentiometers are reaching their limits, and which real-world integration challenges – including vibration, EMC, sealing, and mechanical loading – can determine long-term system reliability even when the datasheet looks perfect.
Linear position sensors are widely used across industrial, automotive, and control systems – but selecting the right one is more complex than choosing a stroke length. In this article, we explore how mechanical design, environmental conditions, and system-level integration affect sensor performance, and why many real-world failures are caused by installation and application mistakes rather than the sensor itself.
Industrial temperature sensors play a critical role in monitoring and protecting industrial systems. This article explains the engineering challenges behind accurate temperature measurement, common mistakes in sensor selection, and how VARIOHM temperature sensing solutions provide reliable measurement as part of a complete system architecture.
Industrial pressure sensors are essential for monitoring and control in hydraulic systems, industrial machinery and advanced equipment. This article explains the real engineering challenges behind pressure measurement, common mistakes in sensor selection, and how VARIOHM pressure sensors deliver reliable performance as part of a complete measurement system – not just a standalone component.
