Your System Has Powered Up – But Does It Know Where It Is? Absolute Position Sensors vs. Homing

What happens after a power interruption if your system no longer knows where the mechanism actually is? In many motion control applications, an incremental encoder requires a homing sequence before normal operation can resume. This article explains how Absolute Position Sensors eliminate that dependency, enabling faster startup, reducing system complexity, and providing immediate position feedback after power-up.

Why a Linear Position Sensor Shouldn’t Be Selected by Stroke Alone

Most engineers start by asking, “What stroke do I need?” In reality, that’s only the beginning. Choosing the right linear position sensor requires far more than matching the measurement range. This article explains why operating conditions, mechanical design, installation constraints and expected service life often have a greater impact than stroke alone – and how to choose the right sensor family for your application.

Does Your Thermal Protector Really Solve the Problem? Or Just Give the System Another Chance to Fail?

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.

Your Temperature Sensor Says 80°C. The Real Hot Spot Could Already Be at 130°C

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.

How Differential Pressure (ΔP) Can Reveal Problems Long Before a System Shuts Down

,

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.

Choosing the Right Temperature Probe Mounting

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.

From 5kW to 100kW Racks – The Engineering Challenges Behind Modern AI Data Centers

, ,

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.

Contactless Rotary Position Sensors – Why More and More Systems Are Moving to Non-Contact Sensing

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.

Choosing the Right Linear Position Sensor: Why Stroke Length Is Only the Beginning

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.
