Choosing a thermocouple comes down to two questions: what are you measuring, and how hot or cold does it get? This guide covers sensor styles for air, surfaces and liquids, how to pick a junction, and when to use K, J, T or another type.

Buy your thermocouple and get it calibrated in one order. IOThrifty now offers 3-point thermocouple calibration, NIST-traceable or ISO/IEC 17025 accredited, at prices that won't break the budget, with standard or custom calibration points.

How short-wave thermal cameras measure melt pools in laser additive manufacturing, why emissivity matters for hot metal, and where the PI 08M fits.

Two-wire transmitters power themselves and send their signal over the same pair of wires. Learn how the 4-20 mA current loop works, why it became the industry standard, how to wire multiple devices in series, and how to calculate maximum cable length.

For years, great remote monitoring was only built for companies with the biggest budgets. So we built Dasberry Cloud: an easy, truly device agnostic IoT platform with dashboards, data logging, alerts and reporting for any MQTT device. A generous free plan, everything-included pricing, and a free perpetual license with every connected device we sell.

When traditional wired sensors aren’t practical, wireless industrial sensing can bridge the gap without the complexity of a full PLC system. In this article, IOThrifty walks through a real-world application where temperature and humidity had to be monitored on a moving machine using a wireless sensor, Modbus gateway, and relay controller. The result was a simple, self-contained control system with no Wi-Fi, PLC programming, or IT infrastructure required.

Monitoring asphalt temperature at every stage of road paving, from the plant to final compaction, is essential to ensure a durable, long-lasting surface. This article explains how and when to measure temperature using infrared tools, with a special focus on the IOThrifty PyroCouple sensor as a smart solution for construction professionals.

Measuring flow in liquid-cooled data center racks is critical as power densities increase and traditional air cooling falls short. This comprehensive guide explains how coolant flow is monitored in direct-to-chip and rear-door heat exchanger systems, including equations, sensor technology tradeoffs, and BMS integration. It is written for engineers responsible for designing and operating modern, high-density data centers.

A signal conditioner is the critical link between sensors and control systems, transforming raw, noisy signals into clean, standardized data engineers can trust. From amplifying microvolt readings to isolating circuits and linearizing temperature inputs, it ensures accurate and safe measurements in demanding environments. In temperature control applications, devices like the TxRail-USB, TxIsoRail, and I4P from IOThrifty deliver reliable, noise-free 4–20 mA or 0–10 V outputs that keep industrial systems running smoothly.
