Mastering High-Temp Measurement: A Guide to Platinum-Rhodium Thermocouple Troubleshooting Apr 14, 2026

Published: April 14, 2026 Category: Process Instrumentation & Sensors Platinum-Rhodium (Pt-Rh) thermocouples remain the gold standard for high-temperature measurement. Known for their exceptional stability and oxidation resistance in inert or oxidizing atmospheres, these sensors can handle sustained temperatures of 1600°C and intermittent peaks up to 1800°C. However, precision comes with its own set of operational challenges. In today’s post, we address the most common field issues regarding fault diagnosis and signal interference. I. Diagnostic Protocols: How to Identify Input Failures When your controller or DCS isn't giving you the readings you expect, follow these three logic steps to isolate the fault: 1. The Polarity Check If the device is powered o...

How to Select the Right Pressure Gauge: Key Parameters to Consider Mar 20, 2026

A pressure gauge, commonly referred to as a spring tube pressure gauge or analog pressure gauge, consists of a measuring system made up of a connection, a spring tube, and a transmission mechanism. When the measured pressure changes, the free end of the spring tube moves, and the corresponding pressure value is indicated on the dial. The pointer shows the pressure reading by pointing to the corresponding scale. Pressure gauges are typically used to measure the working pressure of liquids, steam, gas, or other media in closed systems. When selecting a pressure gauge, it is important to take into account various factors such as the application environment, readability, medium characteristics, and installation method. Below are the key parameters to consider: 1. Measuring Medium &ndas...
