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...

In the era of Industrial Automation 4.0, the accuracy of process data is the pulse of operational success. At Anhui Tiankang (Group) Shares Co., Ltd., we have refined the art of pressure measurement with our flagship TK3051C Series. These advanced transmitters are engineered to bridge the gap between high-force physical environments and high-intelligence digital control systems.   1. Advanced Technology: Monocrystalline Silicon Sensing The TK3051C series leverages cutting-edge monocrystalline silicon sensor technology to deliver unparalleled precision. Capacitive Principle: Measured media acts upon high and low-pressure isolation diaphragms. This pressure is transferred via filling fluid to a central measuring diaphragm. Capacitance to Signal: Displacement of the measuring diaphragm&...

  In the complex landscape of process industries—ranging from petrochemical refining to pharmaceutical manufacturing—the pressure gauge is more than a simple indicator; it is the "first line of defense" for operational safety and efficiency. As an instrument engineer, I understand that selecting the right gauge requires a deep dive into media characteristics, environmental factors, and precision requirements. Below is a technical breakdown of the Anhui Tiankang (Group) Shares Co., Ltd. pressure gauge portfolio, designed to help international procurement and engineering teams make informed decisions. 1. Understanding the Core Technology: Bourdon Tube vs. Diaphragm The heart of a pressure gauge is its sensing element. Choosing the wrong one can lead to premature fatigue or c...

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...

Thermocouples have become indispensable tools in modern industrial environments where accurate, stable, and real-time temperature measurement is essential. Among all thermocouple categories, Type K stands out as the most widely used and most versatile temperature sensor across industries. Its broad temperature range, durability, and cost-effectiveness make it a preferred option for engineers, maintenance teams, and equipment manufacturers.   1. What Is a Type K Thermocouple?   A Type K thermocouple is a temperature-sensing device composed of two dissimilar metals—Chromel (Ni-Cr) and Alumel (Ni-Al)—joined at one end to form a measuring junction. When this junction experiences temperature changes, it generates a voltage proportional to temperature, allowing accurate m...
