Transmitter TEST terminals play a crucial role in the calibration, maintenance, and troubleshooting of various industrial and laboratory equipment. These terminals are often overlooked but are essential for ensuring accurate and reliable performance. Understanding their function and the different ways they can be utilized is key for effective use and system optimization. 1. Purpose of […]

Introduction In the process of maintaining field instruments, a common issue is the transmitter cover being stuck or unable to open. This document outlines common causes and corresponding solutions in a structured and actionable way. 1. Bolt or Screw Issues 1.1 Rust or Corrosion Cause:Prolonged exposure to moisture or corrosive environments can lead to rusted

Transmitters such as pressure, differential pressure, and level transmitters are vulnerable to moisture ingress in humid environments (e.g., outdoor installations, damp workshops, underground pits, wastewater treatment plants). Water vapor can penetrate the housing, terminal compartments, or sensor diaphragms, leading to short circuits, signal drift, distorted outputs, or even total failure. To ensure reliable operation, a

Noise in transmitters can significantly affect the accuracy and reliability of measurements in industrial and electronic systems. Understanding the different types of noise that can occur within a transmitter helps in designing systems that minimize these disturbances, ensuring more stable performance. Below is a detailed breakdown of the common types of noise found in transmitters,

Power cycling, or turning a device off and then on again, is a common troubleshooting technique that can resolve many transmitter issues. This article explores the technical principles and reasons behind its effectiveness, supplemented with real-world examples and practical advice. Resetting Internal Components Transmitters rely on numerous internal components, such as microprocessors, memory chips, and

In modern manufacturing environments, particularly within the scope of Industry 4.0, smart transmitters are crucial for achieving higher levels of automation. These devices provide real-time monitoring, diagnostics, and control, making them indispensable for ensuring operational efficiency and system reliability. By incorporating predictive maintenance features, smart transmitters can anticipate potential failures and schedule maintenance activities before

Selecting the right transmitter for an application is a crucial process that ensures accurate measurements, reliable performance, and cost-effectiveness. This article provides a comprehensive guide on transmitter selection, detailing key steps, factors to consider, and common pitfalls to avoid. Step 1: Define Measurement Requirements 1.1 Identify the Measurement Parameter The first step in selecting a

The output range of a current output transmitter is 4–20mA. In a previous article, we explained why the conventional current output range is 4–20mA.  When the current output transmitter produces the minimum and maximum current, it respectively represents the minimum and maximum rated output values calibrated for the current transmitter. Let’s take a current transmitter

Nowadays, people have increasingly higher demands for their living and working environments, and the harmful effects of dust on the human body have become more evident. Industrial dust, coal combustion dust, vehicle exhaust dust, and construction dust are the main sources of urban dust. The progress of urbanization inevitably comes with an increased demand for

In industrial automation and control systems, the output signals from transmitters can generally be categorized into two types: analog signals and digital signals. Over the years, both types have been well-developed and widely adopted. However, digital signals have been increasingly favored by users due to their unique advantages. Advantages of Digital Signal Output 1. Superior
