In industrial automation, Programmable Logic Controllers (PLCs) are the backbone of reliable and repeatable control systems. But one common question from engineers and end users alike is: Can a PLC function without an HMI (Human-Machine Interface) or SCADA (Supervisory Control and Data Acquisition) system? The short answer is yes — a PLC can absolutely run […]

Introduction When you apply and remove a load from a weighing system, you’d expect the sensor to return the exact same output, right? But in reality, it often doesn’t. That difference in sensor output between loading and unloading is called hysteresis—and it’s one of the key error sources in load cell performance. This article explores

In industrial environments such as oil, gas, petrochemical, and chemical industries, safety is paramount. Many systems and concepts have been developed to mitigate risks and protect both personnel and infrastructure. Among these systems are SIS (Safety Instrumented System), SIF (Safety Instrumented Function), and SIL (Safety Integrity Level). Other related terms like SILa and SIL0 are
Vortex flow meters are widely adopted across multiple industries due to their rugged design, ability to handle steam and gas, and low maintenance needs. Unlike many other flow meter types, vortex meters can operate effectively under high temperature, high pressure, and challenging flow conditions, making them a popular choice for utility measurement and process control.

In chemical manufacturing, the stable operation of the DCS (Distributed Control System) is a cornerstone of both safety and efficiency. However, a seemingly insignificant issue such as an aging data cable can trigger serious chain reactions — including interlock activation, emergency shutdowns, and potential process disruptions. This case study details how a fault in a
When it comes to flow measurement in industrial systems, two widely used technologies are vortex flow meters and differential pressure (DP) flow meters. Both have proven reliable across industries, especially for steam, gas, and liquid applications. However, they differ significantly in principle, performance, installation requirements, and cost. This article compares vortex vs. differential pressure flow
Introduction When integrating a load cell into your weighing system, one of the most overlooked—but critical—decisions is choosing the correct wiring configuration. You may encounter 2-wire, 3-wire, or 4-wire load cells in specifications or datasheets.So… what’s the difference, and why does it matter? This article explains each wiring type, its pros and cons, and which

In the realm of industrial automation, I/O (Input/Output) modules play a critical role in facilitating communication between the control system and the external devices that it manages. These devices could be sensors, motors, valves, or other hardware components. Without the I/O modules, automation systems would be unable to receive data from the real world or
