Inductive and capacitive proximity sensors are two widely used non-contact detection devices in industrial automation systems. Although they look similar, they work based on completely different sensing principles and are designed for different detection requirements. Understanding the differences between these two proximity sensors helps you select the right sensor for specific industrial applications. If you’ve ever found yourself wondering which one to choose for your application, this article will clear up the confusion.

Dual emergency stop is one of the important safety functions of servo motion control systems. It provides an extra protection layer for PLC-based servo motion systems, enabling emergency shutdown from two independent positions. Integrating hardware and PLC software emergency stop circuits to build two independent cut-off paths is a reliable solution. This article explains the full implementation workflow to improve machine safety and minimize equipment downtime.

Industrial communication protocols are the foundation of every modern automation system. PLCs rarely operate alone—they continuously communicate with HMIs, sensors, servo drives, robots, industrial PCs, and other field devices. Communication protocols define how these devices exchange data accurately, efficiently, and reliably.

In a servo positioning system, reliable motion control requires more than simply driving a motor. The system must also be able to detect over-travel conditions, stop motion before mechanical damage occurs, and provide a safe method for clearing alarms after faults are resolved.

This guide demonstrates how to upgrade a PLC pulse-controlled servo system by adding overtravel protection and alarm reset functionality using three interposing relays. The result is a safer and more robust servo position control system suitable for industrial applications.

If you're installing an gas detector controller, this guide explains how to complete both the 3-wire 4-20mA analog output wiring and the 4-wire RS485 communication wiring. Whether you're connecting a single gas detector or integrating multiple detectors into a monitoring system, following the correct wiring procedure is essential for reliable operation and accurate gas monitoring.

A gas detector controller serves as the central management unit of a fixed gas detection system, allowing users to configure connected gas detectors, manage alarms, record historical data, and monitor gas concentrations in real time. This guide introduces the basic operation of the ATO gas detector controller, including menu navigation, 4-20mA output configuration, and historical data export. By following these procedures, users can quickly configure the controller, ensure reliable gas monitoring, and simplify routine maintenance.

Reliable gas detection is essential when working in environments where hazardous gases may be present. The ATO 4-in-1 multi-gas detector is designed to simultaneously monitor carbon monoxide (CO), oxygen (O₂), hydrogen sulfide (H₂S), and combustible gases (%LEL), helping users quickly identify dangerous atmospheric conditions and improve workplace safety.

This guide explains how to operate the gas detector, including powering on, accessing the menu, performing calibration, configuring alarm settings, managing data logging, exporting recorded data, switching measurement units, restoring factory settings, and viewing system information.

In modern automation, high-power Brushless DC (BLDC) motors are increasingly replacing traditional induction motors due to their superior efficiency and compact power density. However, integrating these systems—specifically the 3800W BLDC + Right Angle Gearbox configuration—requires careful attention to control logic, thermal management, and safety protocols.

Optical fiber communication technology has developed rapidly in the last 20 years. Since optical fiber communication transmits a large amount of information at a fast speed, and it can transmits digital signals, which makes it possible to transmit information such as broadband image signals and computer networking. Thus, optical fiber measurement has entered into a new period of digitization.

This blog will guide you through the most important considerations, from required power and control systems to smart home integration and safety features. Keep reading, and ATO Industrial Automation will provide a detailed introduction on how to select the most suitable door opening system for your property.

A lobe pump (or rotary lobe pump) is widely utilized across a variety of industries, including pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. They are characterised by their ability to pump viscous, solids-laden, and sensitive media evenly and without pulsation.

Float switches fail in chemical tanks mainly due to corrosion, scaling, and seal degradation. Choosing a chemically compatible material — PTFE or PVDF for corrosive media — and specifying IP67 or higher ingress protection significantly reduces failure risk. Regular inspection and cleaning prevent the remaining causes.

A portable exhaust fan is a movable ventilation device designed to remove heat, smoke, fumes, moisture, dust, and odors from enclosed spaces. Selecting the correct ventilation system can improve comfort, workplace safety, and long-term operational efficiency. To help you select the right portable exhaust fan more efficiently, ATO Industrial Automation Company provides a professional selection guide.

A 380V sliding vane pump in the 2–10 HP range costs $4,205–$7,942. Each HP tier adds approximately $900–$1,100, driven by motor frame size, body material, and flow capacity.

A floor blower is a high-velocity mechanical fan designed to accelerate the evaporation of moisture from floors, carpets, and structural surfaces by generating a powerful, targeted stream of air close to the ground. Selecting high-quality floor blowers—often referred to as commercial air movers—is critical for ensuring operational efficiency, structural preservation, and safety in both restoration and facility maintenance environments. To make your purchase easier, the ATO online store provides a floor blower selection guide.

A CNC spindle motor is the core drive of a CNC machine, converting electrical energy into high-speed rotation for cutting, drilling, milling, and engraving. It combines mechanical, electrical, and thermal systems to ensure stable speed, torque, and continuous operation. Widely used in woodworking, metalworking, advertising, and mold industries, it typically ranges from 800W to 7.5kW and works with air- or water-cooling and VFD control. Proper selection improves machining efficiency, tool life, and product quality.

Noise pollution is gaining increasing attention in our daily lives, whether at home, in the workplace, or in public spaces. Choosing the right noise sensor is crucial. Identify your primary use case—such as workplace compliance, vacation rental monitoring, or environmental noise studies—then prioritize key specifications like accuracy class, measurement range, and frequency weighting.

A signal isolator electrically separates input and output circuits to block ground loops and interference — the signal type and range remain unchanged at the output.

A signal conditioner converts raw sensor signals (thermocouple, RTD, 0–5V) into standard formats a PLC or DCS can read directly, with amplification, filtering, and linearization built in.

They are not interchangeable. Use the wrong one and you either fail to fix the noise problem or fail to convert the signal.

A Differential Pressure Sensor (DP sensor) measures the pressure difference (ΔP) between two points and converts it into a standard 4–20mA or digital signal for PLC and DCS systems.

In real plant work, engineers often search for issues like “why is my DP sensor reading drifting,” “DP reading fluctuation causes,” or “impulse line blockage troubleshooting.” In most cases, the problem is not the transmitter itself, but installation conditions, impulse lines, or process instability.

This guide combines real industrial experience with core technical principles to help you understand, diagnose, and select DP sensors more effectively.
