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.

In a fast-paced industrial world, precision and accuracy are more critical than ever. Choosing the ideal force gauge is the ultimate key to securing reliable and stable results, whether for quality assurance or material strength testing. But here's the challenge: with so many options out there, how do you pick the right digital force gauge for your specific needs? To streamline this technical evaluation process, ATO Industrial Automation delivers the expert guidance you need to maintain a competitive and highly productive edge in today’s demanding market.

Angle sensors are devices that convert rotational movement into electrical signals for accurate position feedback and control. They use different sensing principles such as magnetic, optical, capacitive, or resistive, and are available in contact, non-contact, absolute, and incremental types. Widely applied in industrial automation, robotics, automotive, and energy systems, their selection depends on accuracy, range, output type, and environmental requirements.

A hydraulic electric pump is a motor-driven hydraulic unit that converts electrical energy into hydraulic pressure to power cylinders and hydraulic motors. To ensure you make the right choice and avoid operational pitfalls, this guide covers its selection techniques, configurations, and troubleshooting solutions.

Buy the right hipot tester to ensure not only safety for end users but also compliance with international and local standards. Hipot testing is a critical process for ensuring electrical safety and equipment reliability. Whether you are testing industrial machinery, electronic devices, or printing equipment, a proper Hipot Tester protects both your products and users. ATO Online Store presents a comprehensive guide to help you pick the perfect hipot tester.

Choose the right shore hardness tester based on your material. Soft foam needs a shore 00 or shore o tester. Medium rubber and leather require a Shore A hardness tester, also called a rubber hardness tester. Hard rubber and rigid plastics demand a shore D or digital shore D hardness tester. This guide includes a product table covering eight scales from Shore 00 to Shore D, a pre‑purchase checklist, and five FAQs, including how to choose between a Shore C hardness tester and a Shore D hardness tester. Whether you need a portable hardness tester for fieldwork or a digital shore hardness tester for the lab, this guide helps you make the right choice.

Proximity sensor is a general term for sensors that replace the contact detection methods such as limit switches and aim to detect without touching the detection object. The movement information and presence information of objects can be detected and converted into electrical signals.

As proximity sensor is so important, today we are going to introduce two types of proximity sensor. We hope that you can know the specialties of two types of proximity sensor.

Struggling with ground loops or 4-20mA noise in PLC/DCS systems? Learn how to choose the right industrial signal isolator and conditioner to protect your panel. If you are confused by terms like ground loop, common mode interference, or different signal types such as 4-20mA and 0-10V, you are not alone.

For example, in a factory with variable frequency drives (VFDs), electrical noise can easily distort sensor signals and cause unstable readings. In chemical plants or oil facilities, improper grounding can even damage PLC input modules due to ground loops.

That’s where signal isolators become essential—they stabilize signals, protect equipment, and ensure accurate data transmission.

A micrometer is a highly accurate measuring tool used to measure the dimensions of an object. The micrometer derives its name from the fact that its measurement accuracy is usually measured in thousandths of an inch or thousandths of a millimetre. It is a common tool used in machine building, engineering, manufacturing and quality control to measure the precise dimensions of small objects. ATO Industrial Automation has organised the prices of all micrometers on sale for you so that you can choose the one you want more quickly.

A fiber optic sensor uses optical fibers to detect objects, position, pressure, or changes in the environment by transmitting light signals. It is widely used in industrial automation where high precision and stable sensing are required. Here is a professional fiber optic sensor selection guide from ATO Online Shop to assist you in choosing the right model.

Confused about when to use a force sensor versus a pressure sensor? These two devices are often mixed up, but they serve very different purposes. In this article, you will learn their core differences: force sensors measure total force (like weight or clamping force), while pressure sensors measure force per unit area (like tire pressure or hydraulic pressure). We explain how each sensor works, why people confuse them, and where they are typically applied. You will also find a practical selection table that covers key environmental factors such as temperature, humidity, electromagnetic interference, and mounting requirements. By the end, you will know exactly which sensor fits your project.

ATO.com explains in detail the methods and procedures for calibrating dew point sensors, including two-point calibration, single-point calibration, chilled mirror method, field calibration, and error adjustment techniques, to improve measurement accuracy for industrial and compressed air systems.

One of the most surprising misconceptions in industrial monitoring is using "dew point" and "humidity" interchangeably. While they seem similar, they are fundamentally different metrics measured by a Dew Point Sensor and a Temperature & Humidity Sensor respectively. Understanding these differences is critical to preventing hidden moisture damage and ensuring production safety.

An air quality sensor is an electronic device used to monitor the concentration of pollutants (such as PM2.5, CO2, VOCs, etc.) and environmental parameters such as temperature and humidity in real time. It is widely used in fields such as environmental monitoring, smart homes, and industrial emission control, and can provide data support for air quality assessment and health protection.

Potential transformers are key components in power systems, used to measure voltage signals and ensure the safe operation of the power system. Purchasing a voltage transformer is an important decision as it will directly impact the performance and reliability of your power system. The ATO store potential transformer buying guide will provide you with detailed information on how to select, evaluate, and purchase voltage transformers to ensure you choose the most appropriate product to meet your needs. Choosing a suitable voltage transformer is very important, as a wrong choice can lead to skewed measurement results or endanger personnel safety. Here are some of the main factors to consider when purchasing a potential transformer.

A current transformer (CT) is a fundamental device used in power systems and industrial automation for measurement, protection, and control. Current transformer polarity defines the directional relationship between the primary and secondary currents. If the polarity is incorrect, it can lead to reversed measurements, inaccurate fault current calculations, and even malfunction of protection systems such as relay misoperation or failure to trip. Because of this, verifying current transformer polarity is a critical step during installation and commissioning. In the following sections, we will introduce two reliable methods to test current transformer polarity: a simple DC method for quick field verification and a professional tester approach for more accurate and efficient testing.
