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.

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.

Buying appropriate fiber optic sensors is crucial to ensuring optimal performance and reliability in various applications. The correct choice enhances system efficiency, reduces maintenance costs, and ensures long-term durability. To assist you in making the right choice, ATO Online Shop has created an in-depth guide on selecting the ideal fiber optic sensors.

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.

In industrial automation, a "clean" signal is the difference between a smooth-running factory and a maintenance nightmare. If you’ve ever seen a PLC reading jump around for no reason, you’ve likely encountered signal interference. To fix this, we use two main tools: Signal Isolators and Signal Conditioners. While they look similar, they do very different jobs. Let’s break it down.

A float switch is an automatic liquid level control device used to start or stop pumps based on liquid level changes in tanks or industrial systems.In chemical tanks, float switch failure is a serious issue that can lead to overflow, dry-run pump damage, or production shutdown.The most common causes of failure are chemical corrosion, electrical overload, and buoyancy instability.In harsh environments, standard float switches often fail due to cable hardening, material degradation, or chemical attack. This guide explains how to diagnose these issues and choose a reliable industrial-grade float switch.

An hour meter is a device used to record the total operating time of equipment, helping you schedule maintenance, prevent overuse, and extend equipment lifespan. Choosing the right hour meter is essential and depends on your application. This guide will help you quickly compare different types and select the best option for your needs.

A current transformer (CT) is a fundamental device used in power systems and industrial automation for measurement, protection, and control. CT 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 CT polarity is a critical step during installation and commissioning. In the following sections, we will introduce two reliable methods to test CT polarity: a simple DC method for quick field verification and a professional tester approach for more accurate and efficient testing.
