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.
