Not all liquids are created equal. The level of some contained liquids is easy to detect, while other liquids create a heavy foam or vapors that can cause problems for ultrasonic level sensors. Problematic Foam and Vapors Ultrasonic level sensors use sound waves to measure the level of the liquid. Heavy foam can absorb the […]
Many liquids used in processing applications will separate from each other when allowed to settle. They do this either because they’re completely immiscible, or they have different densities. When a liquid level of each is required, you need a dual level sensor, also known as an interface level sensor. At Automation Products Group, Inc. (APG), […]
Proper mounting is critical for an ultrasonic sensor. Mounting mistakes are one of the most common installation pitfalls with ultrasonics. We’ve consulted with our experts at Automation Product Group, Inc. (APG) to create this handy guide on installing ultrasonic level sensors. Here are a few practical guidelines that can help ensure trouble free installation for […]
Ultrasonic level sensors are a little farsighted. By nature of the technology, most don’t measure surfaces within a few inches of the transducer face. This is known as a blanking distance. Understanding this blanking distance is the key to understanding how your ultrasonic level sensor measures distance. At Automation Products Group, Inc. (APG), we’ll further […]
Industrial areas that present a risk of fire or explosion are called hazardous locations. Sensors installed in these areas can potentially ignite flammable vapors, dust, or fibers. To prevent a disaster, these sensors must be designed in a way that eliminates risk. At Automation Products Group, Inc. (APG), we provide specialized sensor that are safe […]
Your Guide to Level Measurement with Pressure Sensors When it comes to measuring liquid levels, pressure sensors are up for the task. Here at Automation Products Group, Inc. (APG), we offer several pressure sensors that can tackle liquid level measurement with ease. Pressure transducers measure level by detecting the pressure exerted by the volume of […]
Both NEMA enclosure types and IP ratings types provide protection for electrical components. However, the two different systems vary in the terminology used and the types of protection offered. The conversion chart our experts at Automation Products Group, Inc. (APG) put together below illustrates this. Review of IP Ratings An IP rating is specified by […]
With hazardous locations, CSA standards are a must for safety. At Automation Products Group, Inc. (APG), we offer multiple products that adhere to CSA standards. But what are CSA standards and why should you use them in your operations? Read on to learn more. What is CSA? CSA stands for the Canadian Standards Association, but […]
