When you need to measure a vacuum, you may instantly think of a compound pressure gauge instead of absolute pressure gauges. After all, that’s how they’re used. However, you might want to take a look at absolute pressure gauges. The differences between the two are relatively subtle but essential. So let’s take a look. Reference […]
Many water wells range in depth from 10 to 60 feet, while others are up to 100 feet. So when a customer needs a water level sensor in these deep wells, the experts at Automation Products Group, Inc. (APG) recommend our submersible pressure transducer, the PT-500. Submersible pressure transducers are a favorite in the water […]
You have probably heard the term “pressure transducer” used interchangeably with a few other terms, such as “pressure transmitter” and “pressure sensor.” So what does pressure transducer really mean? How is it different than the other terms so loosely tossed about? Before we go any further, it’s worth pointing out that there are many contextual […]
Accuracy on a water level sensor can be confusing. The specifications tell users the error band as a percentage of a specific scale, rather than directly giving the accuracy. The same principles apply to all level sensors, no matter what’s being measured. At Automation Products Group, Inc. (APG), we’ve put together a guide on how […]
Electromagnetic interference (EMI), also known as electrical noise, can destroy a clean signal from your level sensors and pressure transducers. Protecting your sensors from electrical noise is a top priority. At Automation Products Group, Inc. (APG), we’ve put together four tips to keep EMI at bay. Let’s take a look! Tip 1: Shielded Wire Our […]
Variable frequency drives are important in pump systems. They’re a cost-saving solution in pump control. Some of the sensors we offer at Automation Products Group, Inc. (APG) can work with variable frequency drives. What is a Variable Frequency Drive? A variable frequency drive (VFD) is a power supply to an AC pump motor. Its job […]
Independent testing laboratories, such as the Canadian Standards Association (CSA) and Underwriters Laboratories (UL), serve as a third party to validate and ensure that a product is safe for use. For many years, UL was regarded as the foremost certification laboratory in the United States. Yet, within the past 20 years, acceptance of CSA in […]
Calculating the width of an ultrasonic beam can be a little tricky. Luckily, the experts at Automation Products Group, Inc. (APG) have done it enough times that we can give you a solid reference point. We have to make a key assumption in order to do it: maximum sensitivity settings. If your ultrasonic sensor’s sensitivity […]
Calibration is a critical aspect of pressure sensors, and that includes submersible pressure sensors. Regular calibration of your sensor will help maintain accurate pressure measurements and reduce the risk of the calibration shifting. At Automation Products Group, Inc. (APG), we offer the PT-500 Submersible Pressure Transducer, the only pressure sensor on the market that can […]
