Proper load resistance is important in DC control and communication circuits. Control networks need it to function, and it determines how power is flows within a circuit. Here at Automation Products Group, Inc. (APG), we’ll define load resistance, what it’s for, and how a control network fits into it. Load Resistance Defined At the most […]
With wiring and connections, several problems can prevent a sensor from reading properly. At Automation Products Group, Inc. (APG), we’ve seen many issues with wiring. This is why we’ve put together this guide on the five most commonly identified wiring problems and their solutions. Problem 1: Vibration and Loose Wiring Vibration is common throughout industry. […]
A multimeter is crucial for troubleshooting an industrial sensor. We’ve asked the experts here at Automation Products Group, Inc. (APG) to provide a guide on how to use a multimeter to troubleshoot your industrial sensor and get it working properly in no time! What is a Multimeter? A multimeter is an electrical instrument used to […]
Controlling pumps with standard cable-suspended float switch can be challenging. You need at least two float switches and a controller to manage the logic. Securing them to conduit to prevent tangling is necessary, and their reliability is often limited, with an expected lifespan of only two to three years. Why Choose the Kari Float Switch […]
When deciding how far you can run conduit and cable, keep a few things in mind. The power supply and the communication signal should be considered. Resistance, electrical noise, and the output signal limit the length of your cable runs. At Automation Products Group, Inc. (APG), we’ve consulted with our team of experts and put […]
A power supply, whether regulated or unregulated, is vital in electronic devices. Most of the world relies on having a power supply. Understanding the differences between a regulated or unregulated power supply can assist you in choosing a sensor from Automation Products Group, Inc. (APG), and we’ve put together a handy guide to get you […]
Float level transmitters rely on matching the right float with the right specific gravity, or density, of your liquid. While there are other specifications that matter (i.e. chemical compatibility, temperature, and pressure), the accuracy of your float level transmitter is tied directly to specific gravity. Each float has a reference point where the float is […]
Shunt Cal, short for Shunt Calibration, is a method for determining the full-scale output of a pressure transducer by electrically simulating a full-scale load. Either a shunt resistor is applied to the transducer circuit, or voltage is applied to an ancillary circuit designed to generate a full-scale output. That output can then be measured precisely […]
Two of the most well known protection methods for instrumentation in hazardous areas are Intrinsic Safety and Explosion Proof. The difference between the two is quite large, and amounts to the idea of prevention vs containment. Then there are the practical differences, which are largely based on how the two are wired. We’ll discuss these […]
