Let’s Chat About Air Pressure Switches!

Janis Rozenbergs — Tue, 18 Jun 2019 18:28:27 +0000

Air flow pressure switches and differential pressure switches work just like the light switches we have in our living rooms at home: when they are switched on, the switch makes contact, closes the circuit, and turns on. When they are switched off, the circuit is broken and power turns off. With air flow switches, instead …

Analog vs. Digital Device Signals

Janis Rozenbergs — Thu, 28 Mar 2019 15:57:33 +0000

In today’s industry, the number of device output signals continues to grow. Each signal is different; so how do you figure out which one is right for your application? The easiest way to hone-in on the correct signals for your application is to decide whether you want a digital communication signal or an analog signal. Most …

Select Key Pressure Measurements and Their Importance

Janis Rozenbergs — Wed, 28 Nov 2018 13:56:13 +0000

Last September, we wrote about the different types of pressure and how each type is referenced. This post discussed atmospheric (barometric), absolute, gage, vacuum, differential, and hydrostatic pressure. For a refresher on these pressure types, click here. This post will expand on last September’s post by listing some more key pressure measurements and explaining their …

Pressure Monitoring in Pump Systems

Janis Rozenbergs — Wed, 14 Nov 2018 14:35:17 +0000

Why do the inlet and outlet pressure of pumps need to be monitored? What issues may be encountered if they are not monitored? Air compressors, irrigation systems, and heat exchangers all use pumps to push air or water through their systems. If the pressure in any of these systems is too high or too low, …
