The Difference Between Ultrasonic and Radar Level Sensors

There is a tendency to pit ultrasonic level sensors and radar level sensors against one another when in reality each sensor has advantages and disadvantages that give each sensor its own place. In this blog, we will look at the differences in how these two technologies work and will cover the applications each sensor is best suited for.

The APG Float Switch Advantage

The APG Vertical Float Switch Advantage

While APG’s Stainless Steel Float Switches might look like your average float switch at first glance, the truth is they are far from being JUST another float switch. APG’s Stainless Steel Float Switches have unparalleled repeatability in actuation and 100% repeatability of float position. To achieve this, APG’s Stainless Steel Horizontal Float Switches and Vertical Float Switches are expertly engineered, from the electrical components to the stainless steel shell, providing greater accuracy and a longer sensor life span that is simply not found in other float switches on the market.

MPI-E Chemical: Safe, Continuous Level Readings in Hazardous OEM Spaces

Pump skids are great OEM products for MPI-E Chemical level probesFor an OEM, level measurement in easy places is, well, easy. In fact, in some places, it’s so easy a float switch can do it (well, several hundred float switches). But we’re not here to talk about those places today. We’re going to look at continuous level measurement with harsh chemicals. And in explosive atmospheres. And the availability to meet OEM and system-integrator needs. That’s right, we looking at the Intrinsically Safe, Chemically Resistant MPI-E Chemical Float Level Transmitter.

How to Configure Your Float Switch: Normally Open Switches vs Normally Closed Switches

normally open vs normally closedDeciding whether your float switch needs to be normally open or normally closed for pump control can be a little confusing. So we would like to clear things up.

When we say normally open or normally closed, we are referring to an electrical circuit. An open circuit is incomplete, meaning that the electric current is unable to complete the loop due to a gap. A closed circuit is complete with no gaps, enabling the current to travel through the whole loop.
