The FS-500 is the Only All-Purpose Horizontal Float Switch You Need

The FS-500 is a great fit for food prep and storage applicationsA couple of weeks ago we released our new, side-mount, stainless steel float switches, the FS-500s. They are designed and built here at our facility in Logan, Utah for long-lasting dependability in tough environments. And because you, our customers, use float switches in a wide variety of places to monitor many different liquids, we designed the FS-500 to be tough enough and versatile enough to be the only go-anywhere, use-everywhere horizontal float switch you need.

APG Introduces New Series PT-405 Explosion Proof, Heavy Duty Pressure Transducer

APG's New PT-405 Explosion Proof Pressure Transducer

LOGAN, UT – Automation Products Group, Inc. (APG) introduces the new Series PT-405 Explosion Proof, Heavy Duty Pressure Transducer.

The PT-405 offers unbeatable performance in harsh conditions and hazardous locations. The PT-405 carries a Class I, Division 1, Explosion Proof rating from CSA, an IP65 rated case, and single seal construction for the highest safety factor. With ranges up to 30,000 psi, and outputs including 4-20 mA, 0-5 or 0-10 VDC, and RS-485/Modbus RTU, the PT-405 is as versatile as it is tough.

Prevent Dangerous Benzene Exposure During Flowback Operations

Frack and flowback tankIn a recent cooperation between NIOSH, the government agency for researching work-related injury and illness, and private partners in drilling and well servicing found that workers involved in flowback operations where exposed to elevated levels of benzene, a known carcinogen.

The preliminary results of their study were published on the CDC blog last month. The study was conducted by taking urine samples of workers at the end of their shift. The study also included, “short-term and full-shift personal breathing zone and area air sampling for exposures to benzene and other hydrocarbons.”

How To Wire Intrinsically Safe & Non-Incendive Sensors

Oil & Gas refinery at nightLevel and pressure sensors for hazardous areas are designed in a number of ways to prevent ignition of an explosive mixture. Two of the more popular methods for low-power instrumentation are intrinsically safe and non-incendive.

Both limit power significantly, ensuring there is never enough energy to produce a spark and ignite a dangerous gas or dust mixture. In fact, there is more that is the same between the two protection methods than there is different. So, to help you know when & where they’re appropriate, we will focus on the differences.

How Hazardous Areas Work

hazardous area classification guides us in preventing disasterEver wondered how big your hazardous zone really is? What determines its size? How far away do you have to put sensors or control boxes that don’t have the appropriate certifications?

We’re going to pull back the curtain and show you how hazardous locations really work. It all starts with a fundamental understanding of fire and explosion hazards.

The primary factors in a fire or explosion are fuel, oxygen, and a heat source (ignition). Remove any of these and you’ll prevent or stop the fire. There are secondary factors for...

What Is The Difference Between Explosion Proof And Intrinsically Safe Sensors?

hazardous locations are common in industryPutting electrical equipment in a hazardous location is a big deal. Choosing the wrong sensor turns from expensive to life threatening. So how do you select the right level sensor or pressure transmitter?

You have to understand hazardous locations.

Sensor Design

This is even difficult for many who deal with hazardous locations on a day-to-day basis. If you’re ever confused...

Explosion Proof Protection Method for Hazardous Locations

M1 military helmet has been used to contain explosions from hand-grenadesWe’ve spent some time in the last two weeks discussing hazardous locations and the intrinsic safety protection method. Check out those posts if you’d like to catch up on the subject material. In today’s post, we’ll cover the explosion proof protection method, and how it keeps a hazardous location from ending up in a ball of flames.

Hazardous Location Certifications: The Basics

hazardous locations iconIndustrial areas that present a risk of fire or explosion are called hazardous locations. Sensors that will be 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.

In this post, we will cover the basics of hazardous locations, namely protection methods and hazard types as defined by CSA International, a globally recognized testing and certification organization.

Intrinsic Safety Protection Method for Hazardous Locations

Intrinsic safety barrierLast week we defined hazardous locations, and discussed the basics of both protection methods and hazardous area classifications. This week, I want to discuss intrinsic safety, what it is, and how it prevents igniting a disaster.

James Wilkinson, Automation Specialist at R. Stahl, defines intrinsic safety as the following:

Intrinsic safety can be defined as an explosion protection technique that is applied to electrical equipment and wiring to limit both electrical and thermal energy under both normal and abnormal conditions to levels that are insufficient to ignite the hazardous mixture that is present in the hazardous area.
