Digital Flow Meters and Controllers now protected against dust and water - what that means for you!

Posted by Doug Baker on Thu, Mar 08, 2018 @ 08:39 AM

300 and IP-67.jpgTeledyne Hastings designs and build mass flow controllers for a broad array of markets from clean laboratory environments to heavy industrial installations. Recently, we have been asked to provide our newest line of Digital 300 Flow Meters and Controllers into more demanding environments. And, we are proud to offer an optional IP-67 enclosure, which provides protection against dust and water. More on our product later in the blog.

But first, let’s explore the IP, or Ingress Protection, rating system.  NEMA (National Electrical Manufacturers Association) publishes a standard (ANSI/IEC 60529-2004) entitled, “Degrees of Protection Provided by Enclosures (IP Code)”. The corresponding international standard is IEC 60529. The introduction to the IP Code starts:

 

This standard describes a system for classifying the degrees of protection provided by enclosures of electrical equipment for two conditions: 1) the protection of persons against access to hazardous parts and protection of equipment against the ingress of solid foreign objects and 2) the ingress of water.

 

The IP Code rates the degree of protection by using two numbers. The first number describes protection against solid particles; the second number describes protection against liquids. The Wikipedia page describing the IP Code provides a couple of nice tables to help us quickly understand the numbers.

Dust (First Number) Moisture (Second Number)

IP 0x - No Protection

IP 1x - Objects > 50mm

IP 2x - Objects > 12mm

IP 3x - Objects >2.5mm

IP 4x - Objects > 1mm

IP 5x - Dust Protected

IP 6x - Dust Tight

IP x0- No Protection

IP x1 - Vertically Dripping Water

IP x2 - 15 Degrees Tilt Dripping WAter

IP x3 - Sprayed Water

IP x4 - Splashed Water

IP x5 - Water Jets

IP x6 - Powerful Water Jets

IP 7x - Effects of Immersion

IP x8 - Indefinite Immersion

IP x9 - High Pressure, High Temperature Water Jetting

The second number, “7”, indicates that our instrument can withstand submersion in water up to a meter in depth for up to 30 minutes.

One side note about IP ratings, if you follow the battle between Samsung Galaxy and Apple iPhone, you may have seen an article published by CNET last September (2017). In the article, it was stated that the iPhone 8 and 8 Plus are certified with an IP67 rating, while the Samsung Galaxy S8 is rated IP68. And by the way, yes… according to Reddit, the whole putting the wet iPhone in rice thing to dry it out, does work.  

In order to claim the IP-67 rating, Teledyne Hastings has sent test instruments to NCEE Labs in Lincoln Nebraska. In general, there are two tests, one for dust and one for water. Aaron Steggs, Senior Test Engineer with NCEE explains, “The testing to receive the dust rating is not trivial. There is a vacuum test on the enclosure to ensure that no ingress of dust can occur. The vacuum pressure used is 2kPa.”

Aaron goes on to explain a little about the water test, “When talking about immersion testing, there is a greater chance of water being forced into any opening due to the weight of the water about the instrument under test.”

In any case, we have passed both the dust and water test and now you can have the accuracy and fast response of the Digital 300 Series in an IP rated enclosure.

FAQ Corner – Teledyne Hastings Instruments at Pittcon 2013

Posted by Brandon Hafer on Wed, Mar 13, 2013 @ 03:20 PM

It’s hard to believe that it is now March, which means that Pittcon 2013 is right around the corner. Teledyne Hastings Instruments will have Applications Engineers and representatives in attendance to answer all of your mass flow and vacuum instrumentation questions.

 

PITTCON 2013 LOGOPittcon is an annual conference on laboratory science that is organized by The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. Pittcon started as a small technical conference held in 1950. The first 18 conferences were held in Pittsburgh, Pennsylvania, but the conference has since grown. Locations now vary from year to year with this year’s conference being held at the Pennsylvania Convention Center in Philadelphia, Pennsylvania from March 17-21.

 

There have been many changes over the 60 plus years of the Pittsburgh Conference, and remains a worthwhile event to attend. Teledyne has had a presence at the event for the past 35 years. Included in the weeks events are thousands of exhibitors, numerous technical programs and lectures, and short courses. It provides the opportunity to meet and interact with scientist from across the country and around the world. Papers and articles are presented daily, illustrating the advancements in science in the past year. And finally, it allows for a single location to walk around and see over 17,000 companies and exhibitors with their products and technologies.

Teledyne Technologies Incorporated will have 4 companies in attendance at Pittcon this year. In addition to Teledyne Hastings Instruments, Teledyne Tekmar, Teledyne Leeman Labs, and Teledyne Judson will be exhibiting. Teledyne Tekmar is a leader in the design and manufacturing of analytical instrumentation including products for gas chromatography sample introduction, total organic carbon (TOC) and total nitrogen (TN) analyzers. Teledyne Leeman Labs is a producer of world-class instruments for elemental analysis including ICP spectrometers, atomic absorption spectrometers and mercury analyzers. Teledyne Judson is a leading designer and manufacturer of high performance infrared detectors and accessory products. The Teledyne family of companies will be located in booths 916 and 917, which are located near Entrance D to the Pennsylvania Convention Center. Teledyne employees will be giving presentations on a variety of topics while at Pittcon. If you would like more information on the schedule or the topics to be covered please contact us or stop by our booth and we can provide that information.

Teledyne Hastings Instruments has a great deal of experience with the analytical instrumentation industry. We are always interested in new applications even if they do not exactly fit into the standard product design for mass flow or vacuum instrumentation. We are very willing to examine possible custom designs to meet the requirements of your system. Some examples of previous custom applications include a variety of non-standard packages for both our mass flow and vacuum products, modified electronics, high pressure designs, and even custom designed flow and vacuum sensors.

 

We welcome your comments and your questions and look forward to seeing you at Pittcon 2013. Please stop by our booth and discuss your projects with either Vikki Jewel or Brandon Hafer. You can also email your questions to Victoria.Jewell@Teledyne.com or Brandon.Hafer@Teledyne.comand we’ll be happy to respond and work with you. 

Brandon Hafer is an Application Engineer with Teledyne Hastings Instruments. He was raised in Pottsville in Eastern Pennsylvania and is a fan of the Philadelphia Phillies and Philadelphia Eagles. He is looking forward to returning to the Philadelphia area for Pittcon 2013. If you would like to contact him, he can be reached at brandon.hafer@teledyne.com.
