The most-read articles in June 2017

June is coming to an end. That means it’s time for our monthly recap of popular articles posted on Visaya! This month we focused on pH sensors and multi-parameter analytical transmitters. We reviewed a handful of devices and even created a list of relevant players on the market. We also wrote our first definitive guide, where we put together all you need to know about pressure transmitters, from basic principles to possible applications.

If you missed any action this month, you can catch up with this recap! Or even better, you can subscribe to our weekly newsletter and never again miss a piece of quality content. As a bonus, our newsletter brings you some of our shenanigans in Berlin and cartoons with engineering jokes. If I were you, I wouldn’t miss out!

Oh, almost forgot. This month was also the Harry Potter 20th Anniversary! We prepared a geeky meme for y’all:

Enough talk! Let’s move to the most-read articles of June!

1. How to scale out a new pH sensor

Let’s hop in the pH pool and talk about pH sensors on the market. A pH sensor receives a millivolt signal from an electrode and converts it into a pH value. Your solution temperature can factor in here for the measurement and the electrode. Read more

2. The definitive guide to pressure transmitters

Today, you’ll learn all the things about pressure transmitters! We put together some of our best content into a handy guide that either a beginner or an experienced engineer can use. Read more

3. Comparison: Liquiline M CM42 vs KNICK Stratos Pro

Here at Visaya we strive to simplify, offering clear and easy explanations about various topics. Today, we have our second analytical transmitter comparison, and we brought two big players in this market! Read more

4. Common errors with pH sensors

Once upon a time, I had to troubleshoot a pH measurement in a wastewater plant. I knew the technicians had properly installed the loop, consisting of pH electrode, cable, and transmitter. But they asked me to find out why the plant manager called the measurements “time dependent.” Read more

5. How to calibrate a pH sensor

Let’s do some calibration! I know, but you must adjust/calibrate your pH sensor sooner or later. If you need those measurements, then you need this calibration. It’s not so bad, but it is necessary. Let’s first sort out what calibration and adjustment mean. Read more

6. Analytical sensors – Why switch from analog to digital?

Let’s park pH for a minute and learn a bit more about digital analytical sensors. The industry clearly favors the digital sensor trend, as they’ve become more common over the past decade. But why?

Vendors say reliability and ease of use. But does this argument cover the markup on these things? If not, then what else do they offer? Read more

7. Gas scrubbers, pH measurement, and you

Let’s talk about acid rain and what we do about it. Yes, it still exists, but modern manufacturing practices have made it much rarer. 

It mostly comes from gases emitted as a byproduct of burning coal or oil-based fuel, which leads to a high load of sulfur dioxide (SO2) compounds. Read more

8. 6 pH transmitters you must know

We reviewed a couple of pH transmitters that you’ll see again in a moment, and we wanted to add other options for you to consider as well. But I have a question before we get started. Does your accuracy depend on your transmitter? What do you think? Read more

9. Can you share lemonade digitally? The awesome future of the digital twin

Today if you want to get a lemonade you are better off going to the lemonade stand. Nevertheless, the concept that will allow us to someday have a digital glass of lemonade is being implemented today within the realm of IoT. Read more

10. The Awesome Origin of the pH Scale

Some days ago I went for a stroll in Berlin with a strange-looking device. I asked people what they thought it would do.

What I had was a pH electrode, one of the best tools we have to determine if a solution is acid or alkaline. But let’s take a step back and define pH and its meaning.  Read more
