Types of Thermistors
In a previous blog we discussed what a thermistor is and how it works. We also examined what a resistor is because a thermistor is really just a special type of resistor. Let’s delve a little deeper into what different types of thermistors there are, what they are made from, and what sort of jobs […]
What Types of Sensors are in a Current Transducer?
The way a current transducer works can seem like magic; it can measure a process current without even touching it! If you’re brand new to trying to figure out this incredible process control instrument we’ve talked about the basics of sensing magnetic fields through induction in some previous blogs. Be sure to read our discussion […]
Current Transducer: How does it work?
Electricity is the lifeblood of modern industry; computers, pumps, lights, motors, conveyors, and machinery all require power to run. One would be hard-pressed to name a product that doesn’t require an electrical input somewhere within its manufacturing process. Just like other measurable environment variables, such as pressure, the monitoring or measuring of electrical current can […]
Thermocouple Junction and Type: Basic Guide
Thermocouples are incredibly versatile instruments; they are rugged, dependable, and of simple construction. When it comes to designing a thermocouple, however, there are many choices such as thermocouple junction; thermocouple type. It can be hard to know what options are available and what they do. If you’re still not quite as familiar with this sensor […]
How to Protect a Thermocouple
The construction of a thermocouple is incredibly simple; it’s really just two different metal wires that connect to each other at the two ends. One of those connections, the reference junction, can usually be tucked away in a safe place, far from hostile environments. However, the measurement junction will always be in the thick of […]
What is the Hall Effect?
The 19th century was a time of great scientific leaps. It was back in that era when the Hall effect was first discovered; a way to measure a magnetic field. It may seem like a long time ago and discoveries of that age can seem relatively primordial compared to newer scientific concepts like human genome […]
Thermocouple Wire: A Basic Guide
There are a lot of options when it comes to thermocouple design; we’ve gone through a couple of considerations already in “Guide to Choosing a Thermocouple Junction and Type.” For this blog, we’ll discuss all sorts of aspects related to thermocouple wire. There are hundreds of choices when it comes to picking the right thermocouple […]
What is a Thermowell?
Process control environments can be pretty inhospitable at times; fluids and gases can be corrosive and variables like temperature and pressure can reach extreme valuations. Even a moderately harsh environment can be detrimental to equipment if it is exposed over a long period of time. In these tough working conditions temperature sensors like thermocouples and […]
