Behind the Scenes: Creating a Custom Thermistor Probe

Recently, we put out a press release Customization Capabilities for NTC Thermistor Probe Assemblies announcing our ability to create customized NTC thermistor probe assemblies to fit the specific needs of any application. In today’s blog post, we are going to give you a behind the scenes look at one of our custom designs.

Let’s get started!

More than two years ago the team at Ametherm began working on a custom probe to measure gas flow in a pipe. The velocity of gas causes temperature to change. An NTC thermistor exhibits a change in resistance, which correlates to different velocities of the gas. For this particular project, our client needed a modified housing to handle 100 psi of pressure.

To begin the project, our engineer worked closely with a sales representative who was local to the area of our client. This ensures that we get the highest quality information and first-hand knowledge before we get to work. At this stage close communication happens back and forth via phone and email to confirm part numbers, price quotes, timelines and all the details needed to create the sample.

Here you can see the customized NTC thermistor probe sample sitting next to the original drawing drafted by one of our engineers. Each project starts on paper before the creation process begins. This ensures that your vision gets perfectly executed to fit the individual needs for each application.

After understanding the application, Ametherm had to build a fixture so that each part can be tested at 300 psi prior to shipment to the customer.

Pictured here is a custom gas pipe built by Ametherm. It was used to test the NTC thermistor before sending the sample off to the client. This allows us to address any issues or problems before it reaches our customer’s hands. Quality is our number one priority when building custom probes.

As a result, Ametherm became the only vendor that was able to satisfy the customers need in the most effective manner. While many companies manufacture and sell NTC thermistors, our customers have an advantage due to our dedication to provide both quality products and excellent service.

“We can customize our probe assemblies in any way the customer wants — including matching or creating any resistance temperature curve — and we offer the highest isolation voltage available,” says Eric Rauch, president and CEO of Ametherm.

In an age of digital communication, many companies simply do not have the time and resources to address each customer individually. However, at Ametherm we take projects on for the long-haul and work one-on-one with you to find the perfect solution. In short—we’re problem solvers, we’re dreamers, and we’re here to help.

As always, thanks for reading!
