Introducing Brett Larsen to the sales team

New Sales Representative

The Morris Technology group would like to take this opportunity to introduce our newest addition to our sales team, Brett Larsen.
Brett has been manufacturing temperature sensors at D&N for over 20 years and is keen to apply his vast technical knowledge to assisting our clients to find the best solution for their temperature requirements.
You can contact Brett on 0249526344 or head over to our contacts page and send him an email.

High Temperature Cable Part 1

Type K Thermocouple WireWhen choosing your high temperature cable care must be taken. There are many types of insulation used with varying degrees of thermal resistance and tensile strength. D&N supply such a wide
range we will be separating this blog into two parts. This article will look at our range of PVC, Polyamide and Teflon high temperature cables, and what applications they are suited too.
When selecting a high temperature cable a few factors must be taken into account.

RTDs In Depth

Resistance Temperature Detectors (RTDs) rely on the predictable and repeatable phenomena of the electrical resistance of metals changing with temperature. The most common metals used for temperature sensing are platinum, nickel and copper.

Carbon Bake Furnace Specialists

A carbon bake furnace (CBF) is a super-sized oven which bakes carbon blocks, called “anodes”. These blocks are required in the aluminium production process.

D&N Engineering has been operating since 1974. During that time, we have worked extensively with Tomago & Hydro Aluminium providing solutions to assist them in improving and maintaining their CBF processes. This is why within the industry we are often referred to as “The Carbon Bake Furnace Specialists”.

Stellite Coated Thermowells

As mentioned in our last blog “choosing your thermowell” a thermowell will keep your temperature device protected. But, in some industrial processes the extreme environments that a standard thermowell is exposed can significantly decrease the thermowells lifespan, and can put your temperature device at risk. For example, in power station processes pulverized coal dust travels at high velocity. This causes the thermowell to erode and if not quickly replaced can expose the temperature device. In this situation you will need to have your thermowell stellite coated.

Choosing your Thermowell

In some cases, not using a thermowell can cause irreversible damage to your temperature sensor. In this article we will explain what is a thermowell, why you would need one, and what process you should follow when selecting a well for your project.thermowell
Thermowells are tubular fittings used to protect temperature sensors in industrial processes. They consist of a tube closed at one end and mounted in the process stream. A temperature sensor such as a thermometer, thermocouple or RTD is inserted in the open end of the tube. The process fluid transfers heat to the thermowell wall, which in turn transfers heat to the sensor.

Embracing LEAN Systems

D&N Engineering was founded on the vision “willing to take on any challenge, large or small” and it still rings true today. So in early 2014 when faced with the challenge of staying competitive in an increasing difficult market we did what we do best… found a solution. With the help of our friends from the Institute for LEAN systems (ILS) we were introduced to LEAN, the “systematic method for the elimination of waste within an enterprise”.

The Hard Facts of Sheath Material

A Thermocouple is a versatile temperature measurement device and can be exposed to extreme environments. When this is the case, your choice of Sheath material is most important as different materials come with varied temperature ranges, melting points and chemical resistance.
This week we will look at the different sheath material available and provide you with some useful information on the 3 most common.
