MadgeTech Demolition Derby Car Records Crash Data

Posted on

Here’s a throwback from six years ago today, when MadgeTech engineers and staff installed several data loggers in a car destined for destruction. MadgeTech was proud to sponsor a Demolition Derby car for the 2013 Hopkinton State Fair, driven by then 20-year-old, Roddy Tanner, of Warner.

Installed in Roddy’s blue Ford LTD were an UltraShock-50G, two TSR101-50G shock loggers for monitoring the G forces of the crashes, three TC101As for monitoring the temperature of the engine block, radiator and transmission and a Pulse101A for monitoring the engine RPMs. The loggers were secured to various positions within the vehicle using industrial strength high powered magnets. There’s no need to worry about the shock loggers themselves, their steel enclosures are built to be virtually indestructible.

Since then, MadgeTech has released the new UltraShock, available for preorder now, which replaces all of our older shock models. The UltraShock contains powerful improvements and an all-in-one functionality capable of recording shock, temperature, pressure and humidity. Featuring a smaller, lighter design, the UltraShock has a battery life of up to 90 days and uses a USB-C cable, making it easily rechargeable.

Temperature is the Key to Candy Making

Posted on

Like a kid in a candy shop, we get excited by the endless options of sweet treats surrounding us. Lollipops, butterscotch, gummies and fudge all have a different appearance, taste and texture. But they do have one thing in common, they all originated from just two simple ingredients: water and sugar.

As the water and sugar cooks, the water boils and begins to evaporate into the sugar, forming a syrup. It’s at this point when the temperature starts to rise that it is determined for how long mixture is boiled, depending on the type of candy being made.

The final outcome of the candy depends on the sugar concentration or the syrup. Higher temperatures with greater sugar concentrations usually result in hand candies, whereas, lower temperatures result in softer candies.

Temperature control is critical when it comes to candy making, so having an accurate thermometer can make all the difference. While the common candy thermometer can measure temperatures up to about 160 °C, data loggers designed for commercial candy production can withstand higher temperatures. Keep in mind, if the thermometer or data logger rests on the bottom of the pot, it will skew the results!

MadgeTech offers several temperature monitoring solutions for commercial candy makers. The HiTemp140 can go into a boiling pot to record temperatures during the cooking process, but for applications above 140 °C the HiTemp140 must be used in conjunction with a thermal shield. For instantaneous, real-time readings, the RFTCTemp2000A accepts a variety of thermocouples allowing for users to monitor extended temperatures.

Why Do I Need to Send My Logger in for Annual Calibration?

Posted on

All measurement equipment can drift over time in different ways. Some factors that can influence the amount of drift include environmental exposure, number of uses, handling, storage, age and power supply. These are not all the possible factors but a small list to consider.

Many manufacturers will suggest that measurement equipment should be calibrated at a specific interval, the important thing to understand is this is just a suggestion. Ultimately a calibration interval should be determined by the user based on the factors that can influence drift, the requirements for the process, the allowable risk in the process and previous calibrations once they are available.

To determine the ideal calibration interval for equipment you will need to have a reasonable starting point. Using the manufactures recommendation is a common practice however not the only method to understand best practice. Using a short calibration interval to begin with to understand short term drift may be helpful or if you are trying to maintain a tighter tolerance. Starting with short intervals and adjusting over time based on calibration results allows you to gather more information about your equipment’s ability to maintain accuracy over time and exposure to your application. On the other hand, long intervals make it more difficult to know at what point your equipment drifts and can be costly depending on how critical the measurement is.

After you have a few calibrations completed on your equipment you can start to make a determination as to whether you need to adjust your interval based on the results. For example, if you have been calibrating annually and the results show that your equipment is out of your process tolerance you may want to consider calibrating more frequently. If the results are still within tolerance each year you may consider extending the time between calibrations or staying with one year knowing that your equipment will maintain the accuracy over that time.

Calibration labs can only provide data on how the equipment performs at the time of calibration under ideal conditions at a measurement parameter. In some cases, being able to monitor equipment in the conditions it is used aids in the understanding of how drift can occur. Developing a method of intermediate checks or tracking the data looking for signs of drift or irregular readings can provide understanding of the equipment’s performance under the process conditions.
