Good insulation resistance in a metal sheathed platinum resistance thermometer (PRT) probe is important for obtaining accurate and stable temperature measurements. If a probe is cycled frequently between hot and cold temperatures, its components become fatigued over time, and moisture can leak through the sheath seal at the probe handle. This is a common cause of decreased insulation resistance and noisy measurements.Cold temperatures allow moisture to leak through the sheath seal into the probe’s...

In any electrical installation, some current will flow through the protective ground conductor to ground. This is usually called leakage current. Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office. So what’s the problem? On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping. In extreme cases, it can cause a rise in voltage...

Power Quality loggers are often placed in the field for long periods, so most don’t have a display. Besides attracting attention and so increasing the chance of theft, a display is simply not needed as you don’t normally use a logger for troubleshooting. Successful analysis is therefore all about gathering data.Somehow, you need to communicate with the logger. You need to tell it what and how to measure, and then download the data. With no display, a logger’s communication links are critical,...

What is IEC 61000-4-30 standard?The IEC 61000-4-30 standard ensures that the measurement results from Power Quality analyzers and loggers of different makes and models match up; so measurement results are comparable without any doubts. This is extremely important, especially when there is a dispute about supply voltage quality between different parties going on. To comply with this standard, the instruments should measure and evaluate in exactly the same way. The standard covers PQ phenomena like...

Every process technician knows that the most difficult part about doing calibration in the field is getting all the hoses connected properly. Using the thread seal tape to seal up all the connections and having to take the time to reseal every time you perform calibrations. Not only is that time-consuming, but it could also lead to leak issues that throw off your measurements.In this video we're going to look at the best practices for doing a pressure calibration and what accessories, like fittings...

探索成功校准工业温度传感器的四个关键因素。

使用干井温度计校准器实现峰值性能。增强您的校准过程，以获得精准的测量结果。

Surprisingly, many people believe that once they have their temperature probes calibrated, all they have to do is hook it up to the readout, load the coefficients, and start measuring. This approach may save time initially, but can lead to significant losses, sometimes even millions of dollars, if the calibration isn't checked when you get it back. A simple shift in a PRT probe during shipping, which wasn't checked prior to use, was found to be the root cause in one such instance.What does it mean...

An infrared thermometer is a non-contact thermometer, since it doesn’t touch the surface being measured. It measures thermal radiation in the infrared region of the electromagnetic spectrum beyond where the eye can see.What Is an Infrared Thermometer Measuring?A common spectral band for measuring temperatures from below ambient up to 500 °C or 1000 °C is the 8 – 14 µm band. This is partly because at room temperature, the peak energy occurs just below 10 µm.As temperatures get higher, this...
