Service Department

Our service department is equipped with the professional measuring and diagnostic equipments. Our service center provides the standard warranty and post-warranty service for the complete range of the DwyerOmega (OMEGA Engineering, NEWPORT Electronics and more...) products, including calibration in our accredited calibration laboratory.

Furthermore, the service center is equipped with the professional micro TIG welding technology with the adjustable power ranging from 0.5 to 200 watts for the precision welding as well as the machining technology for the sensors repearing such as the thermocouples or Pt100 and the other types of sensors and devices. The equipment of the service center also includes calibrators, a signal generator, an oscilloscope and other equipment needed for repairs and fault diagnosis.

More demanding repairs of the equipment, that we are unable to repair in our service center, are provided directly at our manufacturing plants.

For the critical applications where time plays a great role, we are able to lend you the same device for free. Alternatively, if possible, suggest a replacement solution with the same functionality that will help you bridge the repair time of your device.

Complaint Form (problem description)

For the goods sent under the warranty, please always attach a complaint form. For post-warranty repairs, it is also advisable to fill and send the form together with the goods. Please provide a detailed description of the problem, responsible contact person and the return address.

Please send the goods clean, thoroughly packed, preferably in original packages with all the accessories provided, so that it will be not damaged during the transport.

If the device has been in contact with the hazardous substances, most often for flowmeters, please state this fact in the form.

How is Temperature Measured?

How is Temperature Measured?

Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs Pt100 and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.

Understanding Thermocouple Accuracy Drift

Understanding Thermocouple Accuracy Drift

One constant in industrial processing is that accuracy drift in a measurement device is something to be avoided. For critical applications, where temperature measurements directly influence performance, even a slight drift in the accuracy of a device like a thermocouple can lead to significant issues.

Yet, consumers continuously find that many of the thermocouples out there on the market end up needing to be recalibrated or replaced all together (sometimes after an annoyingly short period of time) due to, you guessed it, accuracy drift...
