Five easy steps for choosing an industrial temperature readout and probe

To calibrate an industrial temperature sensor like a PRT, RTD, thermistor, or thermocouple, you put the sensor into a stable industrial temperature readout like a dry-well, furnace, or calibration bath, and then compare the sensor?s output to the output of a reference standard probe connected to a thermometer readout. There are many different types of reference standard probes and thermometer readouts, and many ways to combine them, so knowing what to purchase can be a little confusing. We can help simplify the process.

In this blog post, we share five steps to follow when choosing a reference standard probe and a thermometer readout for calibrating industrial temperature sensors.

1. Ask yourself these questions before choosing the readout.

  • What kind(s) of temperature sensor(s) will you be calibrating? ? Will the readout be used in the field or in a calibration laboratory?
  • How many channels are needed on the readout?
  • Do you need to log data? See data in graphic format? Record data?
  • Do you want to automate the calibration process?

2. Consider the temperature range of the sensors you?ll be testing and the required immersion depth of the reference probe.
The reference probe you select should cover the full temperature range of the sensors? application(s). You?ll also want to make sure the probe is long enough to reach the bottom of the dry-well or the sensing element of the sensor under test in a bath.

The reference probe and the sensor under test should be at the same temperature during a comparison calibration. Therefore, the sensing elements of the reference probe and the sensor under test need to be aligned vertically. Both also need to be immersed sufficiently in the dry-well or bath to ensure accurate measurements. A general rule is that the minimum probe immersion needs to be 15 times the probe diameter plus the sensor length.

3. Determine the combined system accuracy of the readout and reference probe.
We can provide system accuracy data for various combinations of Fluke Calibration readouts and probes. For other manufacturers? products, please check the specifications.

4. Make sure that the readout and probe, used together as a system, provide the accuracy needed to calibrate the sensor under test.
The calibration system needs to have a higher level of accuracy than the temperature sensor being calibrated. A test accuracy ratio (TAR) of 4:1 or 3:1 is commonly used as a guideline.

5. Decide if additional calibration is required.
In addition to a factory calibration for the probe and the readout, you may want to verify the performance of the probe and readout together with a system calibration. A system calibration provides a higher level of assurance that the instruments are performing as expected when combined together and all probe coefficients are entered correctly into the readout.

Are Your PCB Design Tools up to Speed? (A Comparison)

Choosing a PCB design tool is a bit like buying a?car. You don?t do it every year. Your decision is
based on long-term value. You can?t afford for it?not to work, and you need to trust your dealer to
provide good service.

Getting stuck with a lemon is no one?s idea of a?good car deal, and it shouldn?t be acceptable for
PCB design tools either. Did your vendor hook you?with a great deal but then raise their prices year
after year? Did your vendor claim to handle?complex design challenges, but then leave you
with a product that runs out of steam or fails to?provide the technology you need? Are you
missing capabilities or being forced to rely on?third-party tools? It might be time to reconsider
your PCB design tool choice. Read this paper to?see how your tools stack up against the?competition

PCB Design Then and Now

It?s hard to believe that nearly three decades have past since I designed my first printed circuit boards. I can still recall how impressed I was with the first CAD system I?d operated. It was in a futuristic ambient-lit computer room where six or so minicomputer based Calma Systems were installed.

Each Calma workstation included a digital read-out of x-y coordinates illuminated in red located in the upper right corner of the huge digitizer table. Each station also included a console complete with mechanical keyboard and green monochrome CRT?s.

This image Calma(courtesy of David Weisberg) gives you an idea of the floor space taken-up by the Calma system.? A separate ?computer room? complete with a raised floor hiding all the AC ducts and cabling housed all the data storage systems that served and backed-up the workstations. There was also a huge HP plotter used to print out each layer of digitized routes that would eventually be scaled and photographed on to clear film in the lab located across the hall. Sound familiar?

You don?t have to have been in the PCB industry for decades to see the evolution of EDA tools for PCB design. The industry has come a long, long way from hand-taping designs and digitizing hand-drawn layers as done with the Calma systems that we literally used to build rooms around. We now use powerful desktop tools installed on laptops and carry them around in backpacks that ?usually? fit neatly under the seat in front of you on an airplane.

PCB designers? responsibilities have evolved proportionally over the decades. A design flow where individuals may have been solely responsible for the schematic or just symbol creation or only the layout of the design without any involvement with other individual tasks in the design flow are long gone.

Today, we must consider every aspect of the design throughout the entire flow. That is, interest in every component, every layer, every trace and every via. We consider signal integrity, we simulate and we validate. We know where the PCB is installed and design with EMI and thermal influences in mind. We collaborate directly with mechanical CAD tools and we analyze completed designs utilizing DFMA tools developed to ensure first-pass manufacturing success.

?PCB design, the methodology of the past, has become the entry point to the wonderful new world of System Design Automation (SDA). PCB itself is being teamed-up with MCM design; 2D, 2 & ?D design, and 3D design; MEMS Design and Mechanical Design. This is giving Mentor and Cadence a door to the future.?
