Information about keeping your instruments running accurately

Posted by on in Thermodynamics

torque wrench is one of those tools found everywhere from aerospace settings to home mechanics and bicyclists’ toolboxes. Its ability to tighten fasteners accurately to a particular force makes it indispensible. Torque wrenches (and other torque tools including torque transducers) must be calibrated to work properly.

b2ap3_thumbnail_Plane_torque.gifBefore using your torque wrench, make sure it has been calibrated and that its calibration date has not expired. New torque wrenches may arrive with a matching certificate of calibration traceable to NIST.

Test your torque wrench monthly for accuracy. At least once a year, your wrench should be recalibrated. In some settings, you must test for accuracy more often—perhaps before each use. Of course, as a tool, the torque wrench may be dropped or mishandled somehow. If this is the case, make sure you get it recalibrated.

InnoCal’s environmentally-controlled lab has been evaluated by A2LA and confirmed for technical competency for torque and force calibrations. We also have a fleet of mobile standards to perform calibrations on site at your facility.

When collecting data is necessary, there’s no easier way than using a data logger. If you keep track of temperature and humidity for HVAC systems, the data logger is a compact and economical way to log stats.

b2ap3_thumbnail_DataLogger.gifPharmaceutical manufacturers verify temperature readings in plants with data loggers. Some units are designed for documenting dynamic environments such as moving vehicles, trucks, containers, ships, and more. Others log voltage and current in industrial processes, productivity checks, and troubleshooting. Data loggers help save on expenses, ensure quality, and are a tool for adhering to compliance with specific industry regulations.

The common element in all data loggers is the ability to track, record, and in most cases, download or export readings to a computer. Yet if the data logger is not working effectively, its results are useless.

Make sure that your tracking data is accurate by professionally calibrating your data loggers. This ensures that you can trust the results you’re tracking.

InnoCal can handle your data logger calibrations. In our ISO17025-accredited lab, our technicians conduct hundreds of hours of training a year to stay current.

If you use a thermal imager for predictive maintenance in your plant, you recognize the value of finding hidden problems. Your thermal imaging camera can find issues that are not visible just by looking.

b2ap3_thumbnail_Thermal-Imaging.gifIn the same way, your thermal imager may look just as good as when you bought it but may not be functioning as well. The aging of electronic components over time can cause calibration shift. Your imager needs to be assessed regularly for measurement accuracy. Many manufacturers recommend recalibration at least annually.

For accurate measurement, test emissivity for the emitted energy of the object, distance to spot ratio for optical resolution, and field- of-view to determine if your target is at least twice as large as the spot size. If these three measurement processes are in line and your readings still appear off, it may be time for recalibration.

InnoCal uses radiometrically calibrated infrared calibrators to correct for uncertainties caused by emissivity and heat loss. With emissivity adjustments, a large (6”) uniform calibration surface, and tight accuracies, InnoCal’s standards can maximize confidence in your readings.

What happens when your temperature controls aren’t controlling accurately? You waste energy and produce an inconsistent product. Proper temperature control improves efficiency, helping you maximize profit and ensure the reliability of your product.

Suppose your heat stays on too long. It can damage your product, your equipment, and even be potentially dangerous. Similarly, if cooling is left on too long, it can both damage your product and cause excessive wear on supporting devices. If a compressor is overstressed, it may overheat, freeze-up, and/or fail.

The monitoring and regular calibration of temperature controllers removes the guesswork of determining how well they are operating. To keep systems running effectively, ensure that your controllers are reading and responding accurately.

Because every degree matters in temperature measurements, make sure your equipment is accurate with InnoCal's expert NIST-traceable calibrations.

When measuring temperature in industrial processes, several instruments need to be calibrated regularly to deliver verifiably accurate readings.

  • Temperature sensors are typically read by transmitters. The transmitter signal relays to a control panel which displays the temperature. All three instruments in the system require periodic calibration. The most significant errors tend to occur in the temperature sensor. Because the sensor can drift, keeping it calibrated must be a priority.b2ap3_thumbnail_Digi-Sense-12-Channel-Scanning-Benchtop-Thermometer.gif
  • Calibrating the thermometer standards used to calibrate industrial thermometers is necessary. Professional calibration supplies traceability to national and international standards. Using an accredited metrology lab ensures uncertainty levels and traceability statements have been examined and independently verified.
  • The reference thermometer, drywell and/or micro-bath heat source, and precision simulator also should be calibrated regularly by a respected lab.

Have questions about how often your industrial temperature equipment should be calibrated? Contact InnoCal. Some of the most qualified technicians in the industry work in our ISO17025-accredited lab and conduct hundreds of hours of training a year to stay current.
