THERMOCOUPLES

Whatever the medical device application for which a thermocouple is used, optimum accuracy and economy are likely to be hallmarks of its performance only if the following recommendations and advisories are heeded:

• Select the type that best matches operational requirements.
• Provide adequate protection against environmental challenges.
• Use the largest practical size.
• Install the device in a location that ensures truly representative measurements.
• Provide for sufficient immersion depth.
• Avoid changing the immersion depth.
• Recognize and adapt to the effects of cyclic heating on measurement accuracy.
• Establish a preventive maintenance program.
• Use wiring components that match the device calibration.
• Determine whether the chief goal is accuracy or repeatability of measurement.
• Use limit sensors to ensure safe system operation.
• Avoid electrical noise.
