Thermal Span or Sensitivity Shift signifies the maximum amount of span that will change at any measurement point within the compensated temperature range.
Total Error Band (TEB) is the difference between the most negative and most positive deviation from the true measurement, determined from the combination of all known errors for a sensing device, within the constraints of the measurement and operating temperature range. Typically in the case of a pressure measurement device for example, the total error […]
Thermal Zero Shift (TZS) is the maximum amount the output or reading at the null measurement point might deviate over the compensated temperature range
Thermal Hysteresis is the measured change in output or reading at a specific measurement point taken during a sequence of increasing and decreasing temperature.
Temperature Error Band (TEB) is the error derived from the most positive and negative deviation of all measurement points within a measurement range over the operating or compensated temperature range.
Temperature Error is the deviation of a measurement reading caused by a change in media or environmental temperature.
Temperature Compensation is a correction applied to a measurement instrument to reduce errors attributed to temperature changes in a process media which is being measured or in the surrounding environment that the instrument is being used.
Referred Temperature Error is the max deviation expressed as a +/- %FS from measurements taken at a defined temperature.
The compensated temperature range defines the limits of operation for a specified measurement accuracy. e.g. A pressure sensor has an accuracy of 0.25% full scale over a compensated temperature range of -20 to +80 degC. Since temperature errors are often significant for many measurement devices, a manufacturer will incorporate digital or analogue temperature compensation. If the measurement device is […]
I have a 10bar pressure transducer with a 4-20mA output which is showing a random variation across a span of 0.3mA (+/- 1.5mA) at a fixed pressure.
I‘m having a problem zeroing a submersible pressure sensor. Before placing it in the water, the zero offset is trimmed on the indicator, and then it is submerged to full range depth of 10 metres. During the first few minutes we notice that the full scale reading drifts by about 10mm in the negative direction […]
