Total Error Band

Total Error Band (TEB) is a single specification that includes

the major sources of sensor error. TEB should not be confused

with accuracy, which is actually a component of TEB. TEB is the

maximum error that the sensor could experience.

Honeywell uses the TEB specification in its datasheet because it is

the most comprehensive measurement of a sensor’s true accuracy.

Honeywell also provides the accuracy specification in order to

provide a common comparison with competitors’ literature that

does not use the TEB specification.

FIGURE 5. TEB COMPONENTS FOR THE MIP SERIES

Many competitors do not use TEB—they simply specify the

accuracy of their device. Their accuracy specification, however,

may exclude certain parameters. On their datasheet, the errors

are listed individually. When combined, the total error (or what

would be TEB) could be significant.
