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.
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.

Overpressure: The maximum pressure which may safely be applied to the product for it to remain in specification once pressure
is returned to the operating pressure range. Exposure to higher pressures may cause permanent damage to the product.
2
Burst Pressure: The maximum pressure which may be applied without causing escape of pressure media. The product should not
be expected to function after exposure to the burst pressure.
