Notes:
1.
All specifications apply at 25 °C and under operating conditions unless otherwise noted.
2. Operating Temperature Range: The temperature range over which the product will produce an output proportional to pressure but may not remain
within the specified performance limits.
3. Storage Temperature Range: The temperature range over which the product may safely be exposed without excitation or pressure applied. Under
these conditions the product will remain in specification after excursion to any temperatures within this range. Exposure to temperatures outside
this range may cause permanent damage to the product.
4. Compensated Temperature Range: The temperature range (or ranges) over which the product will produce an output proportional to pressure
within the specified performance limits.
5. Overpressure: The absolute maximum rating for pressure which may be safely applied to the product for it to remain in specification once pressure
is returned to the operating pressure range. Exposure to higher pressure may cause permanent damage to the product.
6. Burst Pressure: The maximum pressure that may be applied to the product without causing escape of the pressure media. The product should not
be expected to function after exposure to any pressure beyond the rated burst pressure. This rating is also the case burst rating of the product.
7. Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at 25 °C.
Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.
8. Offset Error: the maximum deviation in the output signal obtained when the reference pressure is applied at 25 °C relative to the ideal transfer
function.
9. Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the
pressure range.
10. Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range. Includes
all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect on span,
and thermal hysteresis.
11. Response Time: The response time of the transducer is the maximum amount of time that the transducer will take for the transducer to output a
change from 10% to 90% of full scale in response to a 0% to 100% full scale step input pressure range.
12. Turn On Time: Duration from power applied until first valid output.
13. Life may vary depending on the application in which transducer is used. Contact Honeywell Sales and Service for Mean Time to Failure (MTTF)
data based on customer-specific usage profile.
