Notes
1. Pressure ranges can be considered bidirectional, e.g., an 8507C-5 can be used to
measure +or - 5 psig. Sensitivity on the positive direction is typically within 1% of
sensitivity in the negative direction. Sensitivity calibration provided with each unit is for
the positive direction.
2. 1 psi = 6.895 kPa = 0.069 bar.
3. FSO (Full Scale Output) is defined as transducer output from 0 to + full scale pressure.
4. Zero Measurand Output (ZMO) is the transducer output with 0 psig applied.
5. Significantly higher thermal transient errors occur if the excitation voltage exceeds
10 Vdc. For sensitive phase change studies, many users reduce the excitation to 5 Vdc
or even 1 Vdc.
6. Equiv. PSI Per ISA-37.10, Para. 6.7, Proc. 1. The metal screen partially shields the
silicon diaphragm from incident radiation. Accordingly, light incident at acute angles to
the screen generally increases the error by a factor of 2 or 3.
7. Warm-up time is defined as elapsed time from excitation voltage “turn on” until the
transducer output is within ±1% of reading accuracy.
8. Use of excitation voltages other than 10.0 Vdc requires manufacture and calibration at
that voltage since thermal errors increase with high excitation voltages.
9. Units can be compensated over any 200°F (93°C) span from -65°F to +225°F
(-54°C to +107°C) on special order.
10. Maintain high levels of precision and accuracy using Endevco’s factory calibration
services. Call Endevco’s inside sales force at 800-982-6732 for recommended
intervals, pricing and turnaround time for these services as well as for quotations on
our standard products.
11. To extend vent tube, use Tygon® micro bore tubing, “.020 I.D X .060 O.D.”, -31ºC (-25ºF)
to +85ºC (185ºF), which is available from Cole-Parmer. For broader temperature range,
use silicone tubing.
Note: Tighter specifications are available on special order.
