MODEL P16C Very Low Differential Pressure Transducer
Typical applications include air conditioning control systems, air flow control
measurements, and positive air pressure control systems. This unit is also available with an output proportional to the square root of the measured differential pressure for use in flow measurements.

LOAD GRAPH
* Instability with time, zero
shift with temperature and
acceleration response are
inversely proportional to the full scale setting i.e. at 40% rated range as full scale. They are 2.5 times as great as at rated full scale.
* Repeatability is consecutive runs with all conditions alike.
* Performance limits are
for rated range. Turn down
from rated range will cause a proportional increase in errors.
