Differential low pressure sensor
max. 413.7 bar | 115C

which consists of one stationary plate and a common moving plate shared by the two capacitors. With the common plate
moving as a result of application of external pressures, the differential capacitance system is formed: |when the external
pressures are applied to this system, one capacitor increases its capacitance, while the other decreases its capacitance
at the same time. As a result, the system is sensitive to the applied external pressures.
115C makes use of this system to measure the differential pressure (D). Thanks to its large diameter of the diaphragm
and high accuracy of the capacitors, 115C DPS is capable of measuring very low differential pressures down to 0~15
mbar. The 115C DPS can sustain a system pressure up to 312 bar for differential pressure applications with a measuring
accuracy up to 0.2 %fso (fso = full scale output).
Model 115C is typically used to build intelligent pressure transmitters with accuracy up to 0.075 %fso, and for OEM
applications which may require by the customer for certain modifications on its mechanical interface.
