FUNCTION
The DPIA Two-Wire Differential Pressure Transmitters are
equipped with an integrated piezo-resistive pressure
transducer designed so that the pressure to be measured is
applied to a thin membrane made of monosilicon, thus
deflecting it. The semiconductor resistors on the membrane
detect this mechanical deflection and generate an electrical
output signal. The arrangement of the resistors
simultaneously compensates for the temperature response.
The signal of the pressure transducer is converted into the
output signal by high-gain operation amplifiers.
The electrical output signal changes within the specified error
limits in proportion to the applied pressure.
NOTE: All DPIA Two-Wire Differential Pressure
Transmitters are factory pre-set to a response time
of 1s (slow).
NOTE: All DPIA Two-Wire Differential Pressure
Transmitters are factory pre-set to the lower
pressure range 1.
