Barometric pressure sensor (extended range)
The sensor PCTPRxxx consists of a piezoelectric transducer based on the characteristic of silicon to generate an electrical potential difference proportional to the mechanical stress applied on its surface.
This type of transducer is characterized by extremely accurate performance, stable measurements of atmospheric pressure, with excellent repeatability and low hysteresis.
An electronic amplifier circuit normalizes the output signal in the most common formats used by acquisition circuits (0-1V, 4-20mA).
An electrical circuit for compensating the temperature allows more accurate measurements.
The sensor is housed inside a box having a high degree of resistance to contaminants.
On one side of the box there is a conduit for access to the terminal board of connection.
For outside application may be provided a special cover with static port so as to reduce the overpressure induced by the effect of the wind.
