1.2. Specifications

2
Pressure capsule
Can be put until 4 pressure capsules in the PCA-570, with ranges varying of 25 mbar until 700 bar.
(*) Absolute pressure (ranges 3 to 8), gauge, vacuum (only for range 3), composed (of range 3 to 8) or differential (of range 0 to 2).
(**) Percentage of full scale.
Note: The differential capsule occupied two pressure sockets.
Obs.: Optional BR (Barometric Reference – 15 psia)
Sensor for measurement of barometric pressure. Can be used for simulate the indication of absolute pressure in the other
ranges. Accuracy of ± 0,02 % FS (15 psia).
The values of accuracy includes a period of one year and ambient temperature of 20 and 26 °C. Outside
this range, the thermal stability is the 0,005 % FS / °C, with reference to 23 °C. Such values are achieved through
compensation algorithms of temperature about pressure measurement.
