Pressure transducer ranges
Pressure sensor ranges(1), bar a (psi a)
Full scale operating pressure Maximum over-range pressure
bar a psi a bar a psi a
2 30 4 60
7 100 14 200
20 300 41 600
34 500 69 1000

Note:
(1) To maximize accuracy, specify the lowest full scale operating pressure range for the
application. To avoid damage, the flowmeter must never be subjected to pressure above the
over-range pressure shown above.
