Analog output
The 902B transducer provides a voltage output as function of pressure. The 902B is available with a
selection of factory configured outputs determined by the part numbers listed below. The default analog
output calibration is “14” corresponding to the Linear10 functions stated below for the units: torr, mbar and
pascal.
