7.2 Units with Thermo Scientific
e-boxes
Units that come with Thermo Scientific e-boxes will always have
pressure transducers. The pressure sensor cord will plug into the
pressure sensor input plug on the side of the e-box. The plug location
is shown in Figure 2.4. The raw pressure signal is then routed internally
to the pressure transducer, and output as a 4-20 mA signal. This signal
is scaled at 0-10 psi. The default excitation voltage of Thermo Scientific
e-boxes is 10 VDC.
