Installation
Install the pressure transducer
To install the pressure transducer, you will connect it to the Pressure Measurement fitting and
connect the wiring to the Thermo Scientific Antaris IGS Temperature Controller.
On the Manual Pressure Control system, the pressure transducer should be installed horizontally, as
shown in the figure below.
On the Automatic Pressure Control system, the pressure transducer should be installed vertically. It
is okay if the pressure transducer is at a slight again, as shown in
Figure 3-7

To connect the pressure transducer
1. Connect the pressure transducer to the Pressure Measurement outlet on the rear panel of the
drawer. The pressure transducer must be installed upright or horizontally (not at an angle and not
upside down), as shown in the previous image.
A Swagelok VCR sealing washer for the connection is provided in a plastic bag attached the
pressure measurement outlet.
a. Pull the threaded fastener out to the end of the pressure measurement tube.
b. Place the provided washer into the threaded fastener of the pressure transducer.
c. Attach the pressure transducer to the pressure measurement tube and tighten by hand.
d. Using an adjustable wrench, tighten the nut. Be careful not to bend or damage the pressure
measurement tube.
2. Connect the data cable from the pressure transducer to the Pressure Data In port on the tem-
perature controller. See the user manual for the temperature controller for more information on
