Sensor Configuration page
Figure 65 shows an example Sensor Configuration page for a System 450 control system that is already configured and in
operation. On the Sensor Configuration page, you set up the hard-wire sensors (Sn-1, Sn-2, and Sn-3) and the Differential
Sensor (Sn-d), if your control system uses the Differential Control feature.
This example uses a pressure sensor (Sn-1), a temperature sensor (Sn-2), and a humidity sensor (Sn-3). This control
system example does not use the Differential Control feature. Table 9 provides descriptions, user actions, and references
for the items called out in Figure 65.

2 Site name Displays the assigned site name. You can assign a website name on the Network
Configuration page.
See Network Configuration page for more information about assigning a site name.
3 Sn-1: Sensor 1 Sensor 1 Configuration Section: Select the Sn-1 sensor type, select an offset value (only if Sn-1
is a temperature sensor), and assign a name for Sn-1.
4 Sensor type (Sn-1) Click the drop-down menu arrow to select the desired sensor type for Sn-1. The selected
sensor type provides the condition, the units of measurement, range of usable values,
resolution increments, and minimum proportional or control band for each output that
references Sn-1.
In this example, the P 500 sensor type is selected for Sn-1.
5 (Temperature) Offset (Sn-1) Enter an offset value for temperature sensors (only).
You cannot select an offset value for pressure or humidity sensors. When the sensor type is a
pressure or humidity sensor type, the 0 (zero) value in the Offset field is gray and cannot be
changed.
In this example, the Sn-1 Sensor Type is P 500 (pressure sensor). Therefore, a temperature
offset value cannot be selected.
