The sensor to electronics cable is a 3ft, PVC cable for non-cooled housing and 3ft PTFE
cable when the Cooled Housing option is ordered. One end is attached, at the factory,
to the sensor head. The other end has a pair of wires and a shield (ground) wire.

The SilverU sensor can be used in 3 different ways as shown below. To use the
4-20mA output, connect the SilverU sensor to the controller/indicator with the 24Vdc
power supply in the loop using the following table and connection diagram as a guide.
The maximum loop impedance is 900 ohms. note: the silveru sensor must be
grounded at only one point, either the cable shield or the sensor housing.

Alternatively, to use the USB output, connect the SilverU sensor to a PC using the
cable provided. No external power supply is required when using the USB output. The
SilverU sensor can also be used with both the 4-20mA loop and USB connected,
provided that the negative terminal of the 24Vdc power supply being used is not
grounded. note: the silverview software must be installed before connecting the
sensor to a pc.

configuration
• Setting Temperature Units
Temperature units can be set on the main temperature panel by pressing °C or °F.
• Setting Output Processing
The temperature range for the 4 to 20mA output, the averaging period and the peak/
valley hold processing can be set by using the main program menu to select:
[Setup] → [Output Processing]
The temperatures corresponding to 4 and 20mA can then be set (minimum -40°F
(–40°C), maximum 1832°F (1000°C), minimum span 180°F (100°C), maximum span
1832°F (1000°C)).
To minimise the the effects of temperature fluctuations, noise etc on the output
signal, the averaging period can be set between 0 and 60 seconds.
If required, Hold Processing can be applied by setting hold mode to Peak Hold or
Valley Hold and setting a hold period between 0 and 1200 seconds.
• Setting Target Emissivity
To set an Emissivity value for the SilverU Sensor, use the main program menu to
select:
[Setup] → [Emissivity]
Emissivity can then be set to a value between 0.10 and 1.0, or selected from a pre-
set list of materials by selecting [Data].
