Table 11 - Sensor Types For Pv3 Process Temperature Input - Honeywell SmartLine Multivariable SMV800 Series User Manual

Background
Every thermocouple requires a hot junction and a cold junction for operation. The hot junction is
located at the point of process measurement and the cold junction is located in the transmitter
(internal) or at an external location selected by the user. The transmitter bases its range measurement
on the difference of the two junctions. The internal or external temperature sensitive resistor
compensates for changes in ambient temperature that would otherwise have the same effect as a
change in process temperature.
If you configure CJ source as fixed, you must tell the transmitter what cold junction temperature to
reference by typing in the temperature as a configuration value. For internal cold junction
configuration, the transmitter measures the cold junction temperature internally.
Background
You can have the transmitter provide a linear output which is linearized to temperature for PV3 input,
or a nonlinear output which is proportional to resistance for an RTD input, or millivolt or volt input
for T/C input. Also, if you do switch from linear to non-linearized or vice versa, be sure you verify
the LRV and URV settings after you enter the configuration data.
Sensor Type
Identify and select the type of sensor that is connected to the transmitter as its input for process
temperature PV3. This will set the appropriate LRL and URL data in the transmitter automatically.
Table 11 shows the pre-programmed temperature sensor types and the rated measurement range limits
for a given sensor selection.

ATTENTION!
Whenever you connect a different sensor as the transmitter's input, you must also change the sensor
type configuration to agree. Otherwise, range setting errors may result.
