RTDs are used to monitor motor or assembly temperature. Current to the motor should be cut if motor temperature becomes excessive. Compatible temperature controllers are available from Omega Engineering and other manufacturers.
Resistance of the sensor varies with motor temperature according to the table.
Maximum Recommended Sensing Current: 10 mA
Maximum Recommended Sensing Voltage: 1 VDC
Cables: The RTD is supplied with a two wire shielded cable, the length of the cable will match that of the assembly. For example, a motor ordered with a 10 foot cable and RTD will come with two ten foot cables, one for the motor, one for the RTD. As a result the price for the cable option is doubled.
One source of set point monitors is Omega the model 6132h-RTD 0/600C. These monitors can be obtained by calling 888-826-6342 or 203-359-1660 or linking to their web site.
