APPENDIX A – SSP SEALS
V-RING CONTACT SEALS (with reference dimensions)
Optional temperature sensor for the bearings on the SSP design
Using an ohmeter, the resistance can be measured from the leadwires, and can be translated to a temperature reading. A transmitter
can also be attached to the wires to customize output readings.
When using long lead wires, errors in readings occur due to resistance in the wires. Approximate errors can be calculated using the
following
equations:
R = L X N
WHERE: L = LENGTH OF WIRE (FT)
N = RESISTANCE OF WIRE (OHMS/FT)
E = R / T
WHERE: E = ERROR (°C)
T = TCR OF SENSOR X ELEMENT RESISTANCE (OHM/°C)
Another method to reduce lead wire error is to connect the 2-wire rtd to a wheatstone bridge circuit.
