A TS-58011-774 Platinum RTD sensor is wired to a DMS Microsmart MSC-MPC controller.
What is the maximum and minimum offset value considered acceptable for the sensor to operate accurately?
Can the maximum wire length exceed 200 feet?
TAC I/A Series
DMS Microsmart controllers
A large offset of almost 6 degrees must be used to make the reading accurate with a handheld temperature calibration device.
There is no maximum and minimum offset value. However, the length of wire used should not exceed 200 feet. The recommended wire type is Belden #9501 (AWG24). If these two wiring requirements are met, then the offset value used will not be "large".
Below is a link to the sensor's installation guide. Review "Software Setup" starting on page 3 to understand how to calculate the amount of error introduced to the temperature reading by the installed wire. Use the temperature/resistance table on page 5 to verify that the sensor is accurate then use an appropriate offset value to eliminate the error introduced by the sensor wire.
If necessary, use SOCALC on page 4 to develop custom SCALE and OFSET values.
