Connecting a TS-58011-774 Platinum RTD Sensor to a DMS Microsmart MSC-MPC controller.

[Product_Support]

Issue

When wiring a TS-58011-774 Platinum RTD sensor to a DMS Microsmart MSC-MPC controller, what are the acceptable offset values for accurate temperature readings? Can the wire length exceed 200 feet?

Product Line

TAC IA Series

Environment

• DMS Microsmart controllers
• TS-58011-774 Platinum RTD sensor

Cause

A significant offset (approximately 6°F) was required to match readings with a handheld calibration device, raising concerns about wiring length and sensor accuracy.

Resolution

• Offset Values: There is no fixed maximum or minimum offset value. Proper wiring minimizes the need for large offsets.
• Wire Length: Do not exceed 200 feet.
• Recommended Cable: Belden #9501 (AWG24).
• Calibration Steps:
  1. Review the sensor installation guide (F-24874) for Software Setup (page 3).
  2. Use the temperature/resistance table (page 5) to verify sensor accuracy.
  3. Apply appropriate offset values to correct wire-induced error.
  4. If necessary, use SOCALC (page 4) to create custom SCALE and OFSET values.
