The SC5000 series of products provide a DC output current 4/20 mADC proportional to a thermocouple or RTD, using microprocessor based, digital circuitry in a “hockey puck” case. The output can be linearized for both thermocouples and platinum RTDs, and the SC5010 LCD display indicates temperature in °C or °F when operated in the linearized mode, or output current when in the nonlinearized mode.The input and output are isolated. The user may select thermocouple types J, K, R, S, T, E, N or 100 ohm Pt RTDs as the input sensor. RTD connections for 2-wire, 3-wire and 4-wire sensors are provided. The transmitter compensates for the lead wire resistance in the 3-wire configuration and provides true measurement of the resistive element without lead wire error in the 4-wire configuration.

The SC5010 4½ digit display is an accurate temperature indicator that functions over the entire range of the selected sensor. Its display capability is independent of the selected temperature range for the 4 to 20 mADC output. Even if the output goes overrange, the display continues to accurately indicate the sensor temperature. Linearization is accomplished through a 256 point “look up table” program.

The SC5010 can be configured by the user through four different methods.
These are:

  1. On-board set-up via membrane keyboard and display in the linearized mode.
  2. On-board set-up via membrane keyboard, display and temperature tables in the nonlinearized mode.
  3. Set-up via membrane keyboard using a calibrator.
