Thermocouple And RTD Input Two Wire Transmitter With 4.5 Digit Display Model SC5010

Features

Description

The SC5010 provides a DC output current (4/20 mADC) proportional to the temperature as measured with a thermocouple or RTD, using microprocessor based, digital circuitry in a "hockey puck" style case. The output can be linearized for both thermocouples and platinum RTDs, and the LCD display indicates temperature in °C or °F when operated in the linearized mode, or output current when in the  non-linearized mode.

The input and output are isolated.

The user may select thermocouple types J, K, R, S, T, E, or N, or 100 ohm Pt RTD 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 4 1/2 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 4/20 mADC output.  Even if the output goes overrange, the display will continue to accurately indicate the sensor temperature.

Linearization is accomplished via a 256 point look-up table program.

Four different user configuration methods are available. They are:

    1. On-board configuration in linearized mode via keypad and display.
    2. On-board configuration in non-linearized mode via keypad, display, and
        temperature tables.
    3. Configuration via keypad using a calibrator.
    4. Configuration using a Personal Computer and the CIK005A.
