The Laurel thermocouple meter is factory calibrated for type J, K, T, E, N, R and S thermocouples for exceptional accuracy and repeatability. The entire span of each thermocouple type is presented in a single range. The thermocouple type, unit of measure (°C or °F), resolution (1° or 0.1°), and upscale or downscale open sensor indication are selectable from the front panel or via the serial interface. Display in Kelvin or Rankin is selected by offsetting the Celsius or Fahrenheit ranges. Cold junction compensation is standard.
All ranges for all temperature sensor types are digitally calibrated at the factory, with calibration factors stored in an EEPROM on the signal conditioner board. This allows temperatures sensors and signal conditioner boards to be changed in the field without recalibrating the meter.
High read rates at up to 60 or 50 conversions per second while integrating the signal over a full power cycle are provided by Concurrent Slope (US Pat 5,262,780) analog-to-digital conversion. High read rates are ideal for peak or valley capture, real-time computer interface, and control. Peak and valley values are automatically captured. These may be displayed via a front panel pushbutton command or a control signal at the rear connector, or be transmitted as serial data.
Digital filtering is selectable for electrically noisy environments, including a batch averaging filter and an adaptive moving average filter which provides a choice of 8 time constants from 80 ms to 9.6 s. When a significant change in signal level occurs, that filter adapts by briefly switching to the shortest time to follow the change, then reverts back to the selected time constant. In a selectable Auto filter mode, the filter time constant is automatically selected based on detected signal noise.
