Laureate™ panel meters with the temperature signal conditioner board provide highly accurate, stable and repeatable temperature indication for multiple thermocouple types and 100 Ohm platinum RTDs. The meter accepts the outputs of types J, K, T, E, N, R and S thermocouples, plus 100 ohm platinum RTD’s with DIN alpha of 0.00385 and ANSI alpha of 0.003925. The thermocouple or RTD type, range and resolution (1° or 0.1°) are selectable from the front panel or via the serial interface. Display in Kelvin or Rankine can be selected by offsetting the Celsius or Fahrenheit range.

Cold junction compensation automatically corrects for temperature variations at the thermocouple reference junction at the meter. Open sensor indication is standard and may be set up to indicate either upscale or downscale. RTD excitation is provided by the meter. RTD connections can be of the 2-, 3- or 4-wire type. For 3- and 4-wire connections, the meter automatically compensates for lead resistance of the sensor.

All ranges for all temperature sensor types are digitally calibrated at the factory. This eliminates the need for field calibration or drift caused by potentiometers found in non-microcomputer based meters.

All Laureate meters allow exceptionally fast read rates. Concurrent Slope (Pat 5,262,780) is a method of analog-to-digital conversion that allows up to 60 conversions per second while integrating the input over a full power cycle. Fast read rates provide true readings and fast response for control applications. Display of peak value is standard.

Plug-in isolated analog output, dual-setpoint controller, RS-232/485 communications, and parallel BCD output boards can upgrade the Laureate from stand-alone monitor to system interface and control. The Laureate temperature meter can serve as a highly accurate, isolated, 4-20 mA transmitter.

Laureate panel meters are available with a red or green LED display. Blanking of leading, non-significant zeros simplifies reading. The 1/8 DIN case is water
