Product Selection Guide

Strain Gauge Meters Weight, load cell, force, stress and tensile strength transducers typically use strain gauge elements in a bridge configuration. The required digital panel meters are strain gauge and load cell meters whose capabilities include high gain, multiple noise filtering modes, zero and span adjustment, and a built-in bridge excitation supply to power strain gauges or load cells.

Weight, load cell, force, stress and tensile strength transducers are also available with a conditioned process signal output (such as 4-20 mA or 0-10 V) or a pulsed / AC output. These signals can be displayed by a process meter or pulse-input rate meter. Capabilities available with the Laureate load cell panel meters, process meters and pulse input rate meters include high read rate, peak hold, custom curve linearization, and rate from successive readings.

5-digit DC digital panel meter with a most sensitive full-scale input down to ±20 mV. A built-in isolated 10 Vdc excitation supply powers four 350-ohm load cells in parallel. 4- or 6-wire bridge connection with ratiometric operation cancels variations in the excitation supply. Multiple selectable filtering methods assure a stable display. Programmable zero and span using three methods: scale and offset, two-points, and system-level calibration using actual transducer signals. Auto-tare with tare value stored in memory for weighing applications. Optional analog output, relays, and data I/O. Five 0.56" (14.2 mm) high digits, 1/8 DIN case.

Load Cell Meter

A special firmware version for scale / weighing applications of Laureate digital panel meters with the load cell or process signal conditioner . Capabilities include display to 999,990 with fixed right-hand zero, auto-zero display function, auto-tare or manual tare with tare value stored in non-volatile memory, setpoint control with offset compensation for filling application, display toggle between gross or net weight, count by 1, 2, 5, 10, 20, 50 or 100 with rounding, and easy scale calibration using a known weight. Optional analog output, relays, and data I/O. Six (five active), 0.56" (14.2 mm) high digits, 1/8 DIN case.

Scale / Weight Digital Panel Meter, Model LW

Suitable for load cell and strain gauge applications when higher signal levels are available. All capabilities of the Laureate 5-digit Load Cell meter, except that most sensitive full scale is ±200 mV and bridge connection is limited to 4 wires.

Process Meter and Scalable Digital Panel Meter

4- or 6-digit large-digit displays with a digit height of 2.2" (57 mm), 4" (102 mm), 6" (150 mm), or 8" (200 mm) for long viewing distances. Available for strain gauge signals. Includes 10 Vdc, 120 mA excitation output to power up to four 350-ohm load cells in parallel. Optional dual 5A relays, analog output, and serial data output. Choice of display brightness and cases for indoor or outdoor mounting.
