True AC RMS Panel Meter
The Laureate? True RMS meter offers a high accuracy 4 1/2 digit display for five voltage ranges and four current ranges. It is suited for AC applications where there is considerable distortion of current waveforms from nonlinear loading. The input is AC coupled to read only the AC component, such as ripple on a power supply.

A+B, A-B, AxB, A/B, A/B-1 Draw Meter
Arithmetic functions (+, -, /, x) on dual channels A and B open a world of possibilities. For example, add or subtract rates from two flow meters for combined scaled flow or volume. Display the ratio of flow rates, RPM of rollers, or speed of moving belts. Draw, which is obtained by subtracting 1 from ratio, can be used to indicate elongation or shrinkage of material as it passes between rollers.

Wall-Mount Enclosure
Model BOX
Model BOX is a wall-mount / bulkhead enclosure which provides environmental protection to IP65 / NEMA-4X. It comes with a 1/8 DIN panel cutout (45 x 92 mm) and can be used with 1/8 DIN instruments with a depth up to 134.5 mm (5.30"). This includes all 1/8 DIN instruments sold by Laurel Electronics.

Batch Controller (analog input)
Same capabilities as the Laureate pulse-input batch controller, but for 0-1 mA, 4-20 mA, or 0-10 V process signals, as made possible by a built-in voltage-to-frequency (V-to-F) converter. Square root extraction is standard for use with flow meters.

Laureate Duty Cycle Meter
Model FRD
Configured display ON or OFF period as a percentage of total period over a gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is selectable. Ideal for repetitive short pulses with a pulse width down to less than 1 s.

product
Time Interval Meter
The Laureate? time interval meter can display pulse width or time delay between individual pulses to a resolution of 0.2 s. It can also display average pulse width or average time delay between multiple pulses.

product
Phase Angle Meter
Exceptionally fast response (up to 20 updates per second) and high accuracy for low frequencies, such as AC line frequency. A resolution of 1, 0.1 or 0.01 is user-selectable. Accuracy is 0.01% up to 100 Hz, 0.1% at 1 kHz, and 1% at 10 kHz.

Frequency, Rate Meter, Flow Rate Indicator
Two independent scalable pulse-input channels from 0 Hz to 1 MHz. Channels may be combined arithmetically. One channel can display total while other displays rate. High read rate for control applications: AC line frequency can be measured to 50.0000 or 60.0000 Hz in a few line cycles. Ideal for use as a tachometer or readout of a turbine flow meter.

1/8 DIN Bargraph Process Display
BAR Series
30-segment bar graph meter with 75 mm (3") scale length for 4-20 mA, 0-1 mA, 0-10V, or 1-5 V signals. Optional dual-relay output.

product
Batch Controller (pulse input)
A low-cost controller for repetitive fill operations. The typical application utilizes a flow meter input and two built-in relays: a Prewarn relay slows down the pump near a preset to avoid overshoot and a Batch relay stops the pump at the preset.

product
Large Bargraph Process Display
PRO-BAR Series
50-segment bar graph meter with 250 mm (10") scale length for 4-20 mA, 0-1 mA, 0-10V, or 1-5 V signals. Available for vertical or horizontal mounting. Large bargraph is viewable over long distance in industrial environments.

product
Process Meter & Totalizer
User-scalable for display to 999,999 for 0-1 mA, 4-20 mA, or 0-10 V process signals requiring zero and span adjustment. Ideal as flow rate meter or flow totalizer for analog flow meter signals. Includes 5, 10, 24 V transducer excitation output (user-selectable).

product
Quadrature Position & Rate Meter
Accepts low-level differential or single-ended 5 V logic level quadrature signals from shaft encoders to display scaled position or scaled rate. One, two or four transitions may be counted at a maximum combined rate of 250 kHz and be mathematically scaled to display in engineering units from -999,999 to +999,999. An analog output scaled to the display and relay outputs are optional.
