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
Totalizer (pulse input)
-
Two independent scalable pulse-input channels. Count up or down to a preset at rated up to 1 MHz. Scaled rate and total from the same electronic counter. Scaling for direct readout in engineering units, such as gallons or cubic feet based on counts from a turbine flow meter. One channel can display total while other displays rate.

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 Totalizer (analog input)
-
Displays and totalizes 0-1 mA, 4-20 mA, or 0-10 V process signals. Square root extraction is standard for flow applications, allowing display of volume from the 4-20 mA signal of a flow transducer with a linear or squared output.

Remote & Large Digit Displays
-
Remote and Large Digit Displays, as defined in this web page, are numeric displays that are driven by a serial signal from a computer, programmable controller, or other instrument. Digit heights can range from 0.56" (14.2 mm) to 11.0" (280 mm). Laureate remote displays, with a digit height of 0.56", are similar to a digital panel meter or counter in appearance.

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.

Product
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
Laureate Time Interval Meter
Model FRI
-
Configured to time periodic events which produce start and stop pulses from 1 s to 199.99 s over a programmed gate time up to 199.99 s. Timing resolution to 0.2 s. Optional data I/O and relays for alarm or control. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.
-
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.

Product
Scale / Weight Meter
-
Equipped with a DC or load cell signal conditioner, this Laureate offers special firmware for scale / weighing applications: two tare functions; count by 1, 2, 5, 10, 20, 50 or 100; auto-zero function; setpoint offset, and dummy right-hand zero for display to 999,990. Built-in excitation for up to four 350-ohm load cells in parallel.

Product
Model QLS 4-20 mA Loop Splitter / Retransmitter
-
Generates up to four individually grounded and individually adjustable 4-20 mA loops from a single 4-20 mA or 0-10V input. Overcomes problems which occur when the same 4-20 mA signal is applied to multiple loads in series. Allows outputs to have different grounds, and allows individual loops to be opened without affecting signal to other loads.
-
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.
-
Product
Digital Stopwatch
-
Designed to time single events or processes which produce start and stop pulses. Resolution to 0.2 s, duration from 1 s to 999,999 hours. Time may be displayed in HH.MM.SS clock format with 1 s resolution or in decimal H, M or S format with six-digit resolution. Multiple events can also be accumulated.
-
Product
Linearizing Panel Meter
-
All capabilities of the Laureate process meter, plus custom curve linearization. Setup is easy using an external PC and linearizing software furnished by Laurel. For example, display liquid volume in irregularly shaped tanks, use with non-linear transducers, or extend the working range of nominally linear transducers.
-
Product
Duty Cycle Meter
-
Displays ON or OFF period as a percentage of total period over a programmed gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is user-selectable. Applications include monitoring modulated proportional control systems and pulse-modulated systems, such as radar, lasers or packet radio.
