Modbus or Laurel ASCII ProtocolSerial Output DIN Rail Transmitters
-
Laureate TM Series serial output transmitters can be jumpered for two signal levels: RS232 or RS485. Two serial protocols are selectable in software: Modbus or Laurel's Custom ASCII.Modbus protocol operation is fully compliant with the Modbus Over Serial Line Specification V1.0 (2002) for 2-wire, half-duplex connection.

Datalogging Software
XLog Datalogging Softwre
-
Laurel's data logging software can turn a PC connected to up to Laureate instruments into a powerful, data logging system. The Laureates can be any mix of digital panel meters, counters, timers and transmitters. The software allows 31 hardware instruments and 33 virtual instruments. The latter can display calculated parameters which combine data from multiple instruments.

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
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.
-
Product
Load Cell & Microvolt Meter
-
A high-sensitivity 5-digit meter for use with load cells, strain gauges and microvolt input signals where high accuracy and stability are required. Load cell operation allows 4- or 6-wire hookup and display in engineering units, such as lbs, kg or psi. Built-in excitation for up to four 350-ohm load cells in parallel.
-
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.

Digital Panel Meter
DC
-
Laureate DC voltage and current panel meters with a DC signal conditioner board combine high accuracy with high read rate and a wide range of isolated output options for computer interface and control. Accuracy is 99.99% of full scale 1 count. Used as a direct-reading DC voltmeter, the Laureate provides a full-scale readout of 20,000 counts and six full-scale voltage ranges from 200.00 mV with 10 mV resolution to 600.0 V with 100 mV resolution.

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
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.

Loop-Powered Digital Panel Meter
88-PRO
-
The 88-PRO Process Meter may be connected directly to a 4-20 mA, 10-50 mA or 1-5 mA current loop, with no need for additional power to the meter. This is because the meter is powered directly by the current loop, developing a maximum voltage drop of 2.5 V.
-
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.

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
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.
