AC Power Line Monitoring

Digital Panel Meters for AC Line Monitoring: AC RMS Voltmeter, AC RMS Ammeter, AC Line Frequency Meter
Accurately monitor AC or true RMS voltage or current, AC line frequency, or phase angle. Options include analog outputs, relay outputs, and serial communications.

Process Signal Display & Control

Digital Process Meter Connected to 4-20 mA Current Loop Process Signal
Accurately display readings in scaled engineering units such as PSI, GPM, L/sec, or LBS from process transducers whose output may be a DC signal such as 4-20 mA or 0-10 V, a pulsed / AC signal, or a changing resistance. Capabilities include custom curve linearization, square root extraction, rate from successive readings, and totalizing from rate signals. Transducer excitation output is standard on most models. Analog outputs, relay outputs, and data I/O options add functionality.

Flow Rate, Flow Total, Batch Control

Dual Channel Rate Meter and Flow Meter for Flow Rate, Flow Total and Batch Control
Accurately display flow rate or flow volume from flow transducers with a pulse or analog output. Read out flow or total to 5 or 6 digits in engineering units such as Gallons, GPM, or L/sec. Available features include square root extraction and custom curve linearization.

Weight, Force, Stress, Tensile Strength

Digital Panel Meter for Weight, Force, Tensile Strength
The transducers may be strain gauge elements which require bridge excitation, zero and span adjustment, high sensitivity, and multiple noise filtering modes. The transducers may also output a conditioned 4-20 mA or 0-10 V signal, which can be accepted by a Laurel process meter. Meter capabilities include high read rate to 60/sec, peak hold, custom curve linearization, and rate from successive readings. Analog outputs, relay outputs, and data I/O options add functionality.
  • Load cell meter.  Powers up to four 350-ohm bridges in parallel in 4 or 6-wire connection. Five-digit display, sensitivity to ±20 mV full scale.
  • Strain meter.  Powers up to four 350-ohm bridges in parallel in 4-wire connection. Five-digit display, sensitivity to ±200 mV full scale.
  • Process meter.  Five-digit display for conditioned signals such as 0-1 mA, 4-20 mA or 0-10 V.
  • Scale / weight meter.  Special firmware for weighing applications. Features include display to 999,990, auto-zero, auto-tare or manual tare, and display toggle between gross or net weight.
  • Large digit displays.  For strain gauges and load cells. Digit heights 2.2" (57 mm) to 7.9" (200 mm).

Frequency, Rate, RPM, Speed

Digital Counter & Tachometer for Frequency, Rate, RPM, Speed
Display frequency, rate or RPM to six figure accuracy based on pulse signals at exceptionally fast update rates. Display rates to 0.01% accuracy based on an analog signal or a changing resistance. Features include square root extraction and custom curve linearization.

Temperature Measurement & Control

Temperature meter by Laurel Electronics
  • Thermocouple Temperature Meter. High accuracy for seven thermocouple types (J, K, T, E, N, S, R), each in one range. User-selectable thermocouple type, °C or °F, and 1° or 0° resolution. Wide range of options for communication and temperature control. Shipped ready to run.
  • RTD Temperature Meter. Exceptional accuracy for Pt100 100-ohm platinum RTDs (DIN or ANSI alpha), Ni120 nickel and Cu10 copper. User selectable RTD type, unit of measure (°F or °C) resolution (1°, 0.1° or 0.01°), and 2, 3 or 4-wire hookup to eliminate lead resistance effects. Wide range of options for communication and temperature control. Shipped ready to run.

Resistance Measurement

5-digit ohm meter
  • Ohmmeter with five jumper selectable resistance ranges from 20Ω to 200 KΩ. Also available with a fixed 2 MΩ range. Accuracy is an exceptional ±0.01% of full scale ± 2 counts. Resolution is one part in 20,000. In the 20Ω range, resolution is 1 mΩ, making the meter suitable for contact resistance and conductance measurements. Custom curve linearization makes this meter ideal for use with thermistors and other sensors whose output is a chaning resistance.

Pulse Counting, Digital or Analog Totalizing

Industrial pulse counting
Count discrete pulses, totalize pulse signals scaled to engineering units (e.g., volume in gallons from a turbine flow meter), or totalize analog process signals. Count up to a setpoint or down from a setpoint. Display rate or total using the same meter. With two pulse inputs, add or subtract two totals, or take the ratio of two totals.

Timing from Microseconds to Hours

Linearizing Digital Panel Meter and Electronic Counter / Totalizer
Time single events in stopwatch mode, periodic events in time interval mode, duty cycle in percent, or time of day.
  • Stopwatch meter. For single events from less than 1 µs to 999,999 hours. Timing resolution to 0.2 µs.
  • Time interval meter.  For periodic events from 1 µs to 199.99 s. Timing resolution to 0.2 µs.
  • Duty cycle meter.  Displays ON or OFF period as a percentage of total period.
  • Large digit timers and clocks.  Display in MM:SS, HH:MM, or HH:MM:SS.Digit with digit heights from 2.2" (57 mm) to 7.9" (200 mm).
