Digital Panel Meters & Counters
for Frequency, Rate, RPM, Speed

Product Selection Guide
  

Laurel digital panel meters are available to display frequency in Hz or rate in scaled engineering units such as ft/sec, GPM, L/sec or RPM. A universal dual-channel signal conditioner accepts pulse from proximity switches with PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, low-level outputs from turbine flow meters down to 12 mV, and high-level AC line inputs up to 250 Vac. Rate can also be displayed from process signals such as 0-1 mA, 4-20 mA, 0-10 V, from quadrature signals, and from changing resistances in potentiometer follower applications.   

Dual channel digital panel meter for frequency, rate, RPM, speed

   
Laureate Dual Channel Frequency Meter, Model FR
 

Two independent channels display frequencies from 0.005 Hz to 1 MHz. Exceptional fast readings to six-figure accuracy.
AC line frequency may be measured to 50.0000 or 60.0000 Hz in a few line cycles. 1000 Hz signals may be measured to 0.01 Hz resolution at up to 25 readings per second. Also displays period, the inverse of frequency. Optional analog output, relays, and data I/O. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.

Laureate Dual Channel Pulse Rate Meter, Model FR
 

Two independent pulse input channels can be scaled to display rates or totals in engineering units such as GPM, L/sec, ft/sec, or Gallons. Dual-channel signal conditioner accepts inputs from proximity switches with PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, low-level inputs down to 12 mV, and high-level AC line inputs to 250 Vac. Allows square root extraction, custom curve linearization. Dual channels allow addition, subtraction or ratio of rates or totals. Includes isolated transducer excitation supply. Fast read rates with peak hold. Optional analog output, relays, and data I/O. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.

Analog Input Process Meter, Model P
 

Displays rate from conditioned process signals, such as 0-1 mA, 4-20 mA or 0-10 V. Capabilities include zero and span adjustment, square root extraction for differential flow meter signals, custom curve linearization, and high read rate with peak capture. Optional data I/O and relays for alarm or control. Five 0.56" (14.2 mm) high digits, 1/8 DIN case.
Laurel Analog Input Process Meter
   
Analog Input Rate & Totalizing Meter, Model VF
 

Displays rate or total from 0-1 mA, 4-20 mA or 0-10 V analog signals (for example to display watts or kwatt-hours from a power transducer with 0-1 mA analog output). Capabilities include zero and span adjustment, square root extraction for differential flow meter signals, custom curve linearization, and elapsed time based on rate (for example, the time it will take bread to traverse an oven). Optional data I/O and relays for alarm or control. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.

Laureate Quadrature Rate & Position Meter, Model QD
 

Accepts low-level differential or single-ended 5 V logic level quadrature signals from shaft encoders to display scaled rate or scaled position in position in engineering units from -999,999 to +999,999. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.

Laureate Linear Displacement Meter, Model P
 

In linear displacement transducer or potentiometric pot follower applications, the signal from a sliding contact voltage divider is converted to position units such as feet, cm, or mm. Speed is automatically obtained from successive readings. High 1 GOhm input resistance on 2 V scale. Display scaled in engineering units from -99,999 to +99,999. Five 0.56" (14.2 mm) high digits, 1/8 DIN case.
Linear Displacement Meter, Laureate Model P
   
Grand Series Large Digit Frequency Display, Model FR
 

5-digit large-digit displays with a digit height of 2.2" (57 mm), 4.0" (102 mm), 5.7" (144 mm), or 7.9" (200 mm) for long viewing distances. Available for frequency measurement to 10 kHz. Scalable to engineering units. Optional relays and data I/O. Choice of display brightness and cases for indoor or outdoor mounting.
