Digital Panel Meters & Counters for Frequency, Rate, RPM, Speed
 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 as0-1 mA, 4-20 mA, 0-10 V, from quadrature signals, and from changing resistances in potentiometer follower applications. |
Laureate Dual Channel Frequency & 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
This process metercan be jumpered for 4-20 mA, 0-10V and other DC signal ranges to display scaled readings in engineering units, such as units of flow or speedd. Capabilities include zero and span adjustment, square root extraction from differential flow meter signals, custom curve linearization, and elapsed time based on rate, such as the time it will take to fill a tank at the current flow rate. Optional data I/O and relays for alarm or control. Five 0.56" (14.2 mm) high digits, 1/8 DIN case.
Analog Input Totalizer & Rate Meter, Model VF
Displays totals or rates from 0-1 mA, 4-20 mA or 0-10 V analog signals, for example to display totaized volume from the 4-20 mA ouptut of a flow rate meter. Capabilities include zero and span adjustment, square root extraction for differential flow meter signals, and custom curve linearization. Totals are reset be applying a contact closed to a control input. Optional data I/O and relays for alarm or control. Optional analog output, relays and data I/O. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.
Laureate Quadrature Rate & Position Meter, Model QD
Accepts the A & B quadrature signals from shaft encoders or linear encoders to provide a highly accurate, scaled, bidirectional display of position, length, or angle in engineering units, such as ft, cm or degrees. The meter totalizes the counts and scales the total in software for display and control. The Extended version of this meter can also display rate, for example to display the speed of a moving slab in ft/sec. Optional analog output, relays and data I/O. Six 0.56" (14.2 mm) high digits, 1/8 DIN case.
MAGNA Large Digit Displays for Rate or Total
Available with 4 or 6 digits and a digit height of 2.2" (57 mm), 4" (102 mm), 6" (144 mm), or8" (200 mm) for long viewing distances. Available for frequency and rate inputs 50 kHz. Scalable to engineering units. Optional dual 5A relays, analog output, and serial data output. Choice of display brightness and cases for indoor or outdoor mounting. Four or six digits. Optional analog output, relays and data output.
