Laureate Series Electronic Counters Panel Meters from Laurel Electronics
The Laureate Series Electronic Counters Panel Meters from Laurel Electronics are modular, high-precision instruments designed for accurate counting, timing, rate measurement, and advanced signal processing in industrial environments. Built on a flexible platform with isolated boards, these Panel Meters offer exceptional customization through plug-in options for setpoint control, analog outputs, and digital interfaces. Their crystal-calibrated time base (±2 ppm accuracy) ensures reliable performance across demanding applications, from basic pulse counting to sophisticated batch control and quadrature positioning. The Panel Meters' compact 1/8 DIN size and rugged construction make them ideal for control panels where space and durability are critical.
Modular Design and Core Advantages
These Panel Meters feature a base configuration including a main module, power supply, and signal conditioner board. Optional boards add dual relays, isolated analog outputs (4-20 mA or 0-10 V), or communication (RS-232, RS-485, Modbus RTU/TCP, Ethernet). All boards are isolated from meter and power grounds for noise immunity and safety. Common specifications across the series include:
- Crystal time base calibrated to ±2 ppm
- Span temperature coefficient ±1 ppm/°C (typical)
- Long-term drift ±5 ppm/year (typical)
- 6-digit LED display with customizable scaling and brightness
- Universal power supply options
Available Electronic Counters Panel Meters Models
The Laureate Series includes eight specialized models for electronic counting and timing applications, each optimized for specific industrial needs:
- Frequency, Rate, or Period Panel Meters
These Panel Meters measure frequency (cycles/second), rate (events/time), or period (time/cycle) with high-resolution timing and exceptional noise rejection. Ideal for monitoring motor speeds, generator frequencies, flow rates from pulse-output meters, or signal periods in test equipment. Custom scaling allows direct display in meaningful units like RPM, GPM, or Hz, supporting applications in machine diagnostics, power monitoring, and process optimization.
- Rate & Totalizer with Mathematical Functions Panel Meters
These Panel Meters combine simultaneous rate display with totalization and powerful arithmetic operations (A+B, A-B, A×B, A/B, A/B-1) on dual inputs. Perfect for combined flow monitoring (e.g., net flow from supply and return lines), efficiency calculations, draw ratios in extrusion, or power measurement from voltage and current signals. The dual-channel capability and math functions provide advanced process insight in a single compact unit.
- Dual-Channel Pulse Input Totalizer Panel Meters
Dual-channel pulse accumulators, these Panel Meters count events from sensors, proximity switches, optical encoders, or flow meters with support for up/down counting and inputs up to 1 MHz. Scalable totals, preset batch counts, and high-speed performance make these Panel Meters ideal for production counting, material handling, conveyor monitoring, and inventory control where accurate accumulation of discrete events is required.
- 6-Digit Analog Input Totalizer & Process Panel Meters
These Panel Meters integrate analog signals (4-20 mA, 0-10 V, or process voltages) over time with optional square root extraction for differential pressure flow applications. They display both instantaneous process value and accumulated total, making them suitable for volume totalization, energy monitoring, or batch integration in flow, level, or pressure systems.
- Batch Controller with Pulse Input Panel Meters
These Panel Meters provide precise batch control using pulse signals from flow meters or counters, with dual relays for start/stop sequencing, pre-warn alerts, and main batch operations. K-factor scaling, overrun compensation, and automatic repeat batching ensure extreme accuracy in filling, dosing, or dispensing applications across chemical, food, beverage, and pharmaceutical production.
- Batch Controller with Analog Input Panel Meters
These Panel Meters offer sophisticated batch control for analog process signals with proportional dosing, dual relay outputs, and overrun compensation. Optimized for automated mixing, filling, or portioning where continuous analog feedback from level, pressure, or flow transmitters is available, delivering consistent batch results even in variable process conditions.
- AC Phase Angle & Power Factor Panel Meters
These specialized Panel Meters measure phase angle between voltage and current along with true power factor in single- or three-phase AC systems. Essential for motor efficiency monitoring, power quality analysis, reactive power compensation, and energy optimization in industrial drives, generators, transformers, and distribution networks.
- Quadrature Encoder Input Panel Meters
Designed for bidirectional position and rate measurement from quadrature encoders, these Panel Meters support high-speed tracking up to 250 kHz with zero-channel index for precise homing. Perfect for motion control, length measurement, positioning feedback in CNC machines, conveyors, and robotic systems.
Common Applications Across the Series
These Panel Meters are widely used in industries requiring accurate counting, timing, or rate monitoring:
- Manufacturing & Production Lines: Count parts, measure cycle times, total output, or control batch processes for efficiency and quality assurance.
- Process Automation & Flow Control: Monitor flow rates, batch volumes, or event totals in chemical, food, pharmaceutical, or water treatment systems.
- Energy & Power Management: Track power factor, phase relationships, or energy pulses in generators, motors, inverters, and distribution networks.
- Motion Control & Robotics: Provide high-speed position feedback and velocity measurement from quadrature encoders in CNC machines, conveyors, and robotic equipment.
- Test & Measurement Labs: Deliver precise timing and counting for experimental setups, equipment validation, and R&D projects.
- Material Handling & Logistics: Accumulate counts or totals for inventory tracking, packaging operations, and weighing systems.
