Description

Micro Series digital panel meters, counters, timers and serially-driven remote displays are an exceptional value by providing high performance at minimum cost, as made possible by state-of-the-art circuit design and firmware. Modular design and a wide range of plug-in options allow the Micro Series to be configured for a wide range of applications from simple measurement to control and communications as part of a data network.

Micro Series base models, as featured in this web page, provide 0.56″ high red or green LED digits, and are housed in a standard 1/8 DIN size panel-mount case (48 x 96 mm panel cutout). All power and signal connections are via push-in screw-clamp connectors.

Large-Digit models using the same signal conditioning boards, I/O boards, and firmware, are also available for viewing across a plant floor or outdoor yard: 5″ digits (Mighty-5). The Mighty-5 features sunlight-readable, ultra-bright LED digits, plus a NEMA-4X housing which can be installed outdoors in any weather.

The minimum hardware modules of a Micro Series instrument or remote display are a power supply, display subsystem, signal conditioner board, and microcomputer board. Different microcomputers boards are used depending on the application (DPM or counter, standard or extended). Three slots are provided to plug in an optional alarm / setpoint controller board, an analog output board, and a communications board. In combination with firmware and user-programmable selections, these modules provide a rich set of solutions for industrial measurement, display, and control applications:

Micro Series 5-Digit Analog Meters by Application:

• DC Digital Panel Meters:  DC Volts, mV, Amps, mA.
• AC Digital Panel Meters:  True AC rms Volts, mV, Amps, mA.
• Process Meters:  Scalable display for signals such as 0-1 mA, 4-20 mA, 0-10 V.
• Process Signal Totalizers:  Totalizing for 0-1 mA, 4-20 mA or 0-10 V signals.
• Strain Meters & Potentiometer Followers:  Sensitivity to ±200 mV full scale, 4-wire bridge connection.
• Microvolt & Load Cell Meters:  Sensitivity to ±20 mV full scale, 4- or 6-wire bridge connection.
• Weight / Scale Meters:  Special capabilities for weighing applications.
• Temperature Meters:  Multiple thermocouple & RTD types handled by same meter.

Micro Series 6-Digit Serially-Driven Remote Displays:

• Serially Driven 6-Digit Remote Display: RS232 interface for point-to-point communications, or RS485 for up to 31 addressable displays on same data line. Each remote can provide independent setpoint control and an analog output tied to the display.

Micro Series 6-Digit Counters & Timers by Application:

• Frequency & Rate Meter:  Two independent scalable pulse-input channels from 0 Hz to 1 MHz to display frequency, rate, RPM, or flow rate.
• Up/Down Totalizer (pulse input):  Two independent scalable pulse-input channels count up or down to a preset at rates up to 1 MHz. Ideal for turbine flow meters. Scaled rate and total in same instrument.
• A+B, A-B, A*B, A/B, A/B-1 Draw Meter:  Arithmetic functions (+, -, /, x) on dual channels A & B. For example, add or subtract rates from two flow meters for combined scaled flow or volume. Display ratio of flow rates, RPM of rollers, or speed of moving belts.
• Batch Controller (pulse input):  A low-cost controller with up to three relays for repetitive fill operations.
• Batch Controller (analog input):  Same capabilities as pulse-input batch controller, but for 0-1 mA, 4-20 mA or 0-10 V process signals.
• Digital Stopwatch:  Time single-events from 1 µs to 99 hours with a timing resolution to 0.2 µs, or accumulate multiple events to 999,999 hours.
• Time Interval Meter:  Time periodic events from 1 µs to 199.99 s over a programmed gate time up to 199.99 s with a timing resolution to 0.2 µs.
• Phase Angle Meter:  20 updates per second for low frequencies, such as AC line frequency. A resolution of 1º, 0.1º or 0.01º is user-selectable.
• 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.
• Quadrature Meter:  Scalable position or rate from quadrature shaft encoder signals.

Micro & Mighty Series Options:

• Custom curve linearization:  For improved accuracy, extended measurement ranges, and special applications.
• PC-based datalogging:  Allows PC to display and log up to 31 meters on one data line, plus 33 virtual meters with combinations of meter readings.
• Dual setpoint relay option:  8A mechanical relays or opto-isolated solid state relays for control and alarm.
• Analog output option:  0-20 mA plus 10 Vdc analog outputs, isolated, linearized and scaled to display.
• Serial I/O option:  Isolated RS232 or multipoint RS485.
• Low voltage power option:  12-34 Vac or 10-48 Vdc operation off battery power in lieu of standard 95-240 Vac ±10%.
