The A103 Programmable Rate Meters are extremely compact indicators providing high-visibility readout of virtually any rate: gallons/minute, feet/minute, parts/hour, etc. Easy to program input-scaling, decimal point, and "dummy-zero" features assure maximum flexibility for any application. The A103 series also includes matching indicators for count totalization, elapsed time indication, simple speed display (RPM) as well as models with a preset output for control by count or time. All are in a uniform 36 x 72 millimeters bezel size package, enhancing your control panel with a family of devices that look and program alike.

Features

N/A

  • Matching totalizing and preset counters, elapsed time indicators, preset timers, and advanced feature rate indicators look great together on a panel
  • High visibility 4-digit LCD display with programmable decimal point and "dummy zero". Backlighting capability standard
  • Input scale multiplier (0.001 to 9999) calibrates input signal to correct engineering unit
  • Long life 3 Volt lithium battery eliminates the need for external power
  • Magnetic input accepts signals from inexpensive, non-powered sensors
  • Option modules provide additional functionality and added convenience - fast, easy installation
  • NEMA 4X/IP65 rated front panel for use in washdown environments The A103 indicators are further enhanced by a series of quick-attach option modules. These can provide a power supply for sensors and display backlighting, and accept high or low voltage AC or DC input signals.

Additional Information

N/A A supertwist LCD display with thick 12 mm (0.47") high digits allows for easy viewing at a glance and feature display-backlight capability by simply connecting an external 12VDC supply.

Powered by a long-life internal 3 volt battery, the A103 requires no external voltage source to operate. A complete non-powered rate measurement system can be achieved by using signal input from a Dynapar™ brand magnetic pickup.
