Description N/A 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. N/A The A103 Tachometers provide high-visibility readout of motor, machine shaft or other RPM, yet are extremely compact in overall size. Its dedicated function design makes installation and operation direct and easy. The A103 series also includes matching indicators for count totalization, elapsed time indication, and rate metering, 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. N/A Excellent performance is coupled with flexibility and small package size

The Dynapar™ MAX®jr Tach family set the standard for low cost industrial rate controllers. Programmable calibration factor and decimal point allow speed to be displayed in units, such as: feet/minute, gallons/ minute, etc. Combining high accuracy measurement with alarm capability, built-in diagnostics, large, bright LED display, simple programming and compact size makes the MAX®jr Tachs a best value.

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. 		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 DC power supply.

Powered by a long-life internal 3 volt battery, the A103 requires no external voltage source to operate. Signal input from a Dynapar™ brand magnetic pickup, also requiring no power connection, creates a complete "powerless" speed measurement system. 		N/A The MAX®jr Tach 1 Rate Indicator/Controller performs the basic rate or speed measurement functions. The MAX®jr Tach 2 provides a choice of operating modes: rate of input A, as in the MAX®jr Tach 1; ratio of two independent inputs A and B; and time interval, which can be the period of A or the elapsed time between inputs A (start) and B (stop).
