Sentry 111 Pulse Summation Counter
The Sentry 111 is designed to be a simple pulse counter/divider to allow testing of internal standards on Vision Metering’s Vesta Test System or any other manufacturers test system. It is capable of taking input pulses from three external standards and output a summation of the three inputs to a single output. This output can then be compared to the output pulses of the Vision Standard inside the Vesta Test System.
The inputs can handle up to 1,400,000 pulses per second on all three inputs representing as little as .0001 Kwh/pulse. The output will max out at 420 pulses per second and represent .1 KWh/pulse.
This device can replace the Radian Research RM-111™ when testing Vision’s Vesta Test System internal standard or any other manufacturers test system using external standards as a reference.
The Sentry 111 uses precision digital counters to count and compare calibration pulses from reference standards and billing meters.
This is a simple device requiring no programming. Easy to install and use right out of the box.
