How the Pulse Recorder Works

A pulse recorder indicates the number of times an event occurred in a given time interval

Pulse Recorder

(models S-UCC-M006 and S-UCD-M006)

The Pulse Recorder records the number of pulses that happen over a period of time. This device groups together or bins the number of pulses according to the time period they occurred in.

Pulse SampleExample:
If you are monitoring traffic through a door, the Pulse Recorder will log the number of times the door was opened during each interval:

1. The door opened 3 times between 9:30: AM and 9:31 AM

2. The door opened once between 9:47 AM and 9:48 AM

3. The door opened twice between 12:32 PM and 12:33 PM

The Pulse Recorder is most useful when you need the ability to collect rapid pulses that are too fast for the Event or State. It offers a more efficient way to collect information from a source which produces pulses at a constant rate. By binning the data without recording a time-stamp, the Pulse Recorder uses less memory than the Event or State.

Example:
Using the data collected in the above example, you can calculate additional data such as:Pulse Sample

1. The door was opened for a sum of 8 times over the full period.
2. The average number of times the door was opened per minute is twice
3. There is more traffic through the door before 10:00 AM than after 12:00 PM

The Pulse Recorder requires a signal of at least 1ms duration and at least 8.33 ms between the leading edge of each pulse to be counted. If these conditions are met, then every pulse will be logged up to 65535 pulses per time interval.

Conversely, a pulse may not be recorded if it is less than 1ms or if more than one pulse occurs within a 8.33 ms period. If the latter happens, further data points may not be recorded until 8.33 ms after the first pulse.

A common application for the Pulse Recorder is to measure the flow rate or total volume of a pipeline. The Pulse Recorder collects pulses generated by a flow meter and uses that information to calculate the number of gallons per minute. The flow meter produces a pulse that is too rapid to be collected by the Event or State, yet can easily be binned by the Pulse Recorder. The important data here is not the exact time when the pulse took place, but rather the number of pulses in a time interval.
