It is expressed in <strong>Hertz (Hz)<\/strong> or <strong>Samples per second (S\/s)<\/strong> specified.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The total sampling rate is an important measure of a measurement system's performance, as it indicates the total number of measurement values that can be processed and stored per unit of time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does \"sum sampling rate\" mean?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In a multi-channel measurement system, the available measurement capacity is distributed among all activated channels. The total sampling rate is calculated as the sum of all channel samples within one second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a measurement system can provide a total sampling rate of 10,000 samples per second. This measurement capacity is then distributed among the active channels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At a sampling rate of:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>10,000 S\/s<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following configurations may be possible:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 channel at 10,000 samples per second<\/li>\n\n\n\n<li>10 channels, each at 1,000 samples per second<\/li>\n\n\n\n<li>100 channels, each at 100 samples per second<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The actual available single-channel sampling rate depends on the system architecture and the number of channels active at the same time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Difference Between Channel Sampling Rate and Total Sampling Rate<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These terms are often confused, but they describe different characteristics of a measurement system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Channel sampling rate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The channel sampling rate indicates how often a single measurement channel is sampled per second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong><br>A temperature channel is measured 100 times per second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2192 Channel sampling rate = 100 Hz<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Total sampling rate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The total sampling rate describes the total number of measurements taken by all active channels per second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>20 channels<\/li>\n\n\n\n<li>100 measurements per second each<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2192 Summing sampling rate = 2,000 S\/s<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It therefore serves as a measure of the measurement system's overall processing performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Significance in Measurement Technology<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The sum sampling rate is particularly important in the following cases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dynamic Measurements<\/li>\n\n\n\n<li>Test benches<\/li>\n\n\n\n<li>Vibration measurements<\/li>\n\n\n\n<li>Transient Recordings<\/li>\n\n\n\n<li>Multichannel measurement systems<\/li>\n\n\n\n<li>Energy Analyses<\/li>\n\n\n\n<li>Process monitoring<\/li>\n\n\n\n<li>Research and development<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The higher the sampling rate, the more measurement values can be recorded simultaneously. This enables the synchronous monitoring of many measurement variables and the precise analysis of fast-moving processes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Relation to the measurement time<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When configuring a measurement system in practice, it is often not the total sampling rate that is the decisive factor, but rather the <strong>Measurement time<\/strong> or the sampling rate of a single channel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The measurement time is equal to the reciprocal of the sampling rate:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Measurement time = 1 \/ sampling rate<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 Hz = 1 second of measurement time<\/li>\n\n\n\n<li>10 Hz = 100 ms measurement time<\/li>\n\n\n\n<li>100 Hz = 10 ms measurement time<\/li>\n\n\n\n<li>1,000 Hz = 1 ms measurement time<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This makes it possible to specify exactly how often measurements should be taken.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summing Sampling Rate in Delphin Measurement Systems<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The measurement data acquisition systems from <strong>Delphin Technology<\/strong> support a wide range of requirements, from slow, long-term recording to high-resolution transient data acquisition. Depending on the application, numerous channels can be operated in parallel, and measurement data can be precisely acquired, processed, and stored.

Based on this, the measurement system manages the available total sampling rate and allocates resources to the active channels. This allows for the efficient operation of both a small number of channels at high speeds and a large number of channels at lower sampling rates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Impact on Data Collection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A sufficiently high total sampling rate ensures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Comprehensive data collection<\/li>\n\n\n\n<li>High temporal resolution<\/li>\n\n\n\n<li>Synchronous Multichannel Measurements<\/li>\n\n\n\n<li>Reliable Event Logging<\/li>\n\n\n\n<li>Accurate Trend Analyses<\/li>\n\n\n\n<li>Reliable Process Monitoring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing the right sampling rate always depends on the dynamics of the processes being measured and the requirements of the specific application.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Typical areas of application<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Quality Control<\/li>\n\n\n\n<li>Vibration analysis<\/li>\n\n\n\n<li>Test Bench Technology<\/li>\n\n\n\n<li>Machine monitoring<\/li>\n\n\n\n<li>Process Automation<\/li>\n\n\n\n<li>Energy Monitoring<\/li>\n\n\n\n<li>Temperature Measurements<\/li>\n\n\n\n<li>Laboratory automation<\/li>\n\n\n\n<li>Condition Monitoring<\/li>\n\n\n\n<li>Research and development<\/li>\n<\/ul>","protected":false},"featured_media":0,"template":"","class_list":["post-7413","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/7413","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar"}],"about":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/types\/glossar"}],"wp:attachment":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/media?parent=7413"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
