![]() T7: 16-bit high-speed ADC ( up to 100k samples/s).Expand to 84 analog inputs with Mux80 add-on.14 Analog Inputs built in (16-24 Bits Depending on Speed & Device Type).If the sample rate was cut in half(1 sample per minute), the recording period would double to 7 days. If it is desired to record 2 samples every minute, the data logger can run for 10,000/2 or 5,000 minutes(about 3.5 days). As an example assume that a given data loggerĬan store 10,000 samples. To determine the duration divide the memoryĬapacity(number of samples the device can record) by the sample rate. The recording duration is dependent on the memory capacity of the data logger and the desired sample rate. How Long Can the Data Logger Record Data? This means that the data will not be lost if the power fails. Most OMEGA data loggers use non-volatile memory for data storage. Will the Data Logger Loose its Data if the Power or Battery Fails? Many OMEGA data loggers feature a battery life as long as ten years. In general the faster the sample rate the The battery life of a data logger depends on a number of parameters including the specific model and sample rate. How Long Does the Battery Powered Logger Last? Most data loggers are battery powered some also offer an option for external power. Of data loggers that can sample in excess of 100 samples per second. Although most data loggers have a maximum data rate of 1 or 2 samples per second, OMEGA offers a number The sample rate depends on the specific model. What is the Maximum Sample Rate for a Data Logger? ![]() No, some data loggers provide an option for real-time display but all OMEGA data loggers collect data independently of the computer. This makes them ideally suited for applications requiringĭo Data Loggers Need to be Connected to a Computer? The computer does not need to be present during the data collection process. Data is normally collected in non-volatile memory for later download Data loggers can collect data independently of a computer. Sample rates are required, however, since they require connection or installation into a computer, the computer must also be present and active whenĬollecting the data. Although this option is available with some recorders, it normallyĪdds significant expense to the recorder price.ĭata acquisition systems offer a great deal of flexibility and are certainly attractive when high Most data loggers collect data which may be directly transferred to a computer. ![]() They offer more flexibility and are available with a greater variety of input types. They are 1)Real-Time Data Acquisition Systems, 2)Chartĭata loggers are normally more economical than chart recorders. Three types of instruments are commonly used for collecting and storing data. Why Choose a Data Logger Over Other Types of Data Collection Instruments? Key Aspects to Consider When choosing a Data Logger OMEGA's OM-CP family support this feature. In some applications it may be desirable to display the data being collected in real time on a computer. Rates of 1 per second and the test must last one hour, the data logger must be able to store 3600 samples(1 sample/sec x 1 hour x 3600 seconds/hour). Therefore when specifying a data logger it is important toĭetermine the sample rate and the sample duration which can be used to calculate the required memory. The higher the data rates the more memory required. This is normally because they store data in In comparison to real time data acquisition systems, data loggers generally have low sample rates. OMEGA's OM-CP family of data loggers are extremely compact and include models for most input types. In those cases the size of the data logger may be a critical selection parameter. In many applications space is a limitation. OMEGA OM-SQ2040 Series is capable of handling multiple inputs. ![]() OMEGA offers a wide range of data loggers for several types of signals, including thermocouple, sound, pH, pressureĪnd many more (see the "Types of Signal" for a list).ĭata Loggers are available in both single and multi-channel designs. Programmable for different types of inputs. Some data loggers are dedicated to a certain input type while others are OMEGA offers data loggers that are compatible with most types of signals. When choosing a data logger the following parameters should be considered. ![]()
