How to Use Compact Data Loggers
Calculating insolation and evaluating solar panel generating capacity based on actinometer data from a data logger
Input analog voltage output from an actinometer to the LR5041 and record insolation data at an interval of 1 minute. After capturing the recorded data at a regular interval and downloading it to a PC, you can calculate insolation for a given day or a specified period of days by using Excel’s time average or integration functionality. By comparing this insolation data to the solar panel installation’s generating capacity, you can evaluate whether the solar panels are generating electricity normally. The typical actinometer has a minuscule analog output voltage of about 10 mV. Since the LR5041 has a 50.00 mV measurement range, it can reliably record even minuscule voltage variations. In addition, the instrument can operate continuously for more than one year on a single alkaline battery when using a recording interval of 1 minute.
Recording integrated flow rate data from a gas meter or water meter with a pulse logger
The Pulse Logger LR5061 is a pulse logger that can record pulse output as integrated count values from a gas or water meter for extended periods of time. The pulse count is stored for each recording interval in the instrument’s data memory. After downloading the data to a PC, you can convert it to an integrated flow rate by multiplying the measured values by the pulse flow rate coefficient. The instrument can operate continuously for more than six months on a single alkaline battery when using a recording interval of 10 seconds.
Recording 4 to 20 mA instrumentation signals from a sensor or signal converter with a data logger
The Data Logger LR5031 is a data logger for instrumentation signals that can continuously record 4 to 20 mA analog current output from a device such as a signal converter at a set interval. The instrument has a ±30.00 mA range and resolution and can operate continuously for two years on a single alkaline battery when using a recording interval of 1 minute.
Temperature logger that can be used outdoors
The Temperature Logger LR5011 features a dust-proof and waterproof enclosure so that it can be used outdoors with peace of mind, making it ideal for use in applications such as managing the temperature in plastic greenhouses. The instrument can operate continuously for more than two years on a single alkaline battery when using a recording interval of 1 minute.
Testing load power with simple power logging functionality
The Clamp Logger LR5051 can record two channels of AC current data from clamp-on sensors. It can also record average, maximum, and minimum values, allowing calculation of integrated current values from 1-minute average values if data is integrated at a recording interval of 60 sec. In addition, power and energy can be calculated if the voltage value and power factor are set using application software. Consequently, this battery-powered data logger can be used as a simple power logger.
