Description
LR8515 Wireless Logger for Voltage and Temperature Measurement
The LR8515 Wireless Logger is designed to simplify voltage and temperature measurement in environments where traditional wired data loggers are impractical. Compact, lightweight, and wireless, this two-channel logger enables engineers, technicians, and maintenance teams to collect accurate data with minimal setup time.
Supporting both voltage input and thermocouple types K and T, the Logger offers versatility in a single device. It can measure everything from minute voltage signals generated by pyranometers and heat flow sensors to battery voltage and temperature. This makes it a practical choice for applications such as photovoltaic system maintenance, correlation analysis between voltage and temperature, and testing in electronics, automotive, and transportation systems.
Wireless data collection is achieved through built-in Bluetooth technology, allowing measurement data to be downloaded directly to a smartphone, tablet, or PC. Data can be retrieved at any time during recording, and all collected values are automatically merged into a single file. This ensures continuity of data and allows users to review trends, waveforms, and numerical values directly in the field without interrupting measurements.
The device is designed for flexibility in installation. Its compact, pocket-sized body allows placement inside control panels, switchboards, or confined spaces where wiring access is limited. By eliminating the need to route cables outside panels, measurements can be performed safely with panel doors closed. Optional accessories such as magnetic straps make wall mounting quick and simple.
Power flexibility further enhances usability. The logger can operate on two AA alkaline batteries for approximately seven days at a one-second recording interval with Bluetooth enabled. For longer monitoring periods, an AC adapter or external power supply can be used. A built-in power-saving function activates Bluetooth only during predefined intervals, extending battery life while ensuring reliable data storage.
With an internal memory capable of storing 500,000 data points per channel, the LR8515 Wireless Logger ensures dependable long-term data capture. Whether used for maintenance inspections, energy monitoring, or research testing, it delivers reliable wireless measurement in a compact and easy-to-use form.
