Portable data logger offers fast wireless sampling

Available from MDL Technologies, readings from sensor modules can be logged at sampling rates of up to 1ms with the new portable data loggers from HIOKI. The LR8450-01 Memory HiLogger can host up to 11 plug-in and wireless modules to record 330 channels simultaneously.

A variety of sensor modules is offered for measuring voltage, humidity, temperature, resistance and strain. Since the loggers can take modules having different sampling speeds, it is possible, for example, to monitor fast variations in voltage at the same time as tracking slow temperature changes.

Each sensor module includes its own A/D converter, assuring a high maximum sampling rate even when multiple modules are added. The strain modules all have a built-in bridge box which allows strain gauges to be directly connected, despite their compact size.

"The LR8450 series is also ideal for capturing output data from sensors that measure low frequency data below 100Hz such as resin pressure or vibration, which are difficult to measure at conventional sampling speeds," said MDL managing director Mark Lucock.

Typical applications for the new loggers are the automotive, construction, agriculture and manufacturing sectors, as well as in preventive maintenance systems.
