Previously so called “data-loggers” have been required to do additional tasks such multiplexing and A/D conversion. To reduce the cost/instrument of this technology, designers enable several instruments to be logged at a single data-logger, adding still further to the complexity, size and cost of the device. With complexity comes the requirement for configuration (both hardwire and software) and associated training. The result is an expensive, complex and bulky solution completely unsuited to mining deployment.

SLUG changes the Rules

All that changes with the SLUG. This is possible because all YieldPoint sensors transmit digital signals that require the minimum processing prior to writing into FLASH memory.   Due to it’s simple design, incredibly small size and very low cost, each SLUG is dedicated to a single instrument. With this comes complete versatility, flexibility and simplicity: if a specific sensor needs to be monitored, SLUG can be deployed in a few seconds. No configuration is required since YieldPoint’s digital sensors inform SLUG of critical information such as their SensorID, SensorType and the number of channels -  just ‘plug & SLUG’. Also, by minimizing the cost of a individual data-logger, high risk deployment close to blasts  is viable and lead-wire (the most vulnerable part of any sensor) length can be minimized. If the SLUG is destroyed during deployment, the replacement will cost probably less than 10% of a typical datalogger.
