About us

GRUENEWALD manufactures intrinsically safe measuring equipment „Made in Germany“ for underground mining use and is renowned for its standard of high quality and continuous development in the field of control and measuring instruments. Constantly involved in providing tailored solutions for customers, the range is constantly evolving and small quantity orders to suit bespoke applications are available.

The devices can be specified with a luminescent display and customer specific cabling, connections and measuring ranges. IECEx approved they are suitable to be used in hazardous areas including on underground mining systems in QLD and NSW. Likewise the range of flowmeters, pressure transducers, differential pressure transducers, temperature sensors, level transducers as well as combinations of them are all proven in Australian underground conditions.

These robust, high quality instruments provide reliable data in the most arduous of environments at a price below most of the competition.
