The 1830 Series is the latest generation of fully submersible sensors which incorporate the most recent technical advances in depth & level measurement.

At the heart of the 1830 Series is a high stability pressure sensing element manufactured from micromachined silicon developed within Druck’s own class 100 processing facility. The silicon sensing element is fully isolated from the media by a titanium isolation diaphragm. The use of titanium enables the sensors to be used in the most hostile of fluids where materials such as stainless steel cannot be considered.

Surface mount electronics within the all-titanium body tube assembly enables minimum sensor size with improved reliability. The purpose designed vented electrical cable results in a depth and level sensor with the highest integrity and the lowest cost of ownership.

With a choice of millivolt or current outputs, small physical size and wide range of pressures, the 1830 Series can be used in a variety of applications from the smallest diameter bore holes to canals, rivers and reservoirs. They are ideally suited fro depth/level application in the oceanographic and remediation industries. The 1830 Series depth sensing transmitters are backed by Druck’s 5-year corrosion warranty.
