1830 SERIES: Depth & Level Pressure Sensors
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 measurement element manufactured from micro-machined silicon developed within own Class 100 processing facility. The silicon measurement 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 tank contents measurement, containing the most chemically aggressive media.
Depth Cable
Depth cable moulded directly to the sensor body to give IP68
rating for permanent immersion
The encapsulated surface mount electronics are housed within the titanium body tube.
The body tube is welded to the pressure module offering maximum integrity and reliability
Depth cable vent connected directly to the reference side of the silicon pressure element
Pressure connection with radial inlet holes
Screw-on acetal nose cone provides protection during installation.
Pressure Module Assembly
A high stability micro-machined silicon sensing element is contained within the all titanium pressure module assembly. The sensing element is both electrically and physically isolated from the pressure media.
