SENSORS

General Description

HydroLynx pressure transducers are specifically designed to meet the rigorous environments encountered in level measurement applications. These transducers provide repeatable, precision depth measurements under the most adverse conditions.

All transducers incorporate isolated diaphragm sensors which are specifically designed for use with hostile fluids and gases. These sensors utilize a silicon pressure cell that has been fitted into a stainless steel housing with an integral, compliant stainless steel barrier diaphragm. This sensor assembly is housed in a rugged 316 SS case which provides for a variety of pressure inputs as well as electrical output connections.

Model 5050LL-PTK pressure transducers feature high performance and internal signal conditioning. They are available in both 4 to 20 mA and 0 to 5 Vdc output versions.
