Submersible Pressure Transducers

Submersible Pressure Transducer                   Model 3550/3555

Model 3550 Submersible Pressure Transducers are specifically designed to meet the rigorous environments encountered in ground and surface water depth measurement applications. These sensors provide repeatable, precision depth measurements under the most hostile conditions.

These transducers incorporate isolated diaphragm sensors which are specifically designed for use with hostile environments. These sensors utilize a silicon pressure cell that has been fitted into a stainless steel package 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 3550 Pressure Transducers feature high performance internal signal conditioning and accuracy is 0.10% FSO. They are available in both 4 to 20 mA and 0 to 5 Vdc output versions. Cable length must be ordered with the Pressure Transducer as it is factory installed.
