• Unique cable seal system
• Fully temperature compensated

 

Description

The Model 456-15 Pressure Transducer is designed specifically to meet the rigorous environments encountered in many level measurement applications. This transducer provides repeatable, precise depth measurements under the most adverse conditions.

 

It has been designed for installation in Class 1, Division 1, Groups A,B,C and D; Class II, Division 1, Groups E,F and G; Class III, Division 1 hazardous locations, when connected to the appropriate Stahl apparatus.

 

The Model 456-15 features high performance internal signal conditioning. An isolated diaphragm sensor has been incorporated for use with hostile fluids and gases. This sensor uses a silicon pressure cell that is fitted into a stainless steel housing with an integral, compliant stainless steel barrier diaphragm. The sensor assembly is housed in a rugged, compact 316 SS case, which provides for a variety of pressure inputs as well as electrical output connections.
