Pressure transducers use hydraulic transmission
Terwin 5000 series transducers and transmitters use hydraulic transmission between the diaphragm that is is contact with the melt and the strain gauge assembly that produces the electrical output.
The 2000 series incorporates unequalled mechanical and electrical design features to overcome the problems of large zero and span shifts caused by changes in process temperatures.
This has only been obtainable in the past with transducers that use a filled system incorporating substances such as mercury or sodium potassium.
All Terwin 2000 series transducers are constructed throughout from stainless steel and do not employ any toxic substances, thus allowing them to be used on machines involved in the process of food, film or pharmaceutical products.
Pressure ranges are available from 0-35 to 0-2000bar.
Other units of pressure measurement such as pounds per square inch and megapascals are available if required.
When it is required to measure temperature and well as pressure, the 2000 series is available with type J or K thermocouples.
