Description
Series TPSA transmitters are based on fluid-free sensing element on stainless steel diaphragm.
An innovative mechanical structure makes the sensor completely insensitive to tightening during installation.
This transmitter is suitable for all those applications where in addition to ruggedness and reliability high accuracy is required.
