Product Description
The 520 and 528 series Pressure Transmitters are compact, precise and economical. They have a rapid coupling and installation system (Quickon System), which substantially reduces the signal cable assembly time.
The model 520 is designed for use in industrial and refrigeration applications. It has a welded stainless steel diaphragm allowing its use in any gas or cooling medium, including ammonia.
The model 528 is ideal for industrial applications that require pressure measurement in liquids and gasses. This model uses a ceramic sensor that has a high mechanical stability and is capable of withstanding a wide range of temperatures. It is particularly suitable for applications involving compressors or steam.
