Applications
Pressure transmitters constructed entirely of stainless steel for use in virtually any industrial application where a robust and reliable sensor is required. The 21Y range has an extremely low temperature error. The breadth of the manufacturing range, its modular design, programmable electronics, and the wide range of products manufactured by Keller allow us to supply large batches specifically designed for a particular application. Depending on the application, we can use mPm, Packard, M12 connectors, or cables of different characteristics or lengths. The Y series is characterized by its high immunity to electromagnetic fields, complying with the CE standard by a factor of 10 in terms of conducted and radiated fields. This series is also highly immune to external voltages between the housing and the electrical connection, which is very important when working with frequency converters. The high insulation voltage (300 V) allows these transducers to be used in very extreme industrial environments.
