Keller PR-21Y Relative Pressure Transmitter, 10 Bar, 0-5V Output

The Keller PR-21Y (part no. 81554.33) is a Series 21Y piezoresistive relative pressure transmitter with a 0 to 10 bar measuring range and a 0 to 5V analog output, built in the same compact, fully welded stainless steel housing as the 21Y family.

It shares the Series 21Y platform's insulated and encapsulated piezoresistive sensor, temperature compensation across -10 to 80 degrees C, accuracy better than 0.5% FS, and total error band of 1.5% FS over the compensated range; the attached documentation is KELLER's general operating instructions manual covering this and other KELLER pressure transmitter series, since no model-specific datasheet was supplied.
