Keller 222155.0038 PA-21Y Absolute Pressure Transmitter, 16 Bar

The Keller 222155.0038 is a Series 21Y piezoresistive absolute pressure transmitter (part no. 81554.33) in a compact, fully welded stainless steel housing, built for industrial applications, heat pumps, air-conditioning and food industry equipment, with a 0 to 16 bar absolute measuring range.

It uses an insulated and encapsulated piezoresistive sensor with a direct analog signal path, is temperature compensated across -10 to 80 degrees C, and delivers an accuracy of better than 0.5% FS with a total error band of 1.5% FS over the compensated temperature range; long-term stability is better than 0.3% FS per year.
