Vacuum pressure transmitter ATM 1ST

barometricpiezoresistive0-10 V

Description
ATM 1ST is a pressure transmitter designed for industrial pressure measurement across a wide range of applications. Its measurement span (0–50 mbar to 0–1000 bar) and available accuracies (down to 0.05 % FS) make it suitable for both static and dynamic measurements. The piezoresistive sensing technology delivers stable performance; hysteresis and repeatability are better than 0.01 %. The modular design enables extensive customization. Available options include negative ranges for vacuum measurement, barometric measurement, and calibration certificate (COFRAC, COFRAC-equivalent or COFRAC-traceable).
