The ATM.1ST is an electronically compensated pressure transmitter providing a 2-wire, 4-20 mA analog output. The transmitter offers accuracies of ≤ 0.05% FS or ≤ 0.1% FS including linearity, hysteresis, repeatability, zero and span setting errors. Modular construction and more than 30 year proven history of STS piezoresistive sensor technology provide manufacturing flexibility and offers fast delivery for all pressure ranges.
Examples of applications include:
• Test and measurement
• Industrial process monitoring and control
• Test benches and calibration
• Automotive and engine test
