The ATM.1ST is an electronically compensated pressure transmitter providing a 2-wire, 4-20mA analog output. The transmitter offers accuracies of ≤ 0.05%FS or ≤ 0.1%FS including linearity, hysteresis, repeatability, zero and span setting errors.
Pressure measuring range: 50 mbar … 1000 bar, Accuracy: ≤ ± 0.10 / 0.05 % FS, Operating temperature: -40 … 125°C, rocess temperature: -40 … 150°C
The ATM.ST/N/T series is part of a comprehensive range of transmitters specifically designed for the long term monitoring of ground water, wastewater and tank level measurement.
Economical transmitters of the L Series are primarily optimized for ambient room conditions and are very well suited to help control energy costs in HVAC and building automation applications.
