ATM.1ST pressure transmitter features a compact and robust 316L stainless steel housing, as well as a variety of measurement ranges (0…50 mbar to 0…1000 bar) for a wide range of applications. It also offers calibration for all common pressure units, reverse polarity and short-circuit protection, high EMV stability, and a modular assembly for customized versions.
The STS ATM.1ST pressure transmitter is offered in a compact stainless‑steel or optional titanium housing with a piezoresistive measuring element. It provides a wide measuring range from 0 … 50 mbar up to 0 … 1000 bar and is suitable for machine installations, environmental monitoring, food industry, mobile hydraulics and test‑calibration systems.
Key features include reverse‑polarity and short‑circuit protection, high EMV stability, response time under 1 ms, and various ATEX and IP certifications. The device supports multiple pressure units, modular assembly for customized versions, and offers several electrical output options (4‑20 mA, 0‑5 V, 0‑10 V).
