The product is a pressure transmitter with the following features: pressure range from -5% till +105% FS, adjustable up to 1:4, measuring range of 0 … 50 mbar and 0 … 1000 bar, output signal of 4 . 20 mA, calibration available for all common pressure units mH20, mWs, mWC etc., adjustable delay, reverse polarity and short circuit protected, active temperature compensation (option)
The PTM/EX pressure transmitter is designed for hazardous areas and provides a wide range of pressure measurement options, from 0.05 bar to 1000 bar, with intrinsic safety certifications (ATEX, SEV). It features a piezoresistive measuring element, adjustable output (‑5 % to +105 % FS), and optional active temperature compensation.
Electrical specifications include a 4‑20 mA current‑loop output, supply voltage of 9‑30 V DC, and selectable delay times. The device complies with multiple IEC and EN standards for mechanical robustness, emissions, and immunity, and is available in stainless‑steel or titanium housings with Viton seals.
