Electronic Digital Manometer SA-DPS-310GX combines the functions of a manometer with a digital display and pressure relay. It measures excess and vacuum pressure in the range of -1 to 10 bar, providing pneumo-electrical conversion of indicators and their display on a two-colour LCD. Two discrete transistor outputs NPN and PNP allow pressure control over the upper and lower set limits. This allows integration into a pneumatic system in a SCADA production management system.
The electronic vacuum gauge of the SA-DPS-310GX series can be used independently or in combination with the precision pressure regulator SA-RP.
For additional convenience, the air pressure sensor is equipped with a protective setting lock and a power-saving mode that reduces energy consumption by up to 20%.
The display of the electronic air pressure sensor (digital vacuum gauge) SA-DPS-310GX shows pressure in seven measurement units, including kPa, MPa, bar, kgf/cm², mmHg, inchHg, and psi. The industrial digital manometer has a default external pipe thread of G1/8", but other options (R 1/8", NPT 1/8") and internal M5 are available.
The digital pressure relay can be used as a vacuum switch under negative pressure. Two digital outputs (PNP and NPN), two-colour display (red/green), electrical connection: rear plug connector, cable.
Various mounting options: mounting bracket / panel mounting. The digital vacuum manometer also has a function for copying settings from one sensor to another and a button lock function to prevent unauthorized changes to settings.
