PREMASGARD 8148-ModbusMaintenance-free microprocessor-controlled PREMASGARD® 814x - Modbus (Series) with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, connection nozzles for pressure hose (Ø 6 mm), plastic sinter filter (exchangeable), optionally with/ without display, to exactly detect the relative humidity (0…100% RH) and the temperature (–35...+80 °C) in ducts and to measure the differential pressure (max. ± 7000 Pa) in air. International system of units SI (default) can be switched to Imperial (via Modbus). Incl. mounting flange and connection set ASD-06 (2 m connecting hose, two pressure port nipples, screws).
