QPress – QOM-AUTO 3100 Series
Built for rough mobile duty, the QOM-AUTO 3100 Series is a compact 17-4PH-stainless OEM pressure transducer rated for heavy vibration and shock. It covers 0-10 to 0–700 bar with a 4–20 mA output and standard G1/4 or 1/4 NPT threads, so it integrates into automotive, hydraulic and machinery systems without adaptation. The hardened stainless construction and sealed housing keep readings stable on engines, pumps and powered equipment where lighter sensors struggle. Choose the 3100 for high-vibration mobile equipment to 700 bar; the QOM-AUTO 2100 suits lighter vehicle and test-bench duties to 100 bar.
