Pressure Transducers
QPress – QLS-CORE 2000 Series
The QLS-CORE 2000 Series is a compact universal pressure transmitter built around a digital-compensation core for stable, repeatable readings. A 316L wetted section measures ranges to 100 bar, and a wide choice of analogue outputs - 4–20 mA, 0-10 V or 0.5–4.5 V - plus several process and electrical connectors lets one model standardise across compressors, hydraulic and pneumatic equipment and HVAC. An IP65 housing and EMC compliance keep it dependable on busy plant. Choose the 2000 when you need output and connector flexibility on ranges to 100 bar; the QLS-CORE 2100 takes similar duties to 1000 bar on a single 4–20 mA loop.
