Pressure Transducers
QPress – QLS-CORE 2100 Series
The QLS-CORE 2100 Series is a compact all-316L-stainless pressure transducer built for everyday industrial monitoring and control. Its fully welded stainless body suits machinery, hydraulics, pumps and pipework, and a single 4–20 mA loop output drops straight into PLC and controller inputs without a separate conditioner. With ranges spanning vacuum to 1000 bar, an M20x1.5 process thread and a fast, stable response, one compact model covers a wide spread of pressure points across a plant. Choose the 2100 for straightforward 4–20 mA loops to 1000 bar; the QLS-CORE 2000 adds voltage outputs and connector options on ranges to 100 bar.

Key Features
- Fully welded all-316L stainless wetted parts suit machinery, hydraulic and pipework media across vacuum to 1000 bar.
- Single 4–20 mA loop output feeds PLC and controller inputs directly, at ±0.5 % FS accuracy.
- Fast ≤1 ms response and ≤±0.1 % FS repeatability give stable readings on dynamic pressure.
- IP65 ingress protection with vibration and shock resistance per IEC 60068 for demanding installations.
- Multiple output options — 4–20 mA, 0–10 V and 0.5–4.5 V ratiometric — simplify integration.
