Description

The Series 20SX is a compact pressure transmitter head with threaded connection designed for OEM integration. Combining the proven 20S transducer element with X‑Line electronics, the Series 20SX delivers very high long‑term stability, high overload resistance and microcontroller‑based compensation of temperature dependence and non‑linearity for maximum accuracy. The compact stainless steel housing simplifies installation in demanding OEM environments.

Key features
  • Very high long‑term stability
  • High overload resistance
  • Microcontroller‑based compensation of temperature dependence and non‑linearity for maximum accuracy and narrow Total Error Band (TEB)
  • Compact stainless steel housing for flexible OEM integration


Technical specifications
  • Pressure ranges: 0…0.3 to 0…1000 bar
  • Accuracy: ± 0.05 %FS
  • Total Error Band (TEB): ± 0.1 %FS @ -10…80 °C
  • Interfaces / outputs: RS485, 4…20 mA, 0…10 V
  • Dimensions: HEX22 x 79.2…119 mm
  • Electronics: X‑Line electronics with microcontroller‑based mathematical compensation


Applications
  • OEM integration for hydraulic and pneumatic systems
  • Test & measurement and calibration benches
  • Industrial machinery and process control
  • Mobile hydraulics and off‑road equipment
  • Laboratory and R&D applications requiring compact, high‑accuracy sensors
