High Pressure/ High Temperature Conductivity Sensor SC42/SX42

High Pressure/ High Temperature Conductivity Sensor SC42/SX42

The Yokogawa SC42/SX42 are robust high-pressure and high-temperature sensors for line measurement, specifically designed for applications such as desalination and condensate leak detection. With exceptionally high temperature and pressure ratings, these sensors are ideal for demanding industrial processes.

The SC42/SX42 series is designed to meet the challenges of high pressure and high temperature environments. These contact line sensors offer high accuracy and reliability for measuring conductivity in applications such as boiler blowdown and condensate leakage. The SC42/SX42 series is available in various designs to suit different installation needs, including threaded connections and flanged options for easy integration into existing systems.

Withstanding temperatures up to 250°C and pressures up to 40 bar (depending on model), the SC42/SX42 is optimised for demanding environments where accurate measurement results are essential. High-quality stainless steel materials ensure long life and corrosion resistance, even in aggressive process environments.

The sensor is designed to minimise common problems such as polarisation and contamination, ensuring long-term stability and reduced maintenance requirements. The integrated Pt1000 temperature sensor enables accurate temperature compensated measurements.

Features and benefits

  • High temperature resistance: Withstands temperatures up to 250°C, ideal for applications such as boiler blowing and condensate leaks.
  • High pressure resistance: Flanged models can withstand pressures up to 40 bar, allowing safe operation in high-pressure applications.
  • Flexible installationAvailable with threaded, tri-clamp or flanged connections for different process needs.
  • High quality materials: Made of stainless steel for maximum durability and corrosion resistance.
  • Integrated Pt1000 temperature sensor: Provides accurate temperature-compensated measurements for increased precision.
  • Low maintenance cost: The design reduces problems such as contamination and polarisation, minimising maintenance needs.

Applications

  • Forehead blowing: Precise measurements to optimise system efficiency.
  • Condensate leak detection: Prevent damage and ensure safe operation.
  • Desalination: High performance sensors for environments with aggressive chemicals.
  • Industrial processes: Reliable measurements in high pressure and high temperature processes.
