Product Specifications

Technical details and manufacturing context for Concentration Sensor

Definition
A critical component of a Decontamination System (Isolator) that continuously monitors and quantifies the concentration level of the sterilizing or decontaminating agent (such as hydrogen peroxide vapor, chlorine dioxide, or peracetic acid) present in the isolator's internal atmosphere during a decontamination cycle. It ensures the process achieves and maintains the required concentration for the specified duration to guarantee effective microbial kill.
Working Principle
Typically operates on principles such as infrared (IR) absorption, electrochemical sensing, or photoionization detection (PID). For common agents like H2O2 vapor, an IR sensor measures the absorption of specific infrared wavelengths by the gas molecules, converting this optical measurement into an electrical signal proportional to the gas concentration.
Common Materials
Stainless Steel (housing), Quartz or Sapphire (optical windows), Silicon (photodetector)
Technical Parameters
  • Measurement range for the target decontaminant (e.g., 0-2000 ppm H2O2). (ppm or mg/L) Per Request
Components / BOM
  • Optical Source/IR Emitter
    Emits infrared light at specific wavelengths absorbed by the target gas.
    Material: Tungsten filament or LED
  • Sample Chamber
    A sealed path where the gas sample interacts with the measurement beam.
    Material: Stainless Steel, PTFE
  • Photodetector
    Detects the intensity of infrared light after passing through the sample gas.
    Material: Silicon, Germanium
  • Signal Processor
    Converts the detector signal into a digital concentration reading using pre-programmed algorithms.
    Material: Printed Circuit Board (PCB) with microcontroller

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Fouling and coating accumulation
Cause: Build-up of process material, scale, or contaminants on sensing surfaces, leading to inaccurate readings due to signal attenuation or reflection interference.
Electronic drift or sensor calibration loss
Cause: Degradation of internal components (e.g., reference electrodes, optical sources, or signal processors) due to temperature fluctuations, aging, or exposure to harsh chemicals, resulting in measurement inaccuracies.
Maintenance Indicators
  • Drifting or unstable readings despite stable process conditions
  • Visible accumulation, discoloration, or damage on the sensor probe or optical window
Engineering Tips
  • Implement regular, gentle cleaning protocols using compatible solvents or mechanical wipers to prevent fouling without damaging sensitive surfaces.
  • Establish a scheduled calibration and verification routine using traceable standards, and monitor environmental conditions (temperature, humidity) to correct for drift proactively.
