Component Specifications

Definition
A precision optical component integrated into high-purity sodium nitrite curing salt production equipment that provides real-time visual feedback on chemical concentration levels through calibrated color changes, ensuring consistent product quality and process control in meat curing applications.
Working Principle
Operates on photometric analysis principles where specific wavelengths of light interact with sodium nitrite solutions, causing measurable color variations that correlate directly with concentration levels. The system uses calibrated optical sensors and reference standards to detect subtle hue changes, converting them into concentration readings displayed through LED indicators.
Materials
Food-grade 316L stainless steel housing, borosilicate glass optical windows, PTFE seals, FDA-compliant epoxy coatings, corrosion-resistant sensor elements
Technical Parameters
  • Accuracy ±2% of reading
  • IP Rating IP67
  • Power Supply 24V DC
  • Output Signal 4-20 mA analog / Modbus RTU
  • Response Time <5 seconds
  • Pressure Rating 0-10 bar
  • Measurement Range 0-200 ppm sodium nitrite
  • Calibration Interval 90 days
  • Operating Temperature 0-50°C
Standards
ISO 22000, ISO 9001, DIN 11850, FDA 21 CFR Part 110

Frequently Asked Questions

How often should the color indicator be calibrated?

Calibration is recommended every 90 days using certified sodium nitrite reference solutions to maintain measurement accuracy within ±2%.

Can this indicator detect other curing agents besides sodium nitrite?

No, this specific model is calibrated exclusively for sodium nitrite detection. Different optical configurations would be required for other curing agents like potassium nitrate or sodium nitrate.

What maintenance is required for optimal performance?

Monthly cleaning of optical surfaces with food-grade cleaning solutions, quarterly calibration verification, and annual replacement of O-rings and seals to prevent contamination.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
