Industry Highlights/AlpHa's Take
Analog vs Digital Sensors: Comparisons and Selection Criteria
Choosing between analog and digital sensors goes beyond tradition or preference; it requires understanding how each technology supports accuracy, integration, and long-term performance. This article compares both sensor types and offers practical guidance to help engineers, operators, and system designers select the best fit for their application.
NTU in Turbidity: What It Means and Why It Matters
NTU remains the most trusted and widely used metric for understanding turbidity and assessing changes in water clarity. Modern optical sensors make NTU measurement more reliable, giving water professionals clearer insight into treatment performance, environmental conditions, and compliance.
NTC vs RTD: Choosing the Right Temperature Sensor
NTC thermistors and RTDs are the most widely used temperature sensors, yet they perform very differently as temperature changes. Understanding their strengths, limitations, and ideal applications is key to selecting the right sensor for accurate, stable, and long-term temperature measurement.
