Component Specifications

Definition
A sensor element or probe is the primary detection component within a flow sensor that directly interacts with the fluid medium to measure flow rate, velocity, or volume. It converts physical flow parameters into electrical signals through various transduction mechanisms, enabling real-time monitoring and control in industrial systems.
Working Principle
Operates based on electromagnetic induction (Faraday's Law), ultrasonic time-of-flight, thermal dispersion (heat transfer), or differential pressure (Bernoulli's principle) to detect fluid flow characteristics without moving parts in most designs.
Materials
316L stainless steel housing, PTFE/PFA lining, ceramic or polyurethane sensing surfaces, gold-plated electrodes, epoxy encapsulation, with IP67/IP68 protection ratings.
Technical Parameters
  • Accuracy ±0.5% of reading
  • Flow Range 0.1-10 m/s
  • Output Signal 4-20 mA, 0-10 V, pulse/frequency
  • Response Time <100 ms
  • Pressure Rating Up to 16 bar
  • Temperature Range -20°C to 85°C
  • Process Connection G½, NPT ½, Tri-clamp
Standards
ISO 4064, ISO 6817, DIN EN 1434, DIN 19200
