Hall Effect Sensor Working Principle Animation
A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current…
Use of Temperature Transmitters instead of Direct Wiring
For temperature measurements, two ways have traditionally been employed to get process readings back to a monitoring and control system. The two ways are One method  is to use sensor…
Impeller Flow Sensor Working Principle and Animation
Impeller Flow Sensor have magnets which actuate Hall effect switches to detect impeller rotation and this is proportional to flow rate.

How is Pressure Drop Calculated through a Valve ?
The pressure drop across a valve is related to the flow rate passing through it, i.e. the greater the flow rate the higher the pressure drop and the lower the…
