Have a question about something on this blog, a troubleshooting problem you're stuck on, or feedback on an article? I'd like to hear from you.

Email: dashingboy1725@gmail.com

I try to respond to genuine technical questions and feedback where I can, though as this is a personal blog alongside full-time plant work, replies may take a few days.

For quick questions, feel free to leave a comment directly on the relevant post — it also helps other readers who might have the same issue.

Capacitive Level Sensors

Capacitive Type Level Sensors Capacitive type level switches and transmitters are widely used in industrial level measurements. The capacitor is made up of two plates and isolated by some isolators having a fixed dielectric constant. But in level measurement we use a variable capacitor, capacitance can be changed by changing the gap between the two plates or by changing the dielectric constant, so dielectric constant changes and proportional to that capacitance also changes. Capacitive level switches  Capacitive level switches are used in industrial applications for the point-level sensor to detect a high or low level of a vessel or tank. Working principle of capacitive level switch  In capacitance type level switches, there are two main units: 1. Capacitive probe 2. controller  The capacitive probe is made up of two plates mostly in the shape of two rods. and the material we want to sense acts as a gap between the plates.  As material touches, the sensor probe, the...

Radar level measurement

 Radar Level  Radar level transmitter are used to measure level in industrial applications. Radar level measurement method is an advanced method. In radar level transmitter time of flight method is used to measure the level. By calculating this time of flight we measure the level of liquid or solids.  RADAR level have a transmitter which transmit microwave or radar waves after colliding with material they return back to the receiver.  The time from the transmitter to the echo return to the receiver, is calculated, which is proportional to the level. This time is calculated by the formula:  Distance = (Speed of light x time delay) / 2 This calculation is done by a built in microprocessor and the level is displayed on screen or lcd, a signal proportional to level in 4 to 20 mA is output of level transmitter , this standard current signal of 4 to 20 mA is for plc or dcs. Time of Flight technology  Time of flight technology is used in  devices that are mu...

Solenoid operated valve

Solenoid valve A solenoid valve or SOV is an electro mechanically operated valve.  This is controlled by an electric current through a solenoid coil, a magnetic field is produced in the electrical coil which mechanically operates the plunger of the valve and hence changes the path of air or fluid from one direction to another direction. Types of solenoid valve: 2/2-way solenoid valve This type of valve has 2 ports and it acts in  2 positions.  It means the solenoid valve has two ports one is the inlet port and another port is the outlet port, material passing through the solenoid valve either pneumatic or fluid is applied to the inlet port and exhausted through the outlet port. Two-position of solenoid valve means that its piston or plunger has two-position, either valve is open or close. 3/2-way solenoid valve  This type of valve has 3 ports and 2 acting positions. 5/2 way solenoid valve  This type of valve has 5 ports and 2 positions. Types of a solenoid valv...
