Dead Weight Tester

1. A dead weight tester apparatus uses known traceable weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gauge
2.  A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.
3. Typically deadweight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.

Pressure Tx: Calibration Fuji

Pressure TX: Calibration (Siemens)

How to  Calibrate

Hold M(mode) for 2 to  4 second

again click mode to next setting (Total mode 14)

M5 mode is used for Inital set/zero scale (LDV)

M6 mode is used for span 100%            (UDV)

M7 used for zero adjustment if calibration is out 

(Zero adjust in atmosphere)

2 , 3 wire proximity sensor connection

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.Vibration measurements of rotating shafts in machinery.

• Roller Coaster
• Conveyor System
• Mobile Devices
• Touch Screen that come in close proximity to the face
  
   capacitive sensing is a technology, based on capacitive Coupling, that takes human body Capacitance as input. Capacitive sensors detect anything that is conductive or has a dielectric  different from that of air.
  
  Inductive
  An proximity(inductive) sensor is an electrinic Proximity sensor, which detects metallic objects without touching them

Ohms to Degree Conversion

°C= Total Resistance-100*2.6°C= 109.625-100*2.6= 25.025°C

Degree convert into ohms

 ohms=  °C*.385 +100= 

 ohms=  25°C*.385+100=109.625ohms

linear variable differential transformer

The linear variable differential transformer (LVDT) (also called just a differential transformer,is a type of electrical transormer used for measuring linear displacement (position). A counterpart to this device that is used for measuring rotary displacement is called a rotary variable differential transformer (RVDT).
The linear variable differential transformer has three solenoid coils placed end-to-end around a tube. The center coil is the primary, and the two outer coils are the top and bottom secondaries. A cylindrical ferromagnetic core, attached to the object whose position is to be measured, slides along the axis of the tube. An  A.C drives the primary and causes a voltage to be induced in each secondary proportional to the length of the core linking to the secondary.The frequency is usually in the range 1 to 10 khz.

Why cascade control loop is more preferable in the critical process , and what is an advantage of this loop ?

cascade uses in a criticle & precise controlling,it gives a 

predictive response where ever some possibility of d main 

feed/source disturbance,in this case cascade responds very 

quickly before any interruption in d process.

how to convert Mv to Degree for j and k type thermocouple see

1. for  J type Thermocouple= mv*18.85

for K type Thermocouple=mv*24.5

Example:
mv= 34
fot k type then =24.5*34= 833.c temp:

How to calibrate ultra sonic level transmitter? See

Ultrasonic transducers are transducers that convert ultrasound waves to electrical signals or vice versa. Those that both transmit and receive may also be called ultrasound transceivers; many ultrasound sensors besides being sensors are indeed transceivers because they can bothsense and transmit.

SOV Coil

A solenoid is simply an electromagnet
This is the basic working principles behind a solenoid but instead of picking up metal filings, the magnetism generated is used to move an armature which can do work.
In most appliance solenoids, instead of having a stationary pin (nail in the illustration above) around which the coil of wire is wrapped, the coil is wrapped around a hollow tube. Through the center of this tube a metal armature is installed which is affected by the magnet field produced whenever power is supplied to the coil. This armature can be attached to levers to lock or open a door for example and powered via an electrical switch when needed to activate it.

Magnetic Flow meter

The third most common flowmeter (behind differential pressure and positive displacement flow meters) is the magnetic flow meter, also technically an electromagnetic flow meter or more commonly just called a mag meter. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe surface, for example, a rubber-lined steel tube.

optocoupler

1. In electronics, an opto-isolator, also called anoptocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal.

Schenck Process system Coal Feeding used in Cement Industry

1. The Multicor-K small grained/powdery Coal Feeding System is specially designed for economical.
2.  reliable and environmentally friendly powedry coal feeding for the firing of rotary kilns. 
3. Using highly accurate Coriolis technology,
4.  the Multicor-K system employs a matched Multicell unit,
5.  which features a large inlet section and integrated agitator, providing the optimum solution for stable,
6.  Equally material flow in the prebin.
7.  Because the system is designed to eliminate aeration,
8.  air pockets are minimized reducing the potential for pulsations or unstable conditions.
