INSTRUMENTATION LIMITED KOTA

INTRODUCTION

“INSTRUMENTATION LTD, KOTA” is a govt. of India enterprises established in Kota(Raj.) in 1966-67 with the prime objective of attaining self-reliance in the field of contract & automation for the process industry.

The major products that IL presently manufacturing are

(1)Card Assembly (PCB centre)(2)Railways Signaling Relay(3)Gas Analyzer (4)UPS (Engineering, Production, Servicing)(5)Telecom Division

Uninterrupted Power Supply (UPS)

• The basic UPS shall consist of rectifier/charger, inverter, external source of stored power (usually a battery), associated circuitry, protective devices and accessories as required for proper operation.

Types Of UPS

1.Off Line UPS

2.On Line UPS

Off Line UPS

In offline UPS input is directly connected to output.

Inverter is not used in this type of UPS.

Output will be in square form because input is directly connected to output.

Block diagram of Offline UPS

On Line UPS

•Input is connected to load through inverter.

•Output is in sine form.

•Frequency of output is constant.

Application

• Power plants

• Refinery

• Industries using computer-controlled equipment.

RAILWAY SIGNALLING RELAY

RELAY

What is a relay

A relay is a multi switch device with multiple mating contact pairs.

The relay are two contact pairs-1.font contact pairs= front contact pairs are normally open.2.Back contact pairs= The back contact pairs are normally close.

TYPES OF RELAYS:-

I.L manufactures two types of signaling relays.

LINE RELAY

TRACK RELAY

LINE RELAY

• This type of relay is used for classification of line.

• There are two signals Red and Green.

a) Red signal indicates that the line is busy.b) The green signal indicates that line is clear.

TRACK RELAY

• This type of relay is used for changing track at railway station.

Card assembly (PCB Centre)

Types of card assembly

1. Through-hole (TH)

2. Surface Mount Technology (SMT)

Surface mount technology (SMT)

• Electronic components are mounted to the surface of printed circuit board.

• Place the components.• At last Pick and mount machine using .

TELECOM TECHNOLOGY

C-DOT DSS BUILDING MODULES

• This field of telecommunication has evolved from a stage when signs, drum beats and semaphores were used for long distance communication to a stage when electrical-radio & electro-optical signals are used.

Gas Analyser

• Gas Analysers are the instruments used for continues measurement of percentage of a particular gas in a gas mixture.

Following types of Gas Analyses

S.NO. TYPE OF ANALYSER GAS MEASURED

1. Paramagnetic O2

2. Thermal Conductivity H2, So2, CO2, Ar.3. Infrared CO, CO2, SO2, NH3

4. Zirconia probe type Analyser O2
