Rapid Calibrating device (Instameter) is designed and built to serve a dual purpose; that of a continuity tester and a calibrator. On plugging theRapid Calibrating device (Instameter) with the selector in the 'OFF' position, the entire circuit continuity is indicated. Once this has been established the sector is positioned at T1, T2, T3, or T4.

The corresponding calibrated mill volts are fed into the instruts, whereupon the corrective calibration can be carried out. The most versatile feature of this unit is that the signal is injected through the compensating cables, connectors etc. thus, there is full compensation for all possible errors, arising due to the cables etc., themselves.
Instruments, thus calibrated with the help of Rapid Calibrating device (Instameter), reproduce the thermocouple signal with 100% exactitude.

Self-powered :

Instameter is self-contained and is powered by a commonly available 9v battery thereby obviating the limitations of external power supply.

Variety type

For carbon equivalent meters 'CC' or 'CS'
For immersion pyrometry systems 'T-10', 'T-13', 'T18'
For oxygen in steel system '0'

Instameter is a portable handy instrument designed and manufactured by Fykays combining several long sought after features that instrument engineers and technicians desire o have in a rapid checking and calibrating device for use on the shop floor.

THERMOXYTIP contains a well-established solid electrolyte and a solid-state reference material encapsulated in a quartz tube to form the Oxygen sensor in a modular form. This sensor together with the Oxygen activity in the steels form a millivolt cell and generates an e.m.f. Proportional to the amount of dissolved Oxygen in the molten steel bath. 

A high melting point virgin metal rod forms the bath electrode making contact with the molten metal thus completing the electric circuit. The well-known THERMOTIP brand Disposable Thermocouple forms the companion bath temperature sensor. 

Multivarious uses of THERMOXYTIP:

The carbon content in steel can be estimated under certain circumstances. When the Carbon and the Oxygen reaction has reached an equilibrium this may be expressed by the relation:M=(% C) (%O) = 0.0022Thus with an indicated oxygen content of say 300 ppm, the carbon content can be estimated to be 0.073 %.Since Silicon and Oxygen diffuse very rapidly at liquid steel temperature, the equilibrium of the reaction Si + 2 O = SiO2 is achieved very quickly and % Si can be estimated by the equation.Log % Si = 20, 166 E/T - 12530/T + 2.78Where E = Oxy probe output voltsT = Temperature in Degrees KelvinIn case of low carbon Aluminum killed argon stirred steels (LCAK), the residual aluminum can be determined.

Description : FYKAYS' OXYCOMP-D® is a versatile microprocessor based, extremely fast instrument for rapid determination of active oxygen in molten steels and alloy steels as well as copper alloys.

The instrument derives its twin signals of oxygen cell voltage and bath temperature from two-in-one probe - THERMOXYTIP®, instantly calculates and presents a DIRECT Digital display. By virtue of fast sampling techniques (less than 200 mS), unique Plateau detection method, latching and storing of data, the OXYCOMP-D® retains the transient output signals from the expendable probe (Max 10-15 secs) and calculates the oxygen content in the molten metal.

Technical Features :

The instrument architecture is built around the versatile 8085 A microprocessor. Dual 4 ½ digit A/D converters convert the thermocouple and oxy cell mV signals in less than 200 mS. The detection of the steady values is achieved by unique "plateau detection" method. The RAM stored values are fed on to the CPU, which calculates and displays the results on bright, 25 mm, seven LED's.The various equations are stored in battery backed ROM's. In order to facilitate proper operating, the system has built-in audio-visual signaling system, which generates functional signals such asREADYMEASUREMENT IN PROGRESSOVERERROR

It is the Micouple Bow to the Industry's demand/Desire for Quality, Economy and Safety. Mi Couple is supple, Durable and Accurate to the Core. It is designed to be a part of the heating structure. In that process it stands BEATINGS in the beds and TWISTINDS in the walls so that it can keep in touch with the superhot materials and transmit the process temperatures Days in and Years out. Mi Couple represents a wide range of permanent thermocouples to be useful to many industries. Mi Couple is produced by : Fykays Engineering Pvt. Ltd. Leaders in Advanced Pyrometry.

On the lop, at the bottom and the walla throughout the arduous path to the control apparatus. Nil Couple and Micab combination of Thermocouple technology is assiduously developed for superfast and accurate temperature measurement from vital spots considered inaccessible so far, as the high temperatures and hitherto undiscovered materials of construction precluded precise probe. It now facilitates rigid quality control denied thus far to the quality conscious decision makers. While helping to improve quality Mi Couple enables closer control on fuel costs. Its contribution to Industrial Safety is a very important consideration in its favour. 

Mi Couple is embedded at the critical process paint to catch the process temperature and transmit the signal to the control apparatus through Mi Cab. ft thus simplifies and hastens decision making for Quality, Economy and Safety. Whereas Mi Couple describes the Mineral insulated thermocouples, Mi Cab describes the Mineral insulated cables that truthfully complement the relay function of Mi Couple through a little less hostile environment. 

Mi Cab is the most reliable complement to Mi Couple because it shares its superfast signal transmission efficiency and resistance to the varying temperature zones of the traversing regions and also to static interferences through its exposed path. Mi Couple is made available in many versions, to serve varied industries. Whereas, the Nuclear, Aircraft, special steels, Ferro-Alloys and their like attract the Costlier versions; less exacting conditions in Dairies, Power stations, Pharmaceuticals may opt for the economic variety suited to their respective plants & processes. 

Depending on the specifications of each Industrial Process or Product Fykays offer a wide choice for Mi Couple - Mi Cab ingredients.

SCALE LOSSES AND FUEL LOSSES are the biggest causes of concern for all re-heating furnace owners, particularly in these recession–hit times.

Scaling Loss:

On an average, Indian scale loss is 1.5% to 3.5%. However, not many people are aware that the average International scale loss is 0.2% to 0.8%. It is possible to limit scale losses and match international standards. A rough estimate is that a scale loss of 1% in a daily production of 100 MT of rolled steel will cause a loss of Rs.36000/- per day i.e. Rs.108 lacs per annum.

Fuel Loss:

Indian consumption of fuel per MT of steel rolled is anywhere between 38 to 55 litres, which is, again, way above the International average consumption of Furnace oil 25 litres/MT.

A reduction in fuel consumption by even 10% would effect savings of upto Rs. 11700/- per day or approximately Rs. 35 LACS per year (at an average consumption of 45 litres / MT and at a production level of 100 MT per day and taking the cost of Furnace Oil to be approximately Rs. 26/ Litre).

Scale losses and increased fuel consumption are caused mainly due to too much excess air in the furnace due to incorrect air: fuel ratio, causing the excess oxygen to oxidize the job in the re-heating furnace and sensible heat being carried away from the furnace requiring more fuel to be pumped in.
Re-heating plants across India are thus losing lacs and lacs of Rupees every year. What is the solution.

1. "OXYCOMP-G" - FYKAYS ONLINE OXYGEN ANALYSER
The OXYCOMP - G works on the well–proven Zirconia sensor principle which enables detection of Oxygen in the furnace from PPM level to 100%. 
The OXYCOMP-G has been specifically developed to monitor the amount of excess oxygen in the re-heating furnace gases. Once this is known, the user can control the amount of fuel injected. 

For example, if the Oxygen percentage is too high (say 5%), the instrument will give an indication on the remote display and the air injected into the furnace will have to be reduced by the user. This will obviously reduce fuel consumption as well as scaling losses. 
This document is the property of Fykays Engineering Pvt Ltd and may not be reproduced in any form without prior permission. 

The basic components of Fykays OXYCOMP-G system are as follows:

Oxygen Probe: The Zirconia Oxygen probe which senses the Oxygen in the furnace atmosphere
Probe heating Furnace + Controller: A small auxiliary furnace which is installed on the side wall of the re-heating furnace in which the Oxygen probe is installed. This furnace temperature is controlled with the help of a PID controller.
The Oxygen Analyzer
The reference air system
The electronic purging apparatus
The remote display: The signaling panel with Hi/Lo alarm

Once the Oxygen content in the furnace atmosphere is indicated by the instrument, the fuel can be controlled manually. If desired, the output from this system can be used to automate the control of fuel injection into the furnace with the use of control valves. 

2. OXYCOMP G-II FYKAYS OXYGEN ANALYZER AND CONTROLLER

Recognizing the industry requirement for automated control, we developed the OXYCOMP G-II. Essentially, it is also built around the well proven Zirconia technique and enables precise detection and control of Oxygen over a wide range. 

In addition, this version of OXYCOMP G-II utilizes an equally well proven technology namely Variable Frequency Drive (VFD) to regulate the speed of the main air blower so as to reduce the air intake into the furnace so as to contain the excess free Oxygen, instead of having to depend on the furnace fireman.
