Using the catalogueUsing the catalogue

By taking a few minutes to familiarise yourself with how the catalogue is organized, you will find it very easy to use.

This section on "How to use this section" (Page No. 10 and 11) helps you make a logical choice in selecting the best product for a particular application. It allows a user familiar with our product line to locate the exact page the product is listed on. For those not familiar with our products, a logical sequence is given to help the user pick the best product for their need.

By taking a few minutes to familiarise yourself with the catalogue organisation, you will find it very easy to locate the product / information you need.

1. The distinguishing factors of FC and FE switches are given on page 3. It will help for selection of right product for your application.

2. The contents page lists the broad outline in which the catalogue is organised, and will help the user familiar with products to select the page on which the product or other useful information is listed.

3. Need Product Selection help ?

Product selection help will start with the “Pictorial Index” (Page No. 8 and 9) of selected section, where the products are broadly classified. A brief description of each product group , a typical photo of the product within the group and the page number on which it is listed are given.

Catalogue Purpose :

This catalogue is a representative of the Kaustubha Udyog flameproof product line. It presents simplified ordering information on most products and references products not catalogued. This catalogue is intended to familiarise users with the broad product offering and provide ordering information for most popular listings, many available off the shelf from local authorised distributors.


By evaluating and comparing these parameters, a logical selection can be made. Turn to the page on which the product information for the selected product is listed, for :

Capsule Construction details

Physical sizes

Special features

Ranges, hysterisis, electrical ratings etc.

Ordering information

Some applications

In many cases, more than one product may work. For the most cost effective solution, compare prices and consider alternatives. Remember, the end cost includes initial product price, plus the installation, plus the service.

4. Need the terminology explained? (see page 72)

Turn to page 72 for the definitions and terminology. This will help you familiarise with the terms used throughout the catalogue.

5. Need information on Accessories? (see page 71)

Turn to page 71 for information on important accessories. These will give information on only important accessories, and information needed, when these are to be supplied with our products.

6. Need selection guidance? (see page 73)

A logical procedure on page 73 will help you to consider most of the important factors when selecting a pressure switch.

FC Flameproof switches :

These switches have been designed for use in hazardous areas and for severe applications in the Oil and Gas sectors like oil and gas pipelines, petrochemical plants, refineries and generally in atmospheres which are potentially explosive. All switches are designed for gas group IIC, the most severe of the explosive gases, and hence can be used in lower severity atmospheres, typically in IIA and IIB. With grey cast iron enclosures, these can also be used in mines.

SS enclosures can also be offered for highly corrosive atmospheres. Switches can be configured with a lot of options like electrical elements and sensing element configurations to suit the intended working media.

Advantages over FE switches:

Large spring for accurate setpoint

Better accuracy

External scale for visible setpoint

ATEX and IECEx approvals, which makes them usable almost throughout the world.

HOW TO USE this section

Due to the variety in product types and their salient features, catalogue page formats may vary. But generally the following format is adhered to.

Elements appearing on each page will be:

1. Product family / series - A product family / series willappear on the outside page corner, depending on the left / right hand page, and will be in large bold type.

2. Product section - will appear immediately following the product family / series at top of the page and will be in bold type.

3. Pressure capsule details - will show the construction of the pressure capsule and all it's internal parts. If theprocess / working medium is variable, the wetted parts will be mentioned in italics. If the wetted parts are unique, the material of construction (MOC) will be mentioned alongside in brackets. Where the material of construction is not specified, it will vary and the options are to be selected by the user considering the compatibility of the process / working medium. Modifications can be made to

Installation drawing - will show the typical installation dimensions of products as they exist in their standard forms. The dimensions are mentioned in millimetres and also in inches to facilitate the user. The dimensions of accessories will have to be added to these to arrive at any particular general arrangement (GA) drawings. The dimensions are approximate and for precise dimensions, where mounting space is restricted, the user may contact the nearest sales office. Installation drawings of only fast moving accessories are given.Dimensions are approximate and for precise dimensions, where mounting space is restricted, the user may contact the nearest sales office.
