Modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Our analog modems are used for transmitting analog signals by any means from driven diodes to radio.

A relay is an electrical switch that opens and closes under the control of another electrical circuit. In the original form, the switch is operated by an electromagnet to open or close one or many sets of contacts to control a high-voltage circuit with a low-voltage signal, as in some types of modems or audio amplifiers.

Relays are used to :

• Control a high-current circuit with a low-current signal, as in the starter solenoid of an automobile
• Detect and isolate faults on transmission and distribution lines by opening and closing circuit breakers (protection relays)
• Perform logic functions
• Perform time delay functions

A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic or photovoltaic that converts one type of energy or physical attribute to another for various purposes including measurement or information transfer.
 
Transducer are of two types :

• Sensor : which are used to detect a parameter in one form and report it in another
• Audio loudspeaker : which converts electrical voltage variations representing music or speech, to mechanical cone vibration and hence vibrates air molecules creating acoustical energy

We supply high quality industrial fasteners like nuts and bolts which are supplied for industrial usage to our clients everywhere. Made from high grade metals these fasteners are durable and dimensionally accurate providing high performance to any device using them. We stock fasteners in a variety of dimensions and sizes and supply them as per requirements of our customers.

A gear is a component within a transmission device that transmits rotational force to another gear or device. It is a round wheel which has linkages that mesh with other gear teeth, allowing force to be fully transferred without slippage. Depending on their construction and arrangement, geared devices can transmit forces at different speeds, torques or in a different direction, from the power source. Gears are a very useful simple machine. A gear is most important feature is that gears of unequal sizes can be combined to produce a mechanical advantage, so that the rotational speed and torque of the second gear are different from that of the first.

A valve is a device that regulates the flow of materials (gases, fluidized solids, slurries, or liquids) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but usually considered separately. Valves are used in a variety of applications including industrial, military, commercial, residential, and transportation. Oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing would constitute the majority of valves used by industry.

A gasket is a mechanical seal that fills the space between two objects, generally to prevent leakage between the two objects while under compression. Mechanical gaskets are economical as they allow less precise mating surfaces on machine parts which can use a gasket to fill irregularities. Gaskets are commonly produced by cutting from sheet materials, such as gasket paper, rubber, silicone, metal, cork, felt, Neoprene, fiberglass or plastic polymer. Our gaskets are made from materials that are compressible to tightly fill the space designed for, including any slight irregularities.

We supply three types of moisture analyzers and all of them provide fast and accurate values for moisture content, percent solids and dry weight analysis of a wide range of products and materials. Moisture analyzers are widely used in research, manufacturing and quality control applications to determine moisture content in a simple and reliable manner. A moisture analyzers providing accurate data on the moisture content and presents it as a percentage of initial mass or of the residual dry mass.

We supply pressure gauges to various industries as they are used in a multitude of ways in the manufacturing and other processes. Pressure gauges and switches are among the most often used instruments in a plant. Low maintenance and consequently reliability can be compromised affecting the safety of the plant if a plant is operated with a failed pressure switch. Our process instrumentation design installs fewer but more useful and more reliable pressure gauges and switches.

Tooth sprockets have teeth like projections arranged on a wheel rim to engage the links of a chain like the chain of a bicycle is mounted on a sprocket. These sprockets are used for many different power transmission and conveyor systems. Mainly made of cast iron, sintered metal and carbon steel. These sprockets are designed to reduce noise and are economic and reliable drive system especially for long running, continuous drive applications that require maximum absorption of shock with minimum torque loads.

Vibration monitoring instruments are used for measuring, displaying and analyzing vibration. These instruments comprise a transducer, data acquisition and either a local display or some sort of output to a computer or another instrument. Vibration instruments can have many features, including features such as totalizing, local or remote display and data recording. They may be stationary or else portable field-type instruments. They can accept a number of different types of transducers, including acceleration, linear velocity, proximity and displacement, rotary velocity and temperature.
