Vibrometer contain a laser , which on the surface to be measured focus is. Due to the Doppler effect shifts upon movement of the surface to be measured the frequency of the backscattered laser light. This frequency shift is in the vibrometer by means of an interferometer is evaluated and as a voltage signal or digital data stream output. A scanning vibrometer enables field measurement of vibrations. A vibrometer is generally a two beam laser interferometer that measures the frequency (or phase) difference between an internal reference beam and a test beam. The most common type of laser in an LDV is the helium-neon laser[1], although laser diodes[2], fiber lasers, and Nd:YAG lasers are also used. The test beam is directed to the target, and scattered light from the target is collected and interfered with the reference beam on a photodetector, typically aphotodiode. Most commercial vibrometers work in a heterodyne regime by adding a known frequency shift (typically 30–40 MHz) to one of the beams. This frequency shift is usually generated by a Bragg cell, or acousto-optic modulator.

The IEC 61672-1 specifies “three kinds of sound measuring instruments”.[1] They are the “conventional” sound level meter, the integrating-averaging sound level meter, and the integrating sound level meter. The standard sound level meter can be called an exponentially averaging sound level meter as the AC signal from the microphone is converted to DC by a root-mean-square (RMS) circuit and thus it must have a time-constant of integration; today referred to as the time-weighting. Three of these time-weightings have been internationally standardised, ‘S’ (1 s) originally called Slow, ‘F’ (125 ms originally called Fast and ‘I’ (35 ms) originally called Impulse. Their names were changed in the 1980s to be the same in any language. I-time-weighting is no longer in the body of the standard because it has little real correlation with the impulsive character of noise events.

Roller Thrust Bearing used for axial loads, but they are suitable for heavy loads and have high axial capacity. Bearing House offers our clients with a wide range of Roller Thrust Bearing. We also offer Roller Thrust Bearing in customized specifications as per the clients’ requirements.

Radial Load Cylindrical Roller Bearings work in linear contact with the raceways and have high radial load capacity. Bearing House is offering popular brands of quality Radial Load Cylindrical Roller Bearings.

Moreover, the diverse design of our cylindrical roller bearings are changed by the lip arrangement.

Clutch Release Bearings are widely used to gearbox. They are designed for the special purpose to control clutch conditions that are associated with the mis alignment of components. We specially design these clutch pins allow maximum speed and loads. The bearings have a high load carrying capacity and are extremely suitable for bearing arrangements where radial space is less or limited.

Pillow Blocks, the most commonly used type of mounted units, are designed to provide Heavy duty support where the mounting surface is parallel to the shaft axis. The bolt holes are usually slotted for adjustment during mounting. Block bearings are supplied in a variety of configurations. Pressed steel pillow block bearings are also available for light-duty Services.

Specialities : Ruggedly constructed, Optimum strength, Excellent finish.

Bearing House offer to clients with pillow block ball bearings that are widely used in agricultural machinery, conveying equipment, and construction machinery. These comprises deep groove ball bearing sealed on both sides and a spherical outside diameter together with housing, which is either a casting or a sheet metal stamping. In these bearings, the units are supplied as plummer block or flanged housing mountings and the pillow block ball bearings helps in covering the current units for metric and inch size shaft.

A pillow block, also known as a plummer block or bearing housing, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel.

Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact. Thus, these are ideal for compact designed applications. Bearing House provides Needle Bearings sourced from well-known manufacturers which complies with International quality standards having numerous rolling elements with extremely high radial load carrying capacity.

Tachometers or rev counters on cars, aircraft, and other vehicles show the rate of rotation of the engine’s crankshaft, and typically have markings indicating a safe range of rotation speeds. This can assist the driver in selecting appropriate throttle and gear settings for the driving conditions. Prolonged use at high speeds may cause inadequate lubrication, overheating (exceeding capability of the cooling system), exceeding speed capability of sub-parts of the engine (for example spring retracted valves) thus causing excessive wear or permanent damage or failure of engines.

Laser Tachometer is a non-contact instrument designed to sense the presence or absence of a reflective surface in its optical beam. A TTL signal is asserted whenever a reflective surface is placed within its field of view. The signal may be used with a counter or spectrum analyser to sense linear translation, rpm or transient vibrations. Laser Tachometer is designed to meet the needs of the industrial user as well as for laboratory use. The ability to mount the electronics up to several hundred meters from the optical head gives the user sensing capability in harsh environmental conditions. Use of existing display equipment as a readout device provides additional savings to the user.
