New tachometers expand condition monitoring options

Home Engineering Electronic - Instrumentation & Control New tachometers expand condition monitoring options

THREE new handheld tachometers, including an all-mechanical model, have been added to SKF’s portfolio of basic condition monitoring equipment.

These devices monitor conditions such as rotational and linear speed to help maintenance staff spot emerging mechanical problems in rotating machinery.

“Our condition monitoring equipment helps plant workers reduce the chance of catastrophic failure and help to minimise maintenance costs,” said Sylvain Humbert, Product Development Manager for Instruments at SKF.

“It also helps them to order parts in advance, schedule maintenance procedures and plan other repairs during downtime.”

Two of the devices, the TKRT 21 and TKRT 31, are digital tachometers, while the TKRT 25M is mechanical. All are compact, have large displays, and can be operated with one hand.

TKRT 21 uses laser or contact measurement to determine rotational and linear speeds. This allows fast, easy measurement at a safe distance from machinery. The instrument offers high speed and distance versatility in several measurement modes.

The TKRT 21 is supplied with a basic set of contact adaptors, works with standard or rechargeable batteries and has a large LCD screen.

TKRT 31 is a more advanced tachometer that measures rotational and linear speeds, as well as distances. It is supplied with a full set of contact adaptors. A large colour TFT screen displays measured values clearly for the user.

Both the TKRT 31 and TKRT 21 allow easy measurement in areas where straight-line access is difficult by using a laser

The TKRT 25M mechanical tachometer uses precise contact measurement to determine rotational and linear speed of equipment such as engines, shafts and conveyor belts. It requires no batteries and has a large, easy-to-read dial gauge display. The TKRT 25M is supplied with a full set of contact adaptors.

Humbert said data gathered by these tachometers can give a deeper insight into machine and component health, which can help reduce maintenance costs and increase efficiency and profitability. For instance, replacement parts can be ordered in advance, rather than waiting until they have failed.
