Tachometers expand options for gathering machine data

18 February, 2021

SKF has announced three handheld tachometers designed to monitor rotational and linear speeds of machinery, and to help maintenance staff spot any emerging mechanical problems. Data gathered by the three devices can give insights into machine and component health, helping to cut maintenance costs and boost efficiency.

Two of the devices are digital tachometers, while the third is mechanical. All are compact, have large displays, can be operated using one hand, and are supplied with contact adaptors.

• The 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 several measurement modes, uses standard or rechargeable batteries, and has a large LCD screen.

• The TKRT 31 is a more advanced model that measures distances as well as rotational and linear speeds. A large colour screen shows the measured values clearly. The laser-based TKRT 31 and TKRT 21 both allow easy measurement in locations where straight-line access is difficult.

• The TKRT 25M mechanical tachometer uses precise contact measurement to determine rotational and linear speed of equipment such as shafts, conveyor belts and engines. It doesn’t need any batteries and has a large, easy-to-read dial display.

“Our condition monitoring equipment helps plant workers reduce the chance of catastrophic failure and help to minimise maintenance costs,” says SKF’s instrument products development manager, Sylvain Humbert. “It also helps them to order parts in advance, schedule maintenance procedures and plan other repairs during downtime.”
