These easy to use, intrinsically safe tachometers can display speed in engineering units from a wide variety of pulse output sensors such as a proximity detector or switch contact. To simplify maintenance, the instruments also contain a second display which can simultaneously show the run-time of the monitored machinery. International certification allows worldwide installation.

Accessories, include a display backlight, isolated dual alarms and an isolated 4/20mA output.

Tachometers can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional charge. An optional stainless steel legend plate is also available which can be supplied laser engraved with customer specified tag and application information.

Other tachometers in our range include:
