This range of tachometers can display speed in engineering units from almost any pulse output sensor such as a proximity detector. To simplify maintenance they can also display the run-time of the monitored machinery. Parameters are easy to adjust on-site and models are available for installation in most safe and hazardous areas. Instruments can be supplied ready to install with customer specified configuration, scale and tag marking.
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 for field mount models.

These easy to use, nonincendive and Ex nA and Ex tc certified tachometers can display speed in engineering units from a wide variety of pulse output
sensors such as a proximity detector or switch contact.It can be installed in Class I, Division 2 and Class II, Division 2, Zone 2 or 22 without the need for
Zener barriers or galvanic isolators thus significantly reducing cost. International certification allows use worldwide.
To simplify maintenance, the instruments also contain a second display which can simultaneously show the run-time of the monitored machinery.
Accessories, include a display backlight, isolated dual alarms and/or isolated synchronous pulse output and/or isolated 4/20mA output.
The instrument can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional
charge. Specified tag or application infromation can also be printed onto the rear of the instrument. An optional Stainless Steel legend plate is also
available which can be supplied laser engraved with customer specified tag and application information for field mount models.

These easy to use, general purpose tachometers can process and display the total number of pulses received and their rate in the same or different
engineering units from a wide variety of 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.
Accessories, include a display backlight, isolated dual alarms and/or isolated synchronous pulse output and/or isolated 4/20mA output.
