Industrial Tachos are a.c mains operated types with LED dispalys.
They are readily programmable which enables the displays to be set to indicate for each individual application.
More Information ..

Vehicle tachos are operated from 12/24 Vd.c supplies & use LCD displays.
They are available as panel mounting types or in IP65 water resistant enclosures etc.
They are normally pre programmed for individual applications.

Where it is possible or desirable to use sensors, inputs from voltage or current signals can be used.
The programmable process panel meters enables digital displays to be provided in this type of situation.

IN series tubular proximity sensors operate by sensing the presence or absence of metal targets.
The sensing distances that can be achieved are related to the sensor diameter & the type of metal which is being sensed.
Mild steel gives the greatest sensing distances & large diameter sensors have greater sensing distances than small ones.
IN series sensors can be either shielded(threaded along the complete length) or unsheilded(threaded along part of the length & having a protruding moulding at the sensing end) Unsheilded sensors can have greater sensing distances than sheilded sensors.
Proximity switches should be selected to ensure that the sensing distance is less than the height of the target from any background metal, otherwise the sensor will switch on permantly.
The metal target to be sensed can affect the normal sensing distance as follows,
Mild steel x 1, Aluminum Foil x 0.9, Brass x 0.5, Copper x 0.4, Cast iron x 1.1, Stainless steel x 0.7, Aluminum x 0.45.

Photoelectic sensors may be used where sensing distances greater than 20mm are required.
For tachometer applications they usually take the form of a single sensor working in conjuntion with a reflector or a piece of tape.
