The Ex-Tacho 10 Intrinsically Safe TachometerFor accurate and fast measurement of shaft rotation or speedThe Intrinsically Safe Tachometer Ex-Tacho 10 is ideal for fast laser-accurate measurement of the revolution of a shaft (either with or without contact) and speed (utilising the special adapter) in Zone 1. The simple 3 push-button operation and the large clearly-readable display with over-head facility enables a wide, flexible field of application.
This lightweight device provides an easy one handed operation and facilitates the carrying-out of measurements after which it can be stowed away in the tool box or jacket pocket. Applications are to be found in the process-control field for the contactless measurement of the revolutions of a shaft at a safe distance using a laser beam. For boiler mixers, the rotor speed can be read-off from the drive shaft at a safe distance and documented. Motor revolutions can be acquired contactlessly in the immediate vicinity without having to open or remove safety fittings such as covers or protective grills. The duration of pulses or the intervals between them can be simply, easily and accurately ascertained. The transport speed of conveyor belts can be exactly measured using the add-on adapter and thus directly recorded in the documentation.
With the Ex-Tacho 10, data can be simply acquired within Ex-protected areas without having to switch machines off because laser-accurate measurements can be made at a safe distance through protective devices thus complying with safety regulations.
