EAF tacho indicator Frequency-Current converter

About the product

The tacho indicators of type EAF ... 5 contain a built-in, directly matched measuring converter that converts the pulse frequency signal from a contactless sensor into a direct current that drives the meter. Any frequency range can be allocated to any indication range within the limits specified in the technical data

The various connection options allow almost all common sensors to be used. The HORNEL heart rate sensors are
particularly suitable as the frequency ranges are essentially defined by their design. The indicators are also available upon special customer request with
an additional current output of 0 to 20 mA, except for types EAF 72x72, EAF 80, EAF 100 and EAF 107. The response threshold for the input signal as well as the display, where necessary, together with the current output, can be adjusted with a small 2 mm screwdriver after removing plastic plugs from the back of the meter.
