All the physical quantities can be expressed from a pulse sequence, including linear movement and rotation. They can be used to detect sequence like motor driving and speed monitor or fault sequence detection like over-speed, under-speed, blocking , standstill. Programmable relay output is available to switch according with input switching frequency, and an analog input 0 –20 mA or 4 – 20 mA adjustable to desirable range..
Also in these products you will find frequency to current transformers, standstill and slip monitors.
Rotational speed monitors are used to monitor rotating shafts or uniformly pulsating movements.A few of the many areas of application are belt speed monitoring on conveyor systems, under-speed monitoring of mixers, monitoring of vibratory feeders.
The new FR-1 series speed monitor is a fully programmable compact unit designed for the evaluation of pulse frequency, rotational speed, linear speed and machine cycles.
It is designed to accept an external pulse train from a single inductive, capacitive, or photoelectric sensor. It is also possible to use a standard mechanical contact closure as an input. Common applications for the FR-1 include over-speed, under-speed and jam detection. It may also be used for fault monitoring and frequency to current conversion.
Adjustable function parameters include switch point, start up delay, output latching, output window function, scalable analogue output (zero and span), and hysteresis. The display indicates Hz, RPM or the milliamp value at the analogue output.

Standstill monitoring is used for rotational speeds as well as uniform stroke movements, ie agitators, bin feeders, centrifuges, worm screws etc.
Slip monitoring is used wherever two rotational speeds need to be compared. Slip monitors can also be used to monitor the synchronisation of mechanically coupled drive motors to ensure uniform wire speed on cable machines.
with model FS you can monitor slip between two rotational movements or synchronous running between two linear movements, have programmable set value (slip in percentage), combined slip and speed monitor (drive speed), error caused by slip during the start-up phase can be ‘ignored’ using the start-up delay time

|handheld instruments - overview|
| model 460; rpm measuring instrument incl. protective cap, batteries and calibration protocol
model 460 optically measures rpm, e.g. of ventilators and shafts. The measurement spot is displayed on the measurement object with an LED marking. Max./min. values are displayed directly at the press of a button. The backlit display allows the measurement values to be easily read out, even in unfavourable light conditions. Model 460 is very handy, small and easy to operate.
Non-contact measurement of rpm in industry
|Model 465, rpm measuring instrument set: Measuring instrument with SoftCase (protective case) in transport case (plastic), incl. reflectors, batteries and calibration protocol
Using model 465, rpm can be easily measured without contact. Simply attach a reflector to the object to be measured and then point the visible, red light beam at the reflector and measure.
|Model 470, rpm measuring instrument set: Instrument with SoftCase (protective case) in transport case, incl. adapter, probe tip, surface speed disc, reflectors, batteries and calibration protocol
Model 470, the ideal combination of optical and mechanical rpm measurement. An optical measurement becomes a mechanical measurement by simply attaching an adapter for probe tip or surface speed disc.
Model 475, mini stroboscope, incl. rechargeable battery, mains unit
Model 475, quick and convenient. Measurements at inaccessible points are made possible by its practical design and rechargeable battery operation.
