Inductive M12 sensor measures contact-free with 4 nanometer resolution

[Translate to int-en:] 483baumer_passion_for_sensors_logo_650

The resolution of Baumer’s IPRM 12 inductive sensor has been significantly improved. The sensor now measures with a resolution of up to 4 nm, which is to date unmatched in its class.
With this performance, it constitutes the ideal solution for monitoring concentricity and vibration of shafts or high precision measurements of manufacturing tolerances and deflections of shafts, leaf springs or levers.
All of the necessary electronics are integrated within its 90 mm short M12 housing. Compared to measuring systems with external evaluation unit this reduces acquisition costs and guarantees an easy integration into compact machines. At the same time, the sensor is one of the fastest sensors in its class with a measuring speed of 1 mm/s.
The IPRM 12 serves as a contact-free measuring system, which does not leave scratches or pressure points on delicately finished products. With its high performance, the sensor is a compelling alternative to complex measuring systems. The high linearity, as well as temperature stability, allow high precision measurements, a robust metal housing and protection class IP 67 equal high durability.
For various measuring tasks three differently configured sensor versions are available. Depending on the application they are optimized for high resolution and high linearity, high resolution in long-range sensing or an extended measuring range upon a minor temperature drift.

Different Types and Applications Of Totalizing Counters

Totalizers are counters that “total” the number of cycles applied to their inputs. The totalizing function does not provide control outputs or preset limits, although some of our multi-function products have the totalizing capability as well as output and control functions. They may be a mechanical counter, electromechanical counter or an electronic counter, all of which may be resettable or non-resettable.

Mechanical Counters

Mechanical totalizing counters typically use printed wheels or drums to display the count value, and are actuated by an external force on a lever or shaft in a reciprocating or rotating action. Mechanical totalizing counters are very robust in their construction and are often found in severe environments which could destroy other types of counters.

Applicationfabric_machine

A mechanical totalizing counter can be used as a yardage counter for sheet goods, fabric, upholstery, etc. in a factory or commercial setting.

743415-005 Worm Drive is part of the 7234 series and pairs well with 15537-070  Measuring Wheels.

Electromechanical Counters

Electromechanical totalizing counters generally are operated by an electrical pulse from a switch or relay and increment counts as the pulses are applied. Certain models have counting coils designed as “continuous duty” which means that the voltage applied to the counter may be of extended length or continuous without causing damage to the coil. They are typically panel mounted or base mounted and offer a low to mid-range cost solution for numerous applications.

Applicationpinball

An electromechanical totalizing counter can be used to count cycles in a gaming machine.

Typical Veeder-Root Counter

779086-006 is part of the 7790/7791 Series. This series of economical miniature totalizers is available in all popular mounts and operating voltages.

Electronic Counters

Electronic totalizing counters are almost always panel mounted, and generally have a good degree of environmental protection making them suitable for wet, damp, or dusty locations. They may be self-powered by an internal battery or externally powered, and are designed to accept a wide range of count inputs like dry contact closures, voltage pulses, TTL level inputs, and quadrature inputs from incremental encoders. Some models offer scalable inputs, meaning that the number of input pulse can be scaled as they come in to result in a readout of more meaningful units of measurement, often referred to as engineering units.

Application

An electronic totalizing counter can be used as a maintenance or usage counter (for revenue) in a copier machine.

Typical Veeder-Root Counter

C342-0462 is one counter in the C342 Totalizing Counter series. This series provides ultra-compact 1/32 DIN totalizers available with LCD or LED display and AC/DC inputs.
Totalizing counters, in all their various types, are an important component in a myriad of applications. So, choose Veeder-Root totalizing counters for a totally reliable, durable, and accurate solution!
