The BH25 is a high resolution exposed linear encoder with interferometric measurement signal generation. The BH25 scale has a graduation period of 1µm. The interferometric laser scale principle generates a sinusoidal measurement signal with a signal period of 250nm in the read head. The BH25 is characterized by its small size and high signal quality. It is suitable for resolutions of up to 3.8pm. Due to the reflective scanning and the small design it is perfectly suited for high accuracy X/Y stages with linear motor drive as well as for measurement applications

The BS78 is a high accuracy exposed linera encoder with an interferometric signal generation in transmitted light design. The scale has a graduation period of 0.55µm. The LASERSCALE operating principle generates a sinusoidal measuring signal with a signal period of 138nm. This has an extremely high signal quality with a very low noise component. This allows resolutions of up to 2.1 pm to be generated. Due to the extremely low interpolation error, the BS78 is perfectly suited for ultra precision machining, measurement and calibration applications.

The BL57 is a high-resolution, exposed linear encoder with interferometric operating principle in transmitted light design. The BL57 has a graduation period of 1.6µm and generates a sinusoidal signal period of 400nm due to the laserscale operating principle. This allows resolutions of up to 6.1pm. to be achieved. Due to the high response speed of up to 3m/s, it is perfectly suited for high-precision and fast X/Y stages.

High-precision angle measuring system with +/-0.1s accuracy for measuring and calibration applications. The signal sampling is done by an interferometric operating principle (laserscale) The graduation period is 1µm, the generated signal period of the output signal is 250nm. Scale errors are self-compensated by using six reading heads in a special arrangement. The measured values can be output in csv format via the USB interface. The software for measured value acquisition and storage is included in the scope of delivery.

The BL50H is a high resolution exposed linear encoder in reflective design. The BL50H has a grating period of 1.6µm and generates a signal period of 400nm with the Laserscale operating principle. The extremely small dimensions, made possible by the reflective design and large mounting tolerances, allow easy integration into X/Y stages and a wide variety of measurement applications. It provides a very high signal quality with low noise level and is suitable for resolutions up to 6pm at travel speeds up to 3m/s.

The UV measuring probes with 14 mm diameter only serve as compact, long-term, stable measuring heads for the supervision of UV irradiation systems and for UV measurements in inaccessible locations. In addition, optional water and light guide adapters enable the application in hot locations and in water disinfection systems. The integrated electronics generate a signal voltage that is transferred to the UV monitor RM-31 or to the PLC with low noise by a shielded cable.

The PLC UV sensors and VIS sensors serve as precision sensors for the measurement of UV irradiances and illuminances in systems with programmable logic controllers (PLCs). Spectral range, measuring range, operating voltage, and output signal can be selected to match the measurement task and the PLC. The integrated electronics generate a signal voltage that is transmitted with the low interference cable to the PLC. The built-in diffusers provide the required cosine correction. The sensors are calibrated with traceability to the PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are shipped with a factory calibration certificate. Excellent long-term stability is achieved through the use of appropriate materials. Of course, a repair and spare parts service is available for many years. Our product range includes eight spectral ranges and three measuring ranges for the sensors.

The high-voltage generator DG 206 is used to supply KERSTEN neXt® discharging components. The high-voltage generator DG 206 is supplied by an input voltage of DC 24V ± 20%. An LED displays the operational readiness as well as any feedback relating to a short-circuit error in one of the connected discharging components. The short-circuit error Feedback and a cable rupture detection also takes place via a 24V DC signal. The high-voltage generator offers 2 touch-safe high-voltage connections.
