RADIOMETRIC SENSORS: Reliable measurement of UV irradiance

The UV inline sensor FLT is a compact, and precise measuring system for irradiance measurements in UV facilities, as packaging systems disinfection systems systems for surface activation UV curing systems Aging & test chambers The system consists of a compact inline sensor for fixed installation or use with radiometer RMD / RM-12. Reference measurements are simple and precise due to indentical shape of both sensor versions. Our product range includes eight spectral ranges and four measuring ranges for the sensors. This allows the radiometric sensors to be optimally adapted for the application. The sensors are calibrated with traceability to PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are supplied with a factory calibration certificate. The RMD is characterized by a very high resolution, a high measuring range, a data interface and the illuminated graphic display.

The industrial spectroradiometer iSR900 is an autonomous and high-resolution measuring system for fast and precise measurements in the UV, visible spectral range and IR. The spectroradiometer consists of an array spectrometer without moving parts and a silicon detector with 2048 pixels. The spectral resolution is 0.44 nm. The iSR900 is combined with an SMA-905 quartz light guide and our radiometric measuring heads for irradiance and illuminance measurement. The iSR900 is factory calibrated to PTB. A DAkkS test in our accredited laboratory is optionally available. The iSR900 thus allows accurate spectroradiometric measurements for the evaluation of irradiance and illuminance. The low-scatter design achieves high sensitivity in the UV range. Control and data evaluation take place in the iSR900 so that only a USB or RS485 / RS232 interface is required for the evaluation. With trigger input and output the iSR900 is ideal for automated measurements.

The PLC.D sensors are ready-to-install UV sensors with digital output. This enables reliable and repeatable irradiance measurements in UV systems. Due to the compact design and the eight spectral ranges, the sensors can be used for a wide range of applications, e.g. in packaging facilities sterilisation surface activation systems UV curing systems ageing tests and many other applications With the integrated 24-bit ADCs, the PLC.D sensors close the gap between industrial manufacturing and high-precision laboratory equipment. Measurements can be carried out in a simple yet safe way. RS-485 and USB are available as optional connections for this purpose. The data evaluation takes place directly in the PLC.D sensors, the measured values are protected against transmission errors by a CRC-16 check sums.

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.
