PLC UV SENSORS & VIS SENSORS
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. This means that sensors can be optimally adapted to the application. Going further, the sensors are available for special cases and with customer-specific measurement and spectral ranges.
For small control tasks, the PLC sensors can be connected to an RM-32 panel meter. The RM-32 shows the current irradiance on a 3.5-digit digital display and switches two relay contacts with adjustable warning and alarm signals.
To protect the sensor against contamination and aging (at extremely high irradiance and periodic reference measurements) we recommend our shutter.
