UV-Cosine FAQ

How can I mount the sensor in an outdoor measuring box?

The sensor is supplied with three nuts and two sealing rings. This allows the sensor to be mounted waterproof from the inside looking out of a measurement box.

What torque can I use to tighten the nuts above the UV-Cosine thread?

The nuts should only be tightened hand-tight. The thread of the UV-Cosine is made of PTFE. Excessive torque can damage the thread and cold flow can occur if the pressure is too high.

UV Sensors FAQ

Is the sensor calibrated?

No, the sensor is not calibrated. If required, the sglux calibration laboratory offers an individual calibration service including a calibration certificate. This document assigns the voltage output or the current value of one specific sensor to the irradiation of a specific UV radiation source. As-delivered the sensor is sensitive in the specified range. Please find further details at the sglux website’s calibration section.

What must be observed with regard to EMC stability when installing a probe?

All sglux sensors are supplied with shielded cables. The shield must be earthed by the user on the measuring device side. On the sensor side, the shield is not connected to the sensor housing in order to avoid ground loops in the event of contact with a system housing with a different potential than the measuring device.

Which sensors can be used as a submersible sensors?

All our PTFE sensors (UV-Cosine, UV-Water-PTFE and UV-Radial) are generally suitable for this purpose and are supplied with a special cable gland.

What types of stainless steel are used for the sensors?

Our standard stainless steel is 1.4404, but we can also manufacture our sensors in other steel grades on request.

Which sensors can also be used to measure at higher temperatures (85-170°C)?

All stainless steel sensors can also be used at higher temperatures. These must then be configured with a photocurrent output, which is connected to an external amplifier such as the RADIKON_simple.

What about the time constant of a UV sensor?

By default our sensors do have a large time constant because most applications measure slowly changing signals. The time constant depends on the sensitivity of the device and ranges between 50ms and 200ms. For detection of Xenon flash light or pantograph arc detection according to EN 50317 we produce special solutions with application adapted time constants. If for other applications a shorter time constant than 50 ms … 200 ms is needed we are happy to produce a customized version. Time constant reduction is possible down to 100 µs depending on the irradiance level of the application (gain value).

Do you offer UV sensors for outdoor measurements?

We offer our UV-Cosine sensor for outdoor measurements. The housing is waterproof IP68 at window side, stain repellent and on request submersible.
