  • SGCD4

    Das SGCD4 ist ein Digitalisierungsmodul für kleine Ströme. Es verfügt über vier am PC schaltbare Empfindlichkeitsbereiche und kann Ströme vom pA-Bereich bis hin zu 30µA einfach und präzise erfassen. Das SGCD4 kann auch ohne messtechnische Vorkenntnisse benutzt werden und ersetzt kostenintensive Picoampere-Meter.

FAQ

This content is only available in English
What is the detector speed?
The detector risetime / falltime is calculated by that formula: tr/f = 2 Pi RC with R = internal resistance of the amplifier and C = capacitance of the photodiode. Example = a typical value of R is 50 Ohm and the C value for a SG01S photodiode is 15 pF. This calculates: with R = internal resistance of the amplifier and C = capacitance of the photodiode tr/f = 2Pi * 50 Ohm * 21 * 10-12 F = 6.59 * 10-9 s = 6.59 ns
What is the saturation of a photodiode?
The saturation current Isat of a photodiode is determined by its open circuit voltage VOC and its serial resistance RS following the formula: Isat = VOC / RS A typical value (SiC photodiode) for VOC is 2.0 V and for RS = 5 Ohm. This calculates: Isat = 2.0 V / 5 Ohm = 0.4 A = 400 mA. The saturation radiant intensity z calculates by the below formula: z = Isat / (S * A) Where S is the radiant sensitivity of a photodiode and A is the active area. A typical value for S is 0.13 A/W and A = 0.06 mm2 (valid for SG01S). This calculates: zsat = 0.4 A / (0.130 A/W * 6 * 10-8 m2 ) = 51.28 MW/m2 = 5.13 kW/cm2

Is your UVC photodiode compliant to DVGW W294 (2006)?
Yes, f1,Z is smaller than 0.25
What is the lowest pressure that the photodiode can withstand?
Our UV photodiodes are hermetically sealed and can be used under vaccum, theoretically down to 0 Pa.
When is a filtered UV photodiode needed?
Our four filtered versions of the UV photodiode lead to a tighter sensitivity range.
What is the power input of a Multiboard?
The current consumption of a Multiboard is between 4 mA and 20 mA, depending on the amount and type of operating voltage (uni / bipolar) as well as the load at the output (multimeter = no load).
