INFICON SKY CDG025D-X3 0.1 ... 1000 Torr / mbar process gauge - Manual (Page 10)

10 tina57e1 (2010-01)
Current consumption <500 mA
(max. starting current)
Power consumption
(depending on supply voltage)
≤1 W
Fuse required 2) 1 AT (slow), automatic reset
(Polyfuse)
The gauge is protected against reverse polarity of the supply
voltage.
Electrical connection 15-pin D-Sub, male
Sensor cable
without switching functions
with switching functions
5-pin plus shielding
9-pin plus shielding
Cable length ≤100 m (0.14 mm² conductor)
For longer cables, larger conductor cross-sections are required
(R
cable
≤ 1.0 Ω).
Grounding concept
Vacuum flange - signal common → "Electrical Connection"
Supply common - signal common conducted separately; for dif-
ferential measurement (10 Ω)
