Diaphragm rupture sensor Standard: 30 V DC/ 1A, volt-free contact (closed in normal condition).
(for TZMb)
For safety reasons, the application of a separated extra-low voltage is required
(SELV in accordance with EN 60335-1).
Cable assignment: any
Intrinsically safe option: observe the enclosed operating instructions of the sensor
(EX pump only)!
5 – 25 V DC, in accordance with Namur and DIN 19234, volt-free arrangement.
Nominal voltage: 8 V DC (R
i
~ 1 kΩ)
Current consumption:
active surface clear > 3 mA
active surface covered < 1 mA
Nominal contact spacing: 1,5 mm
The evaluation / supply device must be able to evaluate the changes in current in order to
indicate a diaphragm rupture.
