~ 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.

Diaphragm rupture sensor
(TZMb only) Standard: 30 V DC/ 1A, volt-free contact (closed in normal condition).
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)!
