Bubbling system EPS-NE
This module is utilised when extreme reliability is demanded; the EPS-NE bubbling system injects air bubbles into the medium it senses simultaneously and continuously the level of extremely dirty or chemically aggressive water and waste water.
The pneumatic level sensor EPS converts air pressure generated by the hydrostatic backpressure of the water level into a proportional, standard electrical signal.
It is possible to correct the zero point and scaling using a single button. False settings and system errors are indicated via LEDs.
The compressor is operated alternately in a duty cycle of approx. 20 %.
The bubble tube can be utilised in potentially explosive atmospheres.
A separate bubble tube and measurement lead arrangement is used to prevent condensation forming.
EPS-NE-S: a test program automatically tests the performance of the compressor daily.
A fault alarm is issued if performance characteristics deviate.
