The MAXIMAT V C, compact overfill sensor, is used as an overfill monitoring device for permanently installed containers used for
the storage of non-flammable, water endangering liquids.
It is equipped with three different output circuits:
• A binary output for controlling a coupling relay or the digital input at a PLC
• A 0 to 20 mA current output for controlling an analog input channel, e.g. a programmed logic controller (PLC)
• Self-monitoring measuring circuit in combination with the MAXIMAT SHR C... measuring transducer with a 2 wires connection.

Note that stored liquids may not tend to deposit and to stick on. The minimal specific weight is 0.7 kg/L.
Designed for oils, emulsified solutions and for non-conductive liquids.

The maximum allowable fill-level of any given tank can be
determined, for example, in accordance with TrbF 280 no. 2.2.
Triggering level A is then calculated in accordance with attachment
1, or the approval guidelines for overfill inhibitors (ZG-ÜS).
Dribbling quantities and switching delay times must be taken into
consideration. Switching delay time can be adjusted at the
MAXIMAT SHR C measuring transducer within a range of 0.3
to 3 seconds.
Installation length L determines the fill-level monitor’s triggering
point. Dimensions are calculated as follows:
H = tank height
A = triggering level
B = connector
E = immersion depth, table E
S = triggering point
L = H - A + B + E + 3
S = L - E – 3
Guide tubes included with MAXIMAT V .3L and MAXIMAT V .4L
adjustable level monitors are supplied 50 mm longer than dimension
L, so that the fill-level monitor can be adapted to correspond to
triggering level A during installation. It is thus possible to readjust
dimension L. After the triggering point has been set, the locking
screws are tightened and sealed against tampering. Due to the fact
that this seal is not removed during periodic testing, dimension L is
always fixed, i.e. no readjustment is necessary
