The DB Electroprobe is intended for use in the sector of level control instruments, opens up a whole new field of multifunctional equipment.

Application: in the field of level control instruments, it is a multifunctional device.
Advantages: an extremely innovative product which unites a series of
functions in a very small space (4 DIN modules):
– ON-OFF electroprobe (operating in one single point): acts on relay 2 using probes
6 and 12.
– Differential electroprobe (operates between two probes positioned by installer): acts
on relay 1 using probes 10 and 11, always together with 6 and/or 7 as common.
– High alarm: use probes 9 and 6.
– Low alarm: use probes 8 and 7.
– Internal Buzzer: For high and low alarms.
– Control for external alarm (buzzer or light).
Benefits: Possibility of activating or deactivating controls by means of dipswitch. The
installation of 4 electroprobes would be necessary to obtain the same functions.

Application: Level controller by DIN rail mounting.

Advantages: The EV type guarantee the SR type flexibility, the NS type performance
and , moreover, it also allows to:
– set the relay start time delay 0÷16s
– select the filling or emptying function.
– request a relay output with 2 change over contacts in 3 DIN rail version.

Benefits: High tech device with micro controller, beside adjustable sensitivity, permits
to set a relay start delay and has multivoltage power supply version.

Operation principle: sense the condutcion of the liquids with the probes. The deepest probe is the common, the two are the max and min. level switcher. The length of the cable of the probe can be 1000 m. When the 3 probes sink into the liquid, an inner relay activates within the Q2 EV. With the decrease of the liquid level, the device will close the relay.

Q-SR probe level regulators are for liquids with different conductive (from 1 to 100 kΩ). Perfect solution for various industrial liquids (for example.: vine, liquid soap, milk, soda).

Application: Level controller by DIN rail mounting.

Advantages: a wide range for each need.

Models SR [ adjustable sensitivity]
For the control of conductive liquids with unknown conductivity this model is essential
which controls up to 100 Kohm.

Benefits: easy to install and the experience of Mac3 ensures ideal operation for use in
water systems.
