Easy-Installation
One-piece unit is easily installed through a single
3/4-inch, probe dependent vessel opening.
Calibration is quick and simple.

Z-tron IV™ Point Level Switch, a reliable
low-cost, on/off level switch

Z4-Series
Economical
Effective, low-cost material level detection in
a wide variety of applications, and a desirable
alternative to electromechanical level switches.
No expendable parts to buy and stock. No
expensive, extra-cost options.

Maintenance-Free
Unlike paddle wheels, vibrating tines or other
mechanical instruments, there are no components
to jam, break or wear out. No need for routine
maintenance, cleaning or replacing of worn parts.

The low-cost, Drexelbrook Z-tron IV level switch
is unaffected by sticky coatings and impervious to
corrosive liquids. The all-electronic design means
no moving parts to wear, break or fail. Based
on field-proven RF technology, the Z-tron IV is a
simple and reliable on/off level switch.
The compact one-piece unit is inserted through
a standard 3/4-inch , probe dependent, NPT
opening into the vessel so that the sensing
element is positioned at the desired high or low
level. (Other connection types and sizes are
also available.) When the material level reaches
a predetermined point on the sensing element, it
causes a change in status at the electronic unit,
resulting in actuation of the DPDT relay. The relay
can be used to operate alarms, annunciators,
valves, or other control or indication devices.

Reliable Operation
Cote-Shield™ circuitry allows the Z-tron IV
to ignore coatings or build up on the sensing
element. There are no false signals from dust or
tunneling.

Drexelbrook's Exclusive Cote-ShieldTM
Cote-Shield enables the Z-tron IV to ignore dust
pileups, coatings, and sticky buildups on the
sensing element.
