Battery (24 VDC) allows use
in locations without AC power supply. AC sine-wave voltage between
electrodes enables stable detection with no electric corrosion.
Outputs can be set to self-hold at ON or OFF
using special circuits.
Adjustable sensitivity, with an operating
resistance range of 0 to 100 kΩ, allows use for a wide variety of liquids.
Relay contact chattering conventionally
caused by waves eliminated using open collector output, reducing contact
wear.
Meets CE marking and is a UL recognized
component.

Features |
|
Combines DC Power Supply with AC
Sensing Method
AC sine-wave signals are sent to electrodes
using a built-in DC-AC converter, preventing electric corrosion and ensuring safety.
|
|
|
Open Collector
Output
Signals can be used as direct input for a PLC.
PNP output is also possible using the connection method.
|
 |
|
Supports
Multi-channel Sensing
Power supply circuits and
detection circuits are isolated, allowing more than one controller to be
used in the same tank.
|
 |
|
Same Wiring for
Supply and Drainage
Supply control and drainage control can be performed with the same wiring
(short terminals 7 and 8 for supply control). This makes it easy to perform wiring and
confirm connection.

Application Examples |
|
Drainage control
for semiconductor wafer cleaning installation |
|
|
Meet safety
standards by using DC power supply for all devices in a panel
|
|
|
Liquid level
control for waste-heat recovery boilers in co-generation systems
|
|
|
Liquid level
control for solar power generation systems
|
|
|
Liquid level
control for remote regions without AC power supply
|
|
|
Cut cost by using 61F in
situations where ultrasonic/electrostatic capacity level controllers were used because only DC
power supply was available.
