Merits by introductionof the system

Level sensors born from innovative idea
We introduced a capacitance type measurement
method and realized multi point control by
one unit although one point control by one
unit was the common knowledge.
And we also enabled stepless control by one unit.

Simple structure and easy adjustment
Our level gauges are simple in structure and easy toadjust and can be installed anywhere.

The type of pipe, length, output type(contact point or linear),and installation location can be selected to flexibly meet various
user needs.

Usable with most types of liquids

We would like to offer various options and plan the
product suitable for a wide range of operating conditions.

The performance is less affected by waves, foams, and suspended solids.
(We suggest ways of resolving all problems.)

When the insulator is sandwiched between two electrodes,
the capacitor is formed between electrodes.
We apply this principle of capacitor to manufacture
our level gauges.
Our level gauges use the central conductor and themetal pipe instead of two electrodes.
When the liquid enters the pipe, the capacity of thecapacitor (so-called capacitance) changes in proportion
to the liquid level.
The amount of the change can be converted electricallyand be used as an output signal.

Principle of operation

Easy handling
Upper and lower limits can be easily set and stepless adjustment is possible.
Amplifier section is built into head. （AT・HT・KT・STB）

Easy control
Output terminal can be directly connected to sequencer and relay circuit.
(Connection output type)Continuous analog output is possible.
(1～5VDC output, 4～20mA output)

Easy maintenanceBecause there are no moving parts, maintenance is easy.
Our level gauges are compact and lightweight. And wetted parts have high corrosion
resistance. (SUS304 standard)

Easy installation
Available to resin tanks.

The example that increasing the diameter of the pipe

The use under adverse environmental conditions
HT type with SUS body is recommended in case ambient atmosphere is
exposed to corrosive gas and stronger material than SUS is required.

The stable measurement in places that there are
fast‑moving water, violent wave, foaming atmosphereis possible because the pipe prevents waves.

Depending on the use conditions
When using STB type

Initial adjustment liquid
If more stable and high precision measurement is required, please provide us the sample liquid to set
a level gauges according to the sample liquid. This can avoid troubles such as unnecessary readjustments
and the measurement impossibility.
If unable to do so, please let us know relative permittivity of the liquid to adjust according to theliquid of similar permittivity. The amount of the sample liquid is 2L per meter of measurement length.
If we select the adjustment liquid, we use tap water for water specification and cutting oil or kerosene
for oil specification.We will return the sample liquid basically. Please dispose of waste liquid.

Notes on specifications
Specifications in this catalogue are subject to change without notice to improve products.
Please contact us for other specifications.
Please note that our level gauges are not certified as intrinsically safe explosion‑proof
construction.

Order for products of special specifications
As for the integrated type and the separated type, head (tank attaching portion), pipe shape (pipediameter), material, and detecting portion (electrode length) can be changed. We will estimate for
special specifications separately.

Separated type

Instructions for use
Our level gauge series is basically drip‑proof construction and not waterproof construction.
Please install it not to soak the amplifier in the liquid. (For waterproof type, consult us.)
Please note that our level gauges are not certified as intrinsically safe explosion‑proof
construction. And whatsoever for any damages resulting from this level gauge.
We recommend the regular cleaning according to the measuring liquid though this level gauge isbasically maintenance free.

Power cable
Measure the distance from the installation location of a level gauge to a power supply (DC10〜30V) or a trunk terminal.
2.5m is standard. (It can be extended to arbitrary length.)＊Recommendation is within 10m because overlong cable causes a voltage drop when using linear output type(DC1〜5V).

If there are changes in conditions of the measuring liquid, the detection position may vary.
Therefore, we recommend that you allow a wide margin for adjusting the position and carry out a regular check.
