1 Characteristics
Simple and rugged construction
Applicable for liquids with density 0,5 kg/dm³
Measuring length 300 up to 6000 mm (11,8 up to 236“)
Applicable for small storage reservoir
Pressure rating up to PN40 (300 lbs)
Temperature range up to 130 °C (166 °F)
Material of transmitter housing: Aluminium or stainless steel
Protection class: IP65 NEMA 4X)
Different sensor-tube materials available
Sensor tube available in Plastic material
Current output: 4…20 mA (optional: HART)
2 Functional Principle
The level sensing transmitter type ITA-T1S will be installed vertically
on the top of a tank. Different types of tank-connections are available
(see order code). The electrical connection between level sensor and
transmitter is done on factory side (3-wire).
A float follows directly the changes of liquid level and moves along
the guide tube. Inside the float a permanent magnet system is
installed. This magnetic field operates directly to the reed switches
inside the sensor tube. While the reed-switches are activated the
result will be a change in the resistance load which corresponds
directly to the level.
The transmitter (f.e. type INT5333 or TMT182) allocates to the actual
level a current output between 4 and 20 mA.
If required on customer side the movement of the float can be
reduced by using adjustable float stops.
3 Indicator
Measured values can be displayed directly on site by the optionally
available LCD digital 4 ½ digit indicator. The indicator is freely configurable
by means of a DIP-switch. Values in between 0 and 19999 can be
indicated. When supplied, the device has been configured to the clients’
requests. If no requests have been received, the configuration is 0-100 %.
For indication of the measured value the DigiFlow 520 can be connected
directly to the sensor type ITA-T1S. The DigiFlow 520 shows the actual
value in most of all engineering units (see fig. 3). Linearization of various
tank shapes can be done in the indicator.

4 Interface Measurement
The level measurement of liquids with different densities in one tank –
interface measurement- is a big problem for a lot of competitors. In this case
it is important to measure the level of two liquids in one tank (see fig. 4). This
function will be solved while using the ITA-T1S. Depending on the difference
of density the float will be designed to measure the interface.
