How ITS-65 is different from ITS-60?

ITS65 is designed for hydraulic and engine oil level monitoring applications where the temperature of the medium could be up to 150°C.
Increased operating temperature range (-40°C to 125°C).
The ITS-65 has one level output and one optional output.
Sensors configured with CANbus J1939 can indicate both the level and temperature parameters simultaneously and with
customer software via a CANbus controller can indicate multiple level switch points, and temperature setpoints.
ITS-65 with a temperature output includes a temperature element at the beginning of the circuit board.

Compatible CANbus Controllers

The ITS series level sensors which are configured with a CANbus J1939 output can be easily interfaced with most CANbus based I/O controllers
DFX Technologies offers a variety of CANbus controllers compatible with the ITS series sensors. These modules are designed for heavy-duty mobile applications utilizing solid-state technologies.
The SS8 is DFX’s most powerful CANbus controller with 8x outputs, 3x analog/digital inputs, 2x serial communication ports for Modbus RTU RS-485 and CANbus J1939. This product is also embedded with IOT technology when remote monitoring and control are required.
The SS8 can be provided with custom software specific to customer requirements.

ITS-Series Sensors
What is capacitive measurement principles?

ITS series sensors use capacitive level measurement technology to accurately maintain correct level indication regardless of the variation in permittivity of different media types. A capacitor is formed by an electrically conducting plate and an aluminum tube. Depending on the level, the remaining air volume between the measurement electrodes varies. The resulting capacitive change
is detected and processed by the microcontroller.

The ITS sensors are equipped with a proprietary sensor structure that automatically calibrates the medium type. This calibration occurs at levels as low as 50%. Having a sensor that is capable of auto-calibrating, based on medium type or medium quality is an important feature for industrial equipment.

Conventional capacitive sensors available on off-highway industrial market are usually designed to measure only one specific medium type. This inability to correctly measure different medium types could lead to inaccurate measurements of up to 50% due to aging or change of the fuel and oil types.

ITS Sensors – Tank geometry

Irregular shaped tank geometry is becoming more common when OEMs are trying to utilize maximum space in their equipment designs.
Having a non-linear tank design helps by increasing tank volume, however, it also makes measuring accurate tank levels an almost impossible task. Luckily, the ITS-60 and ITS-65 can be calibrated to adjust for the irregular tank designs.
Calibration is accomplished by measuring 15 equally spaced reference points inside the tank from the bottom to the top of the tank. Volume is then calculated for each reference point. This data is then programmed into the sensor’s microprocessor during the manufacturing process. Each sensor then goes through extensive automated testing procedure to verify that parameters meet the customers specifications.

ITS Series Sensors Output Signal Types

CAN: CANbus J1939
Voltage (0-5V)
Current (4 -20 mA)
Resistance: 240-33 Ohm, 10- 180 Ohm, 0-90 Ohm, and custom Ohm ranges

ITS Sensors –Switched Outputs

For some applications having an accurate level indication is not enough. Each ITS sensor can also be configured with a switched output. Applications include low level alarm, high level shutoff or even the ability to shut down and engine prior to the engine running out of fuel.
The ITS series sensors can be configured with either a low-side or high-side output signal.
Switched outputs are short circuit protected and suitable for 500 mA.

ITS Sensors – Available Connectors

The ITS series sensors are available with a variety of connector options. Standard connectors for the US market include M12x1, solenoid valve connector or a Deutsch DT04-4P.
The ITS-60 and ITS-65 can be also supplied with only flying lead cable to any length. This cable option gives our customers and our wire harness fabrication department the ability to add any customer required connector.
