Areas of Application and Advantages

BEDIA intelligent tank sensor ITS 65 is used to monitor the filling levels of oils of any kind. The sensor is able to automatically recognize and what kind of oil (hydaulic oil, engine oil etc.) is present and calibrates itself to it.

The capacitative measurement principle permits measurement of levels without mechanically moving parts. This considerably increases stability and operating safety.

The ITS 65 also offers detection of the medium’s temperature via a Pt 10000, which is attached to the tip of the sensor. Due to their rugged design, high IP protection classes and a working temperature range from -50 °C to +150 °C (-58 °F to +302 °F) the BEDIA intelligent tank sensor ITS 65 is primarily used in the following areas:

• Construction machinery
• Agricultural machinery
• Commercial vehicles and busses
• Engines
• Hydaulic power-train control systems

These high-power bimetal operated temperature switches are available either with normally closed (NC) or normally open (NO) contact configuration.

The robust round metal enclosure accommodates a resilient preloading disk, a bimetal disk and a silver contact. The compact switch system is covered by means of a plate which also carries a silver contact and is isolated from the enclosure by means of an isolating washer. The resilient preloading disk ensures excellent performance.

The electronic temperature switch of BEDIA is fitted with thin-film resistor Pt 1000 in a bridge circuit. This sensor element provides close switch point tolerances and a quick response. Switch point and reset hysteresis may be selected within the admissible operating range when ordering so as to allow the monitoring of both very wide and very close temperature ranges. The switching output is protected from short-circuit and overload.

This temperature sensor is for measuring the temperature of liquid and gaseous media in engines, sets of machines and utility vehicles.

A Pt 1000 thin-film precision resistor is used as the measuring element. The temperature-dependent resistance of the Pt 1000 is evaluated by an electronic circuit and outputted as a temperature-dependent voltage at the sensor‘s output. The interrelationship between temperature and voltage corresponds to the characteristic curve for the Pt 1000 and is thus nearly linear.

Temperature is one of the most measured physical parameters. Despite this, precise temperature measurement is one of the most difficult tasks in motor technology. To meet the constantly increasing requirements for improved motor performance, higher efficiency and reduced emissions, it is necessary to use reliable and precise sensors in modern motor control systems. Temperature has a decisive influence on process efficiency, energy consumption and other parameters. Even the service life of machines, equipment and motors is affected by temperature conditions. In many industry sectors, the most important factor is to use the information from reliable temperature measurements for control and regulation functions.
