Measuring technology

The absolute Temposonics linear position sensors are based on the

proprietary magnetostrictive measuring principle. This combines various

magneto-mechanical effects and uses the physically exact velocity

measurement of an ultrasonic wave (torsion pulse in its sensor element) for

position detection. The sensor-integrated signal processing converts the

measured values directly into commercially available outputs. The non-contact

principle - an external moving magnet marks the position - eliminates the

problems of wear, noise and false signals and guarantees best durability

without recalibration.

Application examples:

The target in customer solutions is a high degree of efficiency and synergy to the product. During the design phase measurements need to be taken which

enable the product to meet customer requirements suitable for the application.

In this respect, close cooperative partnership between the customer and Temposonics is desirable.

All constructive measures relating to operating parameters (vibration, temperature and ESD) require consultation with Temposonics. This also includes

the CE marking of components used for installation.

Level measurement in medical technology

An analyser for immunodiagnostics applications uses magnetostrictive level sensors in containers to monitor the

levels of consumables and of the collected waste products of the analysis. Through continuos measurement, it is

always known how much fluid is in the containers. This enables continuous reloading without interruption of the

analysis and anticipatory planning.

Increased dosing accuracy, reduced consumption

The dosing accuracy during preparation of damping solution and precise control of the IPA concentration are of

considerable importance for the production and process stability in printing systems. The continuous discussion

relating to the toxic load of the ambient air at work places and the need for cost reduction in printing companies

also requires further reduction of isopropyl alcohol in the damping solution. The Temposonics® OEM-sensor plays

an important part for dosing of damping solutions and thus for decreasing the overall costs.

Position feedback in process measurement and control systems

The valve position feedback combines well-proven sensor technology and state-of-the-art design for optimized

applications. Our development activity focused on the requirements and wishes expressed by our customers in

the liquid processing industry.

In addition to safe control and monitoring of all functions of process valves in breweries, dairies, facilities for

production of fruit juice and production plants in the pharmaceutical industry, the C-Series provides a high degree

of efficiency.

Position feedback in steering systems

The customer-specific sensors are used to monitor the steering position of rear drives and to provide position

feedback. Based on the linear C-series position sensor, these sensors are equipped with a special housing, which

was developed by the end user and realized by Temposonics. The sensors measure the stroke of steering

cylinders on the port side and the bow side. Typically installed in multi-engine boats, the boat control system

uses the sensor signal to permit control of the boat movement using a joystick: A solution termed “Steer-ByWire”.

Cabin suspension

To reduce the human vibration, directive 2002/44/EC (human vibration directive) of the European Union has been

implemented into national law in March 2007. This directive defines binding limit values (reference period of

8 hours < value 0.5 m/s²) for the hand-and-arm area as well as whole-body vibration values, which must not be

exceeded.

These limit values are met by effectively reducing the induced vehicle vibration using C-series position sensors in

a cabin suspension system. The cabin suspension system permits reduction of the accelerations mainly in the Z

axis. Due to this reduction, the vibration load acting on the driver is alleviated considerably, without affecting

driving experience and operability.
