We aspire to top quality for every one of our products, and that is guaranteed through recognized, measurable quality standards. We have created the basis for this by introducing an ISO 9001 quality management system and gaining certification under the IATF 16949 automotive standard.
The CCT pressure temperature sensor is installed in climate control systems, particularly in vehicles with alternative drives, and heat pumps. The specially developed thermoreceptors permit a fast response time in flowing media and guarantee high temperature accuracy. The design excels due to its compact size and minimal weight, which makes it easy to integrate and ideal for lightweight systems. The specific evaluation electronics make the pressure and temperature signal available via a digital single wire interface (LIN). High quantities can be realised at an affordable price thanks to fully automated production.
The Climate Control Pressure Transmitter (CCT) was specially designed for measuring the pressure of vehicle coolants. The hermetically sealed, robust aluminium case makes this sensor an affordable solution for vehicle climate control systems. Its high-quality stainless steel measurement element makes the CCT not only compatible with a broad range of media, but also ideal for high-pressure applications (R744). Its innovative evaluation electronics provides reliable, precise measurement data over a broad temperature range. Specially adapted to meet the needs of the automobile industry, the CCT also fulfills current EMC and ESD regulations.
One of our smallest pressure sensors, the VSP has a robust and submersible design which makes it a reliable partner for any oil pressure application in motor and commercial vehicles. The VSP is able to measure absolute or relative pressure in a nominal pressure range of up to 600 bar. The specially developed evaluation electronics make it possible to take very precise and stable measurements at temperatures of up to 150 °C, even under tough conditions. In addition, the VSP also complies with the high ESD and EMC standards applicable in the automobile industry. Our assembly machines have a wide range of flexible settings enabling a customised production of the sensor and an optimal adaption to the respective application.
The pressure transmitter module (PTM) responds to the general trend towards miniaturisation and cost efficiency. Its ideal construction size ensures that the sensors of the PTM series are easy to use and versatile in applications where installation space is scarce. The modular design with a wide range of possibilities for electrical and mechanical interfaces also permits easy integration in existing customer systems. The use of highly accurate evaluation electronics directly on the ceramic pressure cell permits the output of a temperature-compensated analogue signal or digital signal. Stable, exact measurements are generated over a broad temperature range in the process, also under adverse conditions.
The IPS pressure sensor is used in applications requiring a sensor with a high degree of robustness and media compatibility. The IPS is a reliable partner and provides precise and stable measurements over its entire life, even when used in tough conditions, when handled roughly and when exposed to high levels of vibration. The pressure sensor elements and pressure connectors are made of stainless steel and designed for absolute and relative pressures of up to 600 bar. The IPS is excellently suited for use in oil, petrol, diesel, H2, CNG and LPG applications. The sensor‘s flexible design with a wide range of electrical connectors and output signals also means it can be adapted to fit any system perfectly.
When it comes to vibration resistance and excellent compatibility with engine and gear oils, motorsport customers are not the only ones impressed by the XKP pressure sensor. The XKP comes in a variety of design set-ups with two different wrench sizes and multiple electrical connections, making it the ideal pressure sensor for automotive and motorsport applications. Its reliable and precise measurements make the XKP outstanding for use in mobile test stations. And of course the pressure sensor meets the usual EMC and ESD requirements in the automobile industry.
The mathematical differential pressure sensor (MDPT) was specially developed for measuring differential pressure in diesel particulate filters (DPF). The MDPT consists of two robust independent pressure sensors, which measure pressure upstream and downstream of the filter. The pressure difference is determined by means of a patented mathematical method with the help of a micro-controller. This setup makes it possible to output the system pressure in addition. With its innovative concept, the MDPT also supplies accurate and stable measurement data over the entire lifecycle, even under adverse operating conditions. The design with properly configured pressure connections guarantees installation that is resistant to freezing. Developed for the utility vehicle industry, the MDPT of course also meets all industry requirements with respect to EMC and ESD.
The LMS mass air flow sensor was specially developed for measuring air volume in connection with emission and motor control in vehicles. Based on the measurement principle of a hot film anemometer, the mass air flow sensor consists of temperature sensors and heaters each arranged in pairs. This arrangement permits bidirectional measurement, which makes backflow and pulsations detectable. The modern semiconductor hot film technology ensures fast response times as well as reliable, stable measurements over the entire life cycle. Application specific, electronic calibration of the mass air flow sensor also guarantees high precision and a characteristic curve that is fully attuned to the respective system. Its compact design featuring a flange mount not only permits simple integration in the flow channel (pipe), but also guarantees flexible installation in a wide range of systems. The LMS can also be optionally equipped with a temperature sensor for additional measurement of the media temperature.
The VST temperature sensor is used in applications that require a high degree of flexibility and special adjustments. The compact design and use of media-specific materials makes the VST ideal for use in applications with critical installation space requirements and under harsh ambient conditions. The specially developed measurement element not only guarantees fast response times, but also highly accurate results. The sensors are available in a resistive configuration with an NTC element or PT100/ PT1000 element. As a transmitter version with a linearised, analogue output signal, the VST also offers electrical protective and diagnostic functions, which are typical for the automotive industry.
