First Sensor is one of the world's leading suppliers in the field of sensor systems. Our company develops and manufactures both standardized and tailor-made sensor solutions for applications in the Industrial, Medical and Mobility growth markets. With over 800 employees, we are represented at six German locations and also have development, production and sales sites in the USA, Canada, Singapore, China, the Netherlands, Great Britain, France, Sweden and Denmark along with a worldwide partner network. First Sensor develops and manufactures high-quality, customer-specific sensor solutions for the detection of light, radiation, pressure, flow, level and acceleration. The company produces in-house and along the value-added chain from component to system level. First Sensor AG is listed in the Prime Standard of the German stock exchange in Frankfurt. We guarantee our compliance through regular successful certifications of the sites according to ISO/TS 16949, ISO 14001, EN ISO 13485, EN 9100 and ISO 9001 - matching the respective business field.


We offer our customers tailored solutions that are developed and produced in accordance with their requirements. This can range from modifying a platform-based product to developing a completely new special sensors or designing an integrated system with multiple components, such as valves, pumps and microcontrollers.

Liquid Level Sensors

Fluid level control sounds quite easy but can turn into a demanding sensor application problem if movement, foaming, or media and container issues come into play. To reliably monitor the liquid level in tanks or containers, First Sensor offers a range of different sensor technologies. Depending on the application, they can register the level continuously or using limit values.

High Pressure Sensors

First Sensor develops and manufactures a large selection of highly accurate and reliable pressure sensors and pressure transmitters for air, gas and liquids. The sensors either provide basic mV signals or fully signal conditioned analog or digital outputs. Our rugged industrial pressure transmitters use ceramic or stainless steel pressure sensor elements to achieve high media compatibility for corrosive liquids and gases.

Thermal Mass Flow Sensors

Our thermal mass flow sensors record even smallest flows fast and with high precision. Within a modular technology platform First Sensor provides complete packaging technologies so as to realize complex custom specific solutions from individual chip elements. Further, our differential pressure sensors detect ultra-low pressure drops in volumetric flow measurement applications.

Ionizing Radiation Sensors

Alpha, beta, gamma, and X-ray radiation can be detected with silicon PIN photodiodes either directly via the absorption in the crystal lattice or indirectly via the measurement of the luminescence radiation of a scintillation crystal. First Sensor develops and manufactures customized photodiodes, detector arrays, and complete systems adapted to your specific requirements.

High Precision Optical Sensors

First Sensor develops and manufactures a large selection of photodetectors with high-sensitivity, high-speed, and low-dark-current which can be adapted to your specific requirements. Our sensors are optimized for ultraviolet, visible, and infrared light as well as ionizing radiation. Package solutions include surface mount (SMD) and through-hole (THD) devices. Further, we provide silicon photomultipliers for the detection of lowest light levels.
