The automotive industry is facing major challenges with the switch to electromobility (e-mobility), because an electric vehicle differs significantly from a vehicle with an internal combustion engine. Among other things, an electric vehicle requires additional sensors that function faultlessly in the harsh vehicle environment.

In some OEM projects, we have already achieved groundbreaking new developments in e-mobility together with our customers and project partners. The topic of HV (High Voltage) is playing an increasingly important role here, as high voltages can occur in the event of failures or short circuits. It must be ensured that any sensor and measurement technology can withstand this and continue to provide reliable values. Our sensors are prepared for the future, we subject all products to a so-called dielectric strength test, in which the functionality at high voltage (up to 10,000 V) is guaranteed.

High-precision temperature sensor for e-mobility

Together with a major automotive supplier, we are developing a cable sensor for use in the new generation of electric vehicles. The sensor is installed in a stator connection assembly and is equipped with a specially developed sensor. This high-quality temperature sensor ensures that temperature monitoring is guaranteed in the windings of the electric motor.

Special features of the temperature sensor:

  • High electric strength (HV) up to 5,000 volts
  • Very fast response time
  • Temperature resistant up to 200°C
  • Sensor is completely protected against external environmental influences

Temperature sensor for fuel cells

Together with a well-known global automotive supplier, we are developing a very robust temperature sensor that ensures temperature monitoring of the coolant fluid of a low-temperature fuel cell. The low-temperature fuel cell is used in forklifts, trucks and e-cars and converts chemical energy into electrical energy using hydrogen and oxygen. During operation, temperature monitoring is continuously ensured here in accordance with automotive standards. The sensor will be used internationally, but initially in Europe, Asia and the USA.

Special features of the temperature sensor:

  • High electric strength (HV) up to 5,000 volts
  • Very fast response time
  • High protection class IP67K (tightness against dust and the penetration of water at high pressure from a nozzle or steam jet cleaning from any direction)
  • High resistance to vibration and pressure
  • Resistant to various chemicals

Our temperature sensors are flexible, precise and individually applicable. Here we offer high quality and highly accurate temperature measurements, Made in Germany! Depending on the application, the requirements are different. We adapt to the customer’s application and realize customized and precisely fitting solutions. We can measure everything in the temperature range from -200°C to +1800°C.
