Industrial Sensors I EBV Special
specifications having the relevant length for usage in harsh industrial environments where EMC is an issue. The industrial pressure sensors are immune to electrical interferences of up to 30V/m. Across the whole temperature range of -20°C - +100°C the measurement error is less than 2%. At 25°C the measurement error across the entire temperature range is only 0.75% – this applies for more than 10 million specified pressure measuring cycles. Therefore the sensors are among, we believe, the most accurate on the market. The reverse polarity protected sensor’s operating voltage can be 6 - 30 VDC. Also the sensors can handle voltages up to 39VDC without damage. Vibrations up to 10g with a frequency of 25Hz – 2,000Hz do not harm the pressure sensors. The sensors can also sustain shocks of 100g coming from various directions with 6Hz (half sinus). In all cases the UL and RoHS compliant CE certified sensors make their measurement result reliably available after a response time of <10ms via the cost-efficient but IP6K9 protection rated Delphi-Packard connector on the output. As sealing material for the internal O-ring Sensata uses neoprene, hydrated nitrile rubber (HNBR) and fluorosilicone. The bursting pressure corresponds to the five-fold measurement pressure. Using a hexagonal screw terminal (1/8“ male, 1/4“ female) the pressure sensors are not only suited for industrial process automation applications but also for applications like pumps and compressors as well as HVAC (heating, ventilation, and
air conditioning) as well as in domestic appliances such as fridges and freezers. In the area of process automation, for example, there are important applications in the fields of hydraulic systems, pneumatics, lifts, liquids and gases. Some of the most important pump and compressor applications are industrial cleaning systems, (car) washing systems, water-based high-pressure cleaners, water and auxiliary pumps as well as pneumatic systems. The HVAC and fridges and freezers sector not only includes industrial freezing technology but also building automation, heat pumps as well as fridges and freezers for food and retail.
Win-win situation According to Ing. Roger Appelo, Business Development Manager for sensor products at Sensata in Europe. “We are now able to address an entirely new customer base, while EBV Elektronik will have access to a high quality and mature sensor technology that still holds plenty of potential. In our view this is a win-win situation for both companies. Mass producing the corresponding automotive sensors in quantities of several millions a year EBV will be able to offer pressure sensors at an affordable price.” Those EBVchips were developed partly in the Netherlands and partly in the US. The complete sensor including ceramic production will be fabricated in Mexico, where Sensata also produces it’s automotive sensors.
