The 433S is a vacuum transmitter developed based on BCM absolute pressure sensors with low measuring ranges and greater accuracy. Based on piezoresistive technology, the vacuum transmitters are provide absolute measurement for pressures from 0~400mbar to ~800mbar. With wetted parts, the 433S is made with 316L stainless steel, and employs a completely welded structure. This removes the o-ring seal in the inner cavity, which improves reliability and overall performance.
There are multiple options available for the mechanical interface that make the model perfect for applications in medical equipment, scientific research and other vacuum systems. Along with the customization process connection, electrical interfaces are available based on requests of the customers.
