Features
SS301 series liquid pressure sensor takes advantage of piezoresistive technology. The sensor is fully media-isolating with stainless steel and no internal elastomer seals. This design often makes them resistant to harsh, aggressive media and challenging environments. The high-performance pressure sensor is laser welded with the housing. No O-ring, no potential leak problems. Extensive transducer characterization ensures high measurement accuracy.
SS301 series offers a pressure range of a minimum of 0.2 bar and a maximum of 200 bar (20 kpa to 20 mpa) for OEM applications. A lot of options and variants are available. It fully adapts to customer requirements and is ideal for industrial measurement and environmental control.
