下一篇：SPB3051 Differental Pressure Transmitter
上一篇：SST/SPB Single flange differential pressure transmitter


SPB and SST series capacitive transducer has the advantages of novel design principles, variety complete specifications, installation is simple, intrinsically safe explosion-proof, etc.Especially in the high precision, small volume, light weight, strong resistance to vibration, easy to adjust, long-term stability is high, the one-way overload protection characteristics well.
SPB and SST series capacitive transducer, including pressure, differential pressure, absolute pressure, flow, playmate varieties, such as its option, signal system, installation completely consistent with the rest of the world products, and we also implement the "IEC standards, and price advantage obviously, is the best choice for your ideal.
