These transmitter series uses a silicon resistance sensor formed from monocrystal silicon, a perfect material which has no hysteresis in pressure or temperature changes. The sensor minimizes overpressure, temperature change, and static pressure effects, and thus offers unmatched long-term stability. Its highest accuracy can reach 0.05% , highest pressure up to 40Mpa , its structure are stainless steel 316L and silicone oil welded seal . With Excellent performance and stability, It can replace some famous brand with a reasonable cost . It has 4-20ma output , support hart and RS 485 communication . OEM is available , BCST supply one step solution for transmitter .
