SMP858-NSF Monosilicon differential pressure transmitter SENSING TOMORROW Product information Brief introduction Monosilicon pressure transmitter SMP858-NSF monosilicon pressure transmitter is the best hygienic pressure transmitter meticulously designed by LEEG Instrument, with the world’s most advanced silicon pressure sensor technology and patent encapsulation process. SMP858-NSF adopts full isolation seal structure to eliminate the humidity effects, suitable for severe wet cleaning occasion; double diaphragm overload protection structure to achieve the highest overload pressure 24MPa, suitable for severe pressure overload situations; strong transient voltage resistance to meet the standards of level 4 (Differential mode voltage: 2000V, common mode voltage: 4000V), suitable for severe surge voltage occasion; seven temperature regions, 20 linearity points and 160 pressure calibration points, suitable for severe temperature change occasion. Those leading manufacturing technologies redifine the best quality of hygienic pressure transmitter. Main parameters Pressure types Differential pressure Measuring range 4kPa-1MPa, please refer to the ordering information chapter Output signal Pressure and level measurement Measuring medium Viscous, paste-like, adhesive, crystallising, particulatescontaining and contaminated media Disclaimer: all the data used in the product description is not legally binding.
