Performance characteristics
The PD-750QC sanitary differential pressure transmitter adopts single crystal silicon pressure sensor technology and patented packaging process, carefully crafted into the strongest sanitary pressure transmitter. Adhering to the design concept of fully meeting harsh usage scenarios, the PD750Q monocrystalline silicon sanitary pressure transmitter adopts a fully isolated and sealed structure to eliminate the influence of humidity, making it suitable for harsh wet cleaning environments; The double diaphragm overload protection structure can withstand a maximum pressure of 42MPa and is suitable for harsh pressure overload situations; The transient voltage resistance meets the fourth level standard (differential mode voltage: 2000V, common mode voltage: 4000V), suitable for harsh surge voltage situations; Seven temperature zones with 20 linear points and 160 pressure calibration points, suitable for harsh temperature changes.
■Monocrystalline silicon pressure sensor with dual diaphragm overload protection structure, capable of handling high overload tests with ease.
■The signal transmission module of dedicated integrated circuit and surface packaging technology has user-friendly button parameter operation function and fast display of measurement data.
■Complete global or industry standard process connections such as ISO228 and DIN3256, exquisite stainless steel welding technology and surface treatment processes, and compliance with hygiene standards.
■The sturdy one-piece stainless steel shell ensures a long service life.
■The surface roughness Ra of stainless steel is ≤ 0.4 μ m, which meets the sterile standard.
■Warranty: Valid for up to 3 years
