SMP858-TSF hygienic pressure sensor in line with international FDA, 3-A standard. It 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 40MPa, suitable for severe pressure overload situations. It fully adopts superb stainless steel and complete welding structure. The characteristics of rigorous seal and isolation, high temperature CIP and SIP cleaning, no hygienic dead angle when mounting and working, can truly meet the requirements of sterility and non-contamination.

1. High performance monosilicon pressure sensor with patented encapsulation technology
2. Vertical mounting three diaphragm protection structure can easily cope with high overload and high precision tests
3. Gauge vent locates on the end of the sensor, more suitable for low temperature, humid and condensation working condition.
4. Durable integrated tri-plane supports cylindrical stainless steel housing, tight and smooth, easy to clean.
5. Roughness of stainless steel surface Ra≤ 0. 4μm, conform to international sterile standard.
6. IP69k approved stainless steel design housing is achievable to clean the instruments.
