Further, pressure transducer gland is provided with and installs the grooving of pressure transducer and location structure and line outlet groove.
This utility model has the advantage that
1, directly detection acts on the pressure on syringe piston rod tail end, is greatly improved real-time and the accuracy of pressure detecting.
2, simplify assembly technology, compact conformation, and do not destroy the terseness of syringe pump overall appearance.
3, increase water-proof function, up to higher classification of waterproof requirement, reduce pump housing feed liquor during injection and make the risk of internal electric elements short trouble.
Below in conjunction with the accompanying drawings this utility model is further described.
