Product Description

The model 315M is a capacitive differential pressure transducer with all welded stainless steel construction. BCM 115C differential pressure sensor is integrated inside the 315M. Thanks to the unique structure of metal capacitive working principle, the 315M transducer can measure low differential pressure down to 0~16mbar and sustain high static pressure up to 320bar.

Different types of fill fluid are available for this model for different applications. The fill fluid can be the standard type-a fluid for common industry of general purpose, the type-b fluid suitable for oxygen industry, or the type-c fluid suitable for tobacco industry.

With the large diameter diaphragms, the 315M can measure pressure of either viscous paste or fluids containing solid particles. Moreover, Tantalum, Hastelloy-C, or Monel diaphragms are available on request for more corrosive media applications in case 316L stainless steel is no longer applicable.

For temperature measurement, a temperature sensor (e.g., a thermal diode or a thermal resister) can be integrated into the 315M on request.
