Sensor arrangement

摘要

A sensing device for measuring temperature and pressure of a fluid medium in a pump housing. The device includes a common housing for containing a temperature sensor and a differential pressure sensor. The housing includes a temperature-sensor housing portion and a pressure-sensor housing portion disposed along a common axis. The temperature-sensor housing portion has a substantially cylindrically shaped projection configured for insertion into a corresponding bore in the pump housing and which sealingly encapsulates the temperature sensor therewithin. The projection has pressure measurement apertures defined in its side wall near the free end of the projection for communicating fluid pressures in the pump housing to the differential pressure sensor which is sealingly enclosed within the pressure-sensor housing portion.
