Abstract
A combined pressure and temperature sensor comprising a tubular member 3 of circular cross section having a closed end and an open end, the open end, in use, connecting to a pressurised environment such that the interior of the tubular member is exposed to the pressure, a flat or preferably a symmetrical distribution of flats 1 being formed on the outer cylindrical surface of the tubular member 3, and a sensor element 2 mounted on at least one said flat 1, which sensor element 2 is sensitive to the strains in the tubular wall of the tubular member 3 resulting the pressure in the interior thereof and the temperature of said tubular member.
Claims18
A pressure sensor comprising a tubular member having a closed end and an open end, the open end, in use, connecting to a pressurised environment such that the interior of the tubular member is exposed to the pressure, at least one flat formed on the otherwise circular outer cylindrical surface of the tubular member, and a sensor element mounted on said at least one said flat, which sensor element is sensitive to the strains in the tubular wall of the tubular member so as to be responsive to changes in pressure in the interior of the tubular member.
A combined temperature and pressure sensor comprising:
- a tubular member having a closed end and an open end, the open end, in use, connecting to a pressurised environment such that the interior of the tubular member is exposed to the pressure;
- at least one flat formed on the otherwise circular outer cylindrical surface of the tubular member;
- and
- a sensor element mounted on said at least one said flat, which sensor element is sensitive to the strains in the tubular wall of the tubular member so as to be responsive to changes in both the pressure and the temperature in the interior of the tubular member.
A combined temperature and pressure sensor comprising:
- a tubular member having a closed end and an open end, the open end, in use, connecting to a pressurised environment such that the interior of the tubular member is exposed to the pressure;
- at least two opposing flats symmetrically formed on the otherwise circular outer cylindrical surface of the tubular member;
- and
- a sensor element mounted on at least one of said flats, which sensor element is sensitive to the strains in the tubular wall of the tubular member resulting from changes in temperature and pressure within the tubular member so as to enable measurement of both the pressure and the temperature in the interior of the tubular member.
