Temperature characteristic of diaphragm pressure gauge

&Nbsp;      diaphragm pressure gauge system by filling the sealing fluid transfer medium pressure, because the sealing temperature contraction coefficient of liquid, the pressure gauge with pressure decreasing temperature indication is also reduced, its temperature and sealing liquid contraction coefficients, temperature diaphragm stiffness and compression, especially on the low range pressure gauge, is more significant. Rules of individual pressure temperature error is not greater than 0. 1%÷℃。 Diaphragm pressure gauges the overall temperature affect are affected by General instrument temperature and diaphragm mounted pressure temperature between and.
