The pressure coefficient of resistance of manganin sensors was determined from isothermal pressure dependences measured at various temperatures in the range 77-352 K in fully hydrostatic conditions using a He-gas pressure system. The pressure coefficient decreases with decreasing temperature, reaches a minimum at about 110 K with a deviation of 5.0% from its room temperature value and then increases. Both below and above K the temperature dependence of can be approximately treated as linear with the rate equal to and , respectively.
