压力继电器的主要性能有以下几个方面。

(1)调压范围

压力继电器能够发出电信号的低工作压力和高工作压力的范围称为调压范围。

(2)灵敏度与通断调节区间

系统压力升高到压力继电器的调定值时，压力继电器动作接通电信号的压力称为开启压力;系统压力降低，压力继电器复位切断电信号的压力称为闭合压力。开启压力与闭合压力的差值称为压力继电器的灵敏度。差值小则灵敏度高。为避免系统压力波动时压力继电器时通时断，要求开启压力与闭合压力有一定的差值，此差值若可调，则称为通断调节区间。

(3)升压或降压动作时间

压力继电器入口侧压力由卸荷压力升至调定压力时，微动开关触点接通发出电信号的时间称为升压动作时间，反之，压力下降，触点断开发出断电信号的时间称为降压动作时间。

(4)重复精度

在一定的调定压力下，多次升压(或降压)过程中，开启压力或闭合压力本身的差值称为重复精度，差值小则重复精度高。
