Bellows refers foldable sheet along a fold wrinkles stretch direction of the tubular elastic sensing element is connected into. Bellows widely used in instrumentation, the main use is as a measuring element of pressure measuring instruments, pressure is converted into displacement or force. Thin wall bellows, high sensitivity, the measurement range of tens to hundreds of MPa Pa. Its open end is secured, sealed end in a free state, and the use of auxiliary coil spring to increase flexibility. Work elongation under the action of the internal pressure of the tube along the longitudinal direction, the movable end produces a displacement pressure certain relationship. Events end driven pointer to indicate the size of direct pressure. Bellows displacement sensors are often combined with the power output to constitute a pressure sensor, it is sometimes used as a spacer element. Since the bellows extension requires a larger volume changes, so its response speed below Bourdon tube. Bellows adapted to measure low pressure. Company Website: www.xqgtw.com
