Exempt from timing pointer -type manometer

The utility model discloses an exempt from timing pointer -type manometer, include: including connecting rod (1), sector gear (2), spring pipe (3), hairspring (4), scale (5), pointer (6), its characterized in that: still include scale (5), each numerical value point scale of scale (5), with spring pipe (3) free end drives under the effect of measurement medium pressure sector gear (2) and connecting rod (1) leads to the corner that pointer (6) produced is consistent. The utility model provides an artifical timing in the past man -hour long, the precision is low, the poor stability scheduling problem, has characteristics such as the operating procedure is simple, the practicality is strong, precision height, has improved the production efficiency and the economic benefits of pointer manometer greatly. 本实用新型公开了种免调校指针式压力表，包括：包括连杆(1)、扇形齿轮(2)、弹簧管(3)、游丝(4)、度盘(5)、指针(6)，其特征在于：还包括度盘(5)；所述度盘(5)的每个数值点刻度，与所述弹簧管(3)自由端在被测介质压力的作用下带动所述扇形齿轮(2)和所述连杆(1)导致所述指针(6)产生的转角相致。本实用新型解决了以往人工调校工时长、精度低、稳定性差等问题，具有操作步骤简单、实用性强、精度高等特点，大大提高了指针式
