简要说明：**牌的电压调整器是一种压力标准仪器产品：估价：89000，规格：**，产品系列编号：**

　　电压调整器是一种压力标准仪器，主要适用于校验低于0.25级精度的精密压力表，亦可用来校验低一等级的活塞式压力计，各种工业用压力表或其他各类压力测量仪器。电压调整器适合在周围温度为20±5℃，相对湿度不大于80%的条件下工作。
pressure controller is a kind of pressure, pressure controller is mainly applied to precision pressure gauge, check the accuracy of less than 0.25 on the Richter scale can be used to check the low level of piston manometer, all kinds of pressure gauges or other kinds of pressure measuring instruments used in industry. pressure controller for temperature of around 20 + / - 5 ℃, relative humidity under the condition of no greater than 80% of the work.
电压调整器乃是应用静压平衡原理的计量仪器：即活塞本身加在活塞上的专用砝码重量（G）电压调整器作用在活塞面积（S）上所产生的压力（P）与液压容器内所产生的压力相平衡，来测定被校验仪表的压力大小：
pressure controller is the application of static pressure balance principle of measuring instrument, the piston itself to add a special weight weight (G) on the piston effect of pressure controller in the piston area (S) on the pressure (P) generated by the container and the hydraulic pressure generated by the phase equilibrium, to determine the pressure of checking instrument size:
P=G/S
P = G/S
式中G＝mg(m:砝码质量，g：重力加速度)产品出厂时g值用标准重力加速度来定。电压调整器用户使用时g值应按妆当地重力加速度来定，并按计算值修正砝码G的重量。
Type of G = mg (m: quality of Jordan farmar, G: acceleration of gravity) products factory G value using the standard gravitational acceleration. When pressure controller for household using g value shall be determined according to makeup local acceleration of gravity, and counterweights of g correction according to the calculated value.
