YS series piston pressure vacuum gauge -0.1~0.25, 0.6MPa

overview

YSPiston type pressure vacuum gaugeMainly used in metrology rooms, laboratories, etc. as a reference instrument for calibrating precision pressure gauges and sensors. Piston pressure gauges are also directly applied to the high reliability monitoring process for the calibration of other local instruments. YS-2.5 model parameters correspond to THLL210.

The piston and piston cylinder are finely ground, resulting in minimal roundness error and clearance. The working medium used is low viscosity sebacic acid grease, which greatly improves the duration of piston rotation and correspondingly reduces the descent speed of the piston, thereby improving piston discrimination ability. The working position of the piston is visually monitored, which has the advantages of being eye-catching and accurate. The weight has been corrected for pressure deformation coefficient and local gravity acceleration,0.02Demagnetization treatment shall be carried out for levels above. When sending for inspection, only the piston measurement system needs to be sent for inspection, which is small in size and light in weight.
