Dead weight pressure gauges or press MTU 60

Dead weight pressure gauges or press MTU 60 are designed to calibration of indicating pressure gauges and pressure gauges model. Calibration of reference pressure gauges class. so 0,15 produced on presses with accuracy class of 0.02.

Verification is carried out in two ways:

1. By setting the column reference of various goods denominations, included into the delivery set. These create the necessary cargo the pressure across the piston of the column affects the working environment (oil, the air coming in calibrated pressure gauges. This method allows you to check two shows manometer.

2. Method comparisons. When the desired pressure is created manually, and showing the gauge is tested on a model, by comparing their the readings.

Verified element of dead weight pressure gauge is column with weights. The certificate of state verification specified the value of the acceleration of free fall. When the discrepancy between the values of the local acceleration of free fall privetnomu in the calibration certificate must to introduce a correction according to the formula:

where P is the pressure rating indicated on the goods:

gm is the acceleration of gravity at the place of operation, m/S2

gn-normal acceleration, 9,80665 m/S2

In order for the calibration of dead weight pressure gauge preferably to specify the value of the acceleration of free fall. This value may be specified under the all-Russian acceleration or under local value, at the place the operation of the device. In the first case, you can check the devices with accuracy class not higher than 1.0.

Specifications:

Measuring range: 0,1-6,0 MPa (1-60 kg/cm2)

Accuracy class: 0,05; 0,02
