Explanation of the formula for reading value conversion of vacuum box vacuum meter

How is the reading value of the electric-heated vacuum box vacuum meter calculated and how can we see the meaning of the vacuum value? The following is our company's conversion of the vacuum degree of the electric-heated vacuum box; according to the scale value range of this table, the value of the vacuum degree and the relative value can be converted by the following formula:

P=1×105 (1-δ/0.1)P-Vacuum degree value (Pa)

δ-Scale Display Value of Vacuum Table

Example 1: The representation value of the table is 0.1, then P=1×105 (1-0.1/0.1)=0Pa is vacuum.

(Vacuum does not exist)

Example 2: The representation value of the table is O, then P=1×105 (1-O/0.1)=1×105Pa=1 atmospheric pressure

Example 3: The representation value of the table is 0.08, then P=1×105 (1-0.08/0.1)=2×104Pa

The vacuum degree of the electric heating vacuum box mainly depends on the performance of the supporting vacuum pump.

The vacuum degree measurement unit of the electric heating vacuum box is converted as follows:

0.1Mpa=1×105Pa=760mmHg=1 atmospheric pressure

1圹=1mmHg=133.33Pa

2圹=0.00026666Mpa≈267Pa

(2) The vacuum meter readings of the electric heating vacuum box can be displayed with intuitive numbers. But the price is relatively expensive and is generally applicable to scientific research institutions. Our company also has vacuum degree digital display control type.
