Tantalum (Ta) and fluoroplastics (F4).
Flange material: stainless steel 0Crl7Nil2M02(316);Stainless steel lined with fluorine
plastic (316+F4).
Sealing gasket material: nitrile rubber;Fluorine rubber;Silicone rubber and fluorine
plastics.
Ordering instructions
1. Please specify the model, name, measuring range, measuring media, working
temperature, connection form and size, and accuracy grade.
2. If you have any special request, please specify in the order.
3. The diaphragm pressure gauge shall not disassemble or replace the configured
instrument so as to avoid the impact performance of the filling liquid.
4. before order, according to the characteristics of the measured medium, such
as corrosion resistance, easy to solidification, easy to crystallization, corrosive,
according to the characteristics of measured medium choose stainless steel
pressure gauge or with different corrosion resistance material isolation diaphragm
of diaphragm pressure gauges, high temperature environment to use high temperature melt diaphragm pressure gauge, the general medium such as (water, on copper or copper alloy no corrosive gas) such as usable general pressure gauge.
The working steps are as follows:
1. The replacement pressure gauge must be qualified by the metrological department with lead seal, and the pressure gauge in the validity period of the calibration or the new form with the factory certificate.
2. Before changing the table, the three-way cock must be rotated to the position of
the flushing pressure gauge to flush the dirt in the pipe.
3. Rotate the three-way cock to the position of holding water in the pipe, and use the wrench to remove the old watch and replace it with a new pressure gauge.
4. Rotate the three-way cock to the normal working position, and put the new watch into operation.
