Hua Chen instruments, diaphragm pressure gauge accessories, diaphragm pressure gauges provided by Hua Chen instruments. We are Qingdao Hua Chen Instrument Co., Ltd. (www.qdhuachen.cn) at: Qingdao specializes in: pressure gauge, stainless steel pressure gauges, pressure gauge accessories, special gauges 1, the instrument must be vertically: the installation should use the 17mm wrench tight, strong pressure gauge should not twist the case; transport should avoid the collision; 2, the instrument should use in an ambient temperature of -25 ~ 55 ℃; 3, using the work of environmental vibration frequency <25HZ, the amplitude of no more than 1mm; 4, use due to the ambient temperature is too high, indicating the value of the instrument does not return to zero or appear showing the value of tolerance seismic diaphragm pressure gauge, you can cut the upper case sealing rubber plug, the instrument cavity and the atmosphere can be; 5, instrumentation range should be between the upper 1/3 to 2/3; 6, in the measurement of corrosive media, may crystallize medium viscosity of the medium should be added to the isolation device; 7, the instrument should always be check (at least every three months), if found fault should be repaired; 8, the date of the instrument from the factory, within six months if found to fail due to poor manufacturing quality or damaged diaphragm pressure gauge manufacturers custody under normal conditions of use, by the company responsible for repair or exchange; 9, corrosive media measurement instrumentation required in order should specify the required condition. 1, the installation location should be consistent with the gauge mounted state requirements chemical diaphragm pressure gauges, dials generally should not be placed horizontally level installation location should facilitate staff observation. 2, at a distance gauge installation and measurement points should be as short as possible, to ensure the integrity of the seal, can not appear leakage. 3, the pressure gauge should be attached to the tip of the buffer; for ease of inspection, at the bottom of the instrument shall be equipped with shut-off valve; when the media is dirty or pulse pressure, we can use filters, buffers and regulators gas.
