How should a monocrystalline silicon pressure transmitter be maintained at ordinary times?

Time:2018-05-03

The maintenance of LEEG monocrystalline silicon pressure transmitter is divided into daily maintenance and periodic maintenance, daily inspection or through DCS, PLC and other system readings to observe whether the display value of the monocrystalline silicon pressure transmitter is in the normal range, and see if there is leakage in the pressure pipe and joint; each interval needs to inspect the zero of the monocrystalline silicon pressure transmitter. Whether the parts are intact, whether the lightning grounding wire is firm, the nameplate or the mark is damaged, etc., test whether the power supply power supply of the monocrystalline silicon pressure transmitter is normal, whether the signal output circuit is intact, no break or short circuit, and check whether the pressure value displayed by LCD and DCS, PLC and other upper computers are checked in the month period. The control system shows that the value is consistent without error; the discharge, discharge and emptying operation of the three valve group and the pressure tube are carried out at the time of the quarter or summer winter climate change, to avoid the error or accident caused by the blockage; in accordance with the relevant state regulations, the monocrystalline silicon pressure transmitter will be reexamined at least every year, if it is the measurement precision. The calibration period can be shortened to three months.

LEEG monocrystalline silicon pressure transmitter is used in petrochemical, chemical, energy, electric, steel, cement, papermaking and other large process industries. The fully isolated package monocrystalline silicon technology pressure sensor has excellent transient voltage impact resistance in principle and high precision measurement and long-term stability in the harsh process industry. Qualitative.
