Operation manual of SMP858 series - 1

Flush diaphragm pressure/differential pressure transmitter quick installation manual Install pressure transmitter Safety precautions /l\ Pressure sensor/ transmitter shall be installed by professional engineers, technicians and other qualified personnel, please read carefully the content and important information provided by this installation guide and label before installation. /K Pressure sensor / transmitter is powered by an external power supply, the power supply should be in accordance with relevant standards stipulated by energy limitation circuit, and pay attention to the high-voltage that may exist in the circuit. /f\ The maximum static pressure overload has been marked on the label, the maximum pressure value should be no more than the span of sensor. ! Using pressure sensor/transmitter in dangerous situations, product installation, using and maintenance should comply with installation guide and relevant provisions of national standards. ! Measuring diaphragm is located in the forefront of the process connection, touch or squeeze with hard objects may cause damage to the diaphragm. ,--f\ Attention pleasel Disassemble the instruments under the condition of normal atmospheric pressure only. Direct installation Integrated pressure transmitter, installed directly with process connections. Brackets installation Label LEEC Pressure transmitter 2016/05/25 ^ i Important information n Static pressure overload a Power supply A Signal outline type n Explosion proof mark a Intrinsic safety equipment parameters n Certificate /t\ Please note! Exceeding static pressure overload will cause damage to the instruments, even lead to burst and casualties. Product UsagePipe pressure measurementContainer pressure measurement /K ■ The diaphragm seals system and pressure transmitter together form a closed calibrated system. Filling fluid through the diaphragm seals and the openings of pressure transmitters in the measuring system. The openings have been sealed. Please do not open.. ■ Please do not remove the protection cap of the isolated diaphragm. ■ To prevent capillary from overbending (bending radius: alOmm), please make sure stress relieving completely of the capillary before the installation. ■ The static pressure of the liquid column in the capillary may result in zero shift. It can be corrected by the display at site. In order to get more accurate measuring results and avoid instrument failure, Please note the following when mount capillary: ■ No vibration(avoid extra pressure fluctuation) ■ Do not mount around the heating pipes or cold pipes. ■ Should do heat preservation treatment to the capillary when ambient temperature is below or above the reference temperature. ■ Bending radius s 100mm. ■ If diaphragm seals system at both sides are adopted, the two capillaries should be same in length and ambient temperature. Gage vent Process connection Thread connection Differential pressure measurement system Flange connection /f\ When using DP diaphragm system measurement, the static pressure is near to vacuum, differential pressure transmitters should be installed lower 1 m than the high-pressure side pressure port. If there is any question, please contact Shanghai LEEG Instruments Co..Ltd. Tel: 86-21-31261976 Fax: 86-21-31261975 Email: info@leeg.cn, sales@leeg.cn
