Specifications quote DN25 without display / range-demand 630 yuan / Taiwan DN25 with display / range-demand 750 yuan / sets default flanges DN25, the need for other flange dimensions, please after confirming price and delivery and on-demand customer choice and leave a message in the remarks column. Other parameters consistent with the conventional type, just over the flange. Products WMB2088-FL Product Information Name: 2088 Pressure Transmitter Brand: Ye Li Industrial Product Number: WMB2088-FL Color: Army Green Features pressure transmitter pressure sensitive core using high-performance silicon piezoresistive pressure oil-filled core body, internal ASIC converts sensor millivolt signal into a standard long-distance transmission current signals can be directly with the computer interface card, control instrumentation, smart instrumentation or PLC connected convenience. The products are widely used in industrial process control, petroleum, chemical, metallurgy and other industries. Structure Representation WMB2088-FL-01 from the shell of the pressure transmitter, amplifiers, terminals composition, according to the needs of users can use the pointer table, LCD meter display. Product wiring diagram WMB2088-FL-02 open the instrument cover (terminal side), see terminals, power connectors as shown on the left. The main technical parameters ⑴ Working temperature: -20 ℃ ~ 80 ℃ (temperature to be customized); ⑵ transmitter accuracy classes are divided into: 0.25, the basic error of ± 0.25; 0.3 step, the basic error of ± 0.3; 0.5 级The basic error of ± 0.5 (range of basic error in percentage). ⑶ thermal zero shift ambient temperature deviates from the reference operating conditions, the transmitter zero drift should be less than 0.03% FS / ℃. ⑷ thermal sensitivity drift ambient temperature deviates from the reference operating conditions, the transmitter's full-scale drift should be less than 0.03% FS / ℃. ⑸ insulation resistance at reference operating conditions, the transmitter of each terminal to ground insulation resistance shall not be less than 20MΩ / 250V. Installation ⑴ choose easy to operate and maintain places for installation; ⑵ should be kept away from the vibration source mounting; ⑶ should be kept away from heat sources installation; ⑷ installed directly in the pipeline or equipment, the installation of the clamp with a wrench in the six-party transmitter place. PS: zero gain adjustment of zero and gain adjustment method: pressure gauge at the factory, has been calibrated, no user adjustment again. If it occurs in the course of the zero and span deviation, provides for an annual school inspection can be re-calibrated on a high level of precision pressure source. As follows: in the absence of pressure, adjust the zero potentiometer Z, so that current output is 4.000mA. Plus full scale pressure, adjust the gain S potentiometer, the current output is 20.000mA. So repeatedly, and finally to gauge zero and span adjustments to the standard value. Safety Precautions ⑴ removal and installation of the transmitter should be careful to avoid collision and affect the performance of the circuit. ⑵ within transmitter isolation diaphragm into the pressure port, do not touch the man with a foreign object. ⑶ transmitter must pay attention to the external threads of the seal, which will cause the pressure may not instability. ⑷ barrier required to obtain proof certificate, its installation requirements of the specification should be. ⑸ in the use of the product if you have questions, please contact me, an exception occurs in the product, please do not open repair, should not hesitate to contact us.
