Rosemount 2088 Pressure Transmitter

Productoverview:
Rosemont 2088 pressure transmitterTo ensure high reliability and high precision, at the same time the price is attractive.Rosemount2088 pressure transmitter has superior measurement capabilities, can be used for almost any line pressure or tank level measurement.Zui standard 2088 low pressure transmitter Rosemont 0 to 1.5 psi, Zui high standard range of 0 to 4000 psi.Rosemount2088 pressure transmitter can also be used to measure the negative pressure range.
Two, work principle:
The diaphragm will transfer pressure to the polysilicon sensor, the sensor is filled with silicone oil or inert liquid.To gauge transmitter, sensor reference atmospheric pressure; the absolute pressure transmitter sensor reference pressure is a sealed vacuum reference source.In the process of pressure sensing diaphragm of the sensor, the diaphragm produces a small deformation, which gives the sensor Wheatstone bridge is a stress is applied, the Wheatstone bridge strain resistance, the resistance change is measured and converted into a digital signal processing for microprocessor.ASIC uses the electronic circuit 2088 pressure transmitter (ASIC) and surface mount technology.The electronic board receives the sensor film head digital signal and correction coefficient after correction and linearization of signal.The output circuit of the electronic board to complete the DAC output after an analog signal.The intelligent output circuit, colleagues with HART communication function, and can make the HART protocol control system or AMS communication equipment management system.
Three, widely used:
Suitable for almost all field values.Whether it is applied to the occasion, the silicon piezoresistive sensor, a dual chamber housing and a compact, lightweight design can ensure reliable, convenient and economical installation.
Fourth, measuring characteristics:
To ensure high reliability and high precision, at the same time the price is attractive.Rosemount2088 pressure transmitter has superior measurement capabilities, can be used for almost any line pressure or tank level measurement.Zui low standard quantitative range of 0 to 1.5 psi, Zui high standard range of 0 to 4000 psi.Rosemount2088 pressure transmitter can also be used to measure the negative pressure range.
