Principle and application of intelligent precision heavy duty industrial pressure sensor based on network

 Recently, the Usa Honeywell (Honeywell), the corporation has launched a series of PPT, PPTR series and PPTE enables networking of intelligent precision pressure sensor. These sensors are pressure-sensitive resistors, a/d converters, microprocessors, memory (RAM, e 2PROM) and interface circuit set in one particular, not merely to meet performance targets, but additionally tremendously facilitates the user. These merchandise are widely made use of in market, environmental monitoring, automation, medical equipment and also other fields.
two PPT, PPTR series efficiency of pressure sensor

(1) PPT heavy duty industrial pressure sensor
applied steel diaphragm, with RS-232 interface, sensor distance not more than 18m, for measurement rapid changes or slow changes of numerous not flammable, and no corrosion sex gas or liquid of stress (that table stress), and stress poor and also the absolute pressure, measurement precision as much as ?? 0.05% (complete range Shi of typical worth), and past of integrated stress variable sent device Supreme only reached ?? 0.1% of precision. PPTR items with RS-485 interface, transmission distance of as much as thousands of meters, it uses stainless steel diaphragm and measurement of corrosive liquids or gases, measurement accuracy is 0.1%.
(2) it belongs to sensor networks. Constitute a global network can figure out when each sensor address, group and device identification quantity ID address, can comprehend between the sensor along with the sensor together with the program of information exchange and sharing of resources, customers can obtain any sensor information over the network and to set the parameters with the sensor, set the parameters stored in E2PROM.
(3) output after calibration, the pressure and digital to analog, it's a precision digital pressure sensor plus a typical analog high temperature pressure sensor
to simulate continuous adjustable output voltages in the range of 0~5V, can be utilized as standard pressure source. Users without having a host to access to analog output.
