Absolute pressure transmitter honeywell, China-Technology (certification), absolute pressure transmitter

 Many different types of transmitters, in general, is a signal emitted by the transmitter to the secondary instrument secondary instrument display the measured data. The physical measuring signal is converted to a standard or common electrical signal output or device capable of communication protocol mode output. Generally divided into: temperature / humidity transmitter, pressure transmitter, differential pressure transmitters, level transmitters, current transmitter, power transmitter, flow transmitter imported absolute pressure transmitters, weight transmitters. Two-wire advantages: 1, less susceptible to parasitic thermocouples and pressure drop along the wire resistance and temperature drift, can be used very cheap finer wire; can save a lot of cable and installation costs; 2, when the current source output resistance is enough large, the magnetic field sensor coupled to the voltage intelligent wire loop absolute pressure transmitters, will not have a significant impact, because the current source of interference caused by small, usually using twisted pair can reduce the interference; three wire and four wire must be shielded and the shielding layer shielded cable should be properly grounded. 3, capacitive interference can cause the receiver to the resistance of the error, for 4 ~ 20mA two-wire loop, the receiver resistance typically 250Ω (sampling Uout = 1 ~ 5V) that resistance small enough to produce significant errors absolute pressure transmitter device, therefore, can allowed wire length longer than the voltage telemetry system; 4, each time a single display device or recording device in absolute pressure transmitters for access honeywell wire length ranging between different channels, not because of the length of the wire ranging between accuracy, decentralized collection, decentralized capture advantage is: decentralized collection, centralized control .... 5, 4mA to zero level, so that the judge open and short circuit or sensor is damaged (0mA state) is very convenient. 6, two-wire output port is easy additional twelve lightning protection and surge device, is conducive to safe mine explosion.
