Integrated temperature transmitter
Description
SBW series integrated temperature transmitter is the combination of temperature sensor and transmitter, in a very simple way to the temperature signal within the range of -200~+1600 ℃ into a two-line system 4~20mA DC electrical signal transmission to the display, regulator, recorder, DCS, etc. Realize accurate measurement and control of temperature. Integrated temperature transmitter is the updated product of temperature measurement and control in modern industrial site and scientific research institutes. It is a necessary product of distribution system and digital bus system. Integrated temperature transmitter features ultra-small (module φ44×18) integration, universal strong two-wire system 4~20mA DC output. Long transmission distance, strong anti-interference ability. Cold end, temperature drift, non - linear automatic compensation. High measurement accuracy, good long-term stability. Epoxy resin casting process is used inside the temperature module, which is suitable for use in all kinds of harsh and dangerous places. Integrated design, simple and reasonable structure, can directly replace common assembled thermocouple, thermal resistance. Mechanical protection IP65. Thermocouple temperature change, can avoid the use of compensation wire, reduce the cost of liquid crystal, digital tube, pointer and other indicators convenient on-site timely monitoring. When the field ambient temperature is >70 ℃, the transmitter and the field display instrument can be separated (isolated) type installation explosion-proof grade: EXdIIBT4, EXdIIBT6, EXdIICT6. Protection grade: IP54 integrated temperature transmitter technical specifications
