Integrated temperature transmitter
Description
SBW series integrated temperature transmitter is the combination of temperature sensor and transmitter, in a very simple way to convert the temperature signal within the range of -200~+1600 ℃ into a two-wire system of 4~20mA DC electrical signal transmission to the display instrument, regulator, recorder, DCS, etc. To achieve accurate temperature measurement and control. Integrated temperature transmitter is a modern industrial site, scientific research institute temperature measurement and control update products, is a distributed system, digital bus system of the necessary products. 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 measuring accuracy and good long-term stability. The interior of the temperature module adopts epoxy resin pouring process, which is suitable for all kinds of harsh and dangerous places. Integrated design, simple and reasonable structure, can directly replace ordinary prefabricated thermocouple, thermal resistance. Mechanical protection IP65. Using thermocouple temperature change, can avoid the use of compensation wire, reduce the cost of liquid crystal, digital tube, pointer and other indicating functions convenient on-site timely monitoring. When the ambient temperature of the site is more than 70 ℃, the transmitter and the field display instrument can be installed by separation (isolation) explosion-proof grade: EXdIIBT4, EXdIIBT6, EXdIICT6. Protection grade: IP54 integrated temperature transmitter technical specifications
