In the technical advice we solve, about the temperature transmitter selection more, the technical staff of the temperature transmitter selection of the technical points of the overall summary. To provide customers with full technical support.
First, according to the temperature measurement range, select the corresponding RTD temperature transmitter, thermocouple temperature transmitter or thermistor temperature transmitter.
Secondly, for the choice of connection. General conditions can be selected threaded connection, the following occasions should be selected flange connection: in the equipment, lined pipes and non-ferrous metal pipeline installation; crystallization, scarring, clogging and strong corrosive media: flammable, explosive and highly toxic media.
Third, based on the use of different environments, the need for the following principles for the selection of junction boxes for temperature transmitters.
Better conditions in the place: you can choose ordinary temperature transmitter junction box.
Wet or open places: need to have waterproof effect of splash-proof, waterproof temperature transmitter junction box.
Flammable, explosive places: from the safety of the working environment, must choose explosion-proof temperature transmitter junction box.
Fourth, for the temperature transmitter probe length selection. Temperature transmitter insertion probe length should be selected to detect the element inserted into the measured medium temperature change sensitive and representative of the position as a principle. Temperature transmitter probe material hard not lower than the equipment or pipe material. If necessary, the temperature transmitter can be described as a protective sleeve.
With the enhancement of technology, temperature transmitter applications are more and more, such as petroleum, chemical, chemical fiber; textile, rubber, building materials; electric power, metallurgy, medicine; food and other industrial fields on-site temperature measurement process control; computerized measurement and control systems and so on can not be separated from the monitoring of temperature. Temperature transmitter can also be used in conjunction with other instruments.
