Two wide longitudinal water draining grooves enhance excellent drainage capacity, and effectively prevent tire lateral slip on rainy and snowy land.
3D winding sipe and angle design sufficiently provide grip ability, ensures the block regidity and effectively prevent slipping on icy and snowy land.
Wide shoulder block design provide a remarkable handling and steering performance.
More silica compound greatly promote grip power on snowy land.
Crossed and single guidance pattern provide excellent drainage performance, combined with a great deal of transverse groove, greatly promote the grip performance on icy and snowy road.
Water absorbing hole design, effectively prevent the tire from slipping, knurling enhances the skid resistance during preliminary stage of tire.
An armored thermal resistor is a type of temperature sensor. When a substance changes its temperature, its resistance will also measure the temperature as it changes. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value. It is smaller than the diameter of the assembled platinum resistance and is easy to bend. It is suitable for installation in narrow pipelines and special occasions such as rapid response and miniaturization. It can automatically detect gases, liquid media, and solid surfaces within the temperature range of -200~600°C, and can be directly connected with copper wires and secondary meters. Because it has very good electrical output characteristics, Accurate input values ​​for displays, recorders, regulators, scanners, data loggers, and computers. Below, Yi Xian will give you a brief introduction to the purchase of attention.
Armored thermal resistors are made of a combination of metal maintenance tubes, insulating materials, and resistors. The resistor in the armored RTD is made of fine platinum wire on a platinum-rhodium thermocouple ceramic or glass crucible. The lead is usually steel wire or silver wire.
Precautions:
The connection wire between the RTD and the display instrument should be insulated copper wire. The thermocouple compensation wire should not be used. The resistance value of the copper wire should be matched according to the data showing the technical conditions of the instrument. It is usually 2 to 50. The resistance value of the wire can be adjusted with a DC equalization bridge.
It is not possible to use a thermal resistance in parallel with two visualization devices, as long as the dual thermal resistance can be used with two visualization devices.
Thermal resistors and their accessories must be stored in the center of the tungsten/tungsten thermocouples that are not subject to vibration or collision when not in use. The most suitable storage site conditions are: ambient temperature 10-35 °C; relative humidity can not be greater than 80%; ambient air should not contain substances that may form thermal resistance parts corrosion.
When wiring the thermal resistance, open the junction box first and then wire it. The wiring method is usually two-wire system and three-wire system. The advantage of the three-wire connection is that it can prevent the bimetal thermometer from showing the indication error of the meter due to the resistance value of the connecting wire.
Most of the thermal resistance of the sensor is about 120mm in length. When selecting the insertion depth of the thermal resistance, it should be considered that the thermal resistance can only measure the uniformity of the measured medium in the proximity of the sensor.
The maximum operating temperature of the RTD and the working pressure cannot exceed the rated value of the RTD. If the RTD is to be used in a corrosive medium, a maintenance tube made of stainless steel should be used.
With flexible performance, armored thermal resistance can be bent in any direction except the head. Therefore, it is suitable for more complicated structures and has good vibration and impact resistance.
