They can measure temperatures of liquid, steam,gas and solid in producing. Characteristics are shock resistant, high-temperature resistant and long life.Used for temperature measuring and automatic controlling in scope from -200 to 1600oC.Model and specification:TypeCodenameMeasurerange (ºC)ClassAllowable deviation t (ºC), the greater one of twoSpecificationlengthKNickel chrome-nickel sillicon

The insertion depth accord with actual need. Theinstallation of sensor maintain a position as vertical as possible, but in the case of flowmeasurement must install reverse tilt. If you need fix sensor, the container wall can be opened a fix larger hole than the sensors installation thread diameter, install the sensor fixed on the container with the nut attached. When the measured object is non- gas or liquid, the temperature sensor make some close contact with the measured object, in order to improve response speed and reduce the transmission error.If the thermocouple output wire need lengthen, you should use the relative thermocoupleompensation wire with the same polarity, and then connect with the secondary meter. Sensor wireor compensation wire should directly connect to the secondary meter connecting terminal, to avoid the use of ordinary wire, otherwise the error will be. Bending connection as little as possible to extend the use time, frequent bending sensors must be designed for.
