WRNK series Armored thermocouple Has many advantages of high pressure resistance, bending, thermal response time fast and durable, it and industrial assembly type thermocouple, as a measurement of the temperature transmitter, and usually display instrument and record instrument and electronic regulator supporting the use, at the same time as the temperature sensing element assembly type thermocouple. It can directly measure a kind of production process from the 0~1300 temperature range of liquid, steam and gas solids and surface temperature.

Two, structure principle:

WRNK series of <strong> armored thermocouple</strong> works, two different components of the conductor ends by welding, forming a loop direct temperature measuring end called the working end, the terminal end is called the cold end, also called the reference terminal. When the temperature difference between the working end and the reference end, will produce thermal current in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the.

The thermocouple electromotive force will increase with the increase of temperature measuring end, only the size of Thermal EMF and thermocouple conductor material and the temperature difference between the two ends, and the length and diameter of independent power pole.

WRNK series of <strong> armored thermocouple</strong> structure, is composed of a conductor, high insulation, magnesium oxide coat 1Cr18Ni9Ti stainless steel protective tube, one drawn by many. The product is mainly composed of armored thermocouple junction box, terminal and sheathed thermocouple components of the basic structure, and with various fixed device. Armored thermocouple type insulation shell and then two.

Three, main features:

The thermal response time, reduce the dynamic error;

Flexible installation;

Large measuring range;

High mechanical strength, good pressure resistance;

Four, technical parameters:

IEC1515

GB/T16839-1997

JB/T5582-91

Nominal pressure thermocouple: generally refers to the static outer protective tube can withstand working temperature and pressure rupture.

Thermocouple: minimum insertion depth should be not less than 8-10 times the diameter of the protective sleeve (Frederick product exception)

Insulation resistance: when the ambient air temperature is 15-35 DEG C, relative humidity is less than 80% when the insulation resistance is more than 5 megohm (voltage 100V). With the splash proof junction box of the thermocouple, when the relative temperature is 93 + 3 DEG C, the insulation resistance of more than 500 billion euro (voltage 100V)

The insulation resistance of high temperature thermocouples under high temperature, the thermal electrode (including double type) and the insulation resistance between protection tube and double heat electrode (per meter) should be greater than the value specified under the table.

Armored thermocouple at ambient temperature for 20 + 15 ~ C, the relative humidity is not more than 80%, the test voltage is 500 + 50V (DC) insulation >1000 resistor between.M electrode and outer tube.
