WZC series assembly-type thermal resistance thermometer detector
WZC series assembly-type thermal resistance is used as a sensor to measure temperature, usually matched with display instruments, recording meter and electronic computer. It can directly measure temperature from -200oC to 500oC of liquid, vapor, gas medium and solid surface during various production processes. Our factory product two categories assembly-type, unified design type thermal resistance: Pt100 as per IEC and Cu50 as per Professional norm degree. In addition, the device has the advantages of simple assembly, convenient replacement, pressure spring type temperature sensing element, good anti-vibration, wide measuring range, high mechanical strength, good pressure durability.
Thermal resistance measures temperature using the property that its resistance value changes with temperature. Temperature sensing element of thermal resistance is made of metal wire twining insulation in pairs equably. When there is temperature gradient in measured medium, the measured temperature is average temperature of the medium where the scope of sensing element in.
Junction box, protective tube, insulated casing, termals and thermal electodes form a basic structure of assembly-type thermocouple, with a variety of installation of fixtures.
Main technical parameter
Normal temp insulating resistance
When environment temperature is 15～35℃, relative humidity is no more than 80%, testing voltage is 10～100V(DC), the insulating resistance of electrode and outer tube is ≥100MΩ.
Range and accuracy
Thermal resistance type
WZC type Cu resistance
Note: “t” is absolute value of measured temperature of temperature-sensing element.
Ratio of resistance value of thermal resistance’s sensing element when in 100℃（R100） and when in 0℃(R0):（R100/ R0）
Thermal response time
When the temperature appear step change, the thermocouple output variation is to the equivalent of 50% of the change, The time required is called the thermal response time “T”
The nominal pressure of the thermocouple
Generally speaking, it is the static outside pressure which the protection tube can withstand without being broken in the room temperature. In fact, allowing working pressure is not only related to the protection tube material, the diameter and wall thickness, it is also related to its structure, the installation method, the into depth, the measured flow rate to its structure, the installation method, the into depth, the measured flow rate and the type of media.
