WZPK series armoured platinum resistance
WZPK series armoured platinum resistance has smaller diameter, is more flexible and has better vibration resistance than Fabricated type platinum resistance, and is suitable to install in the place that Fabricated type platinum resistance can not be installed. The WZPK series armoured platinum resistance our factory produce uses temperature measurement components of introduced platinum resistance. Thus, it has advantages of accurate measurement, sensitivity, short thermal response time, stable quality, long service life and so on. The outside protected case of armoured platinum resistance uses insulator which is made of stainless steel, and is filled with High-density oxide material inside. So, it has strong anti fouling property and Excellent mechanical strength, is suitable to be installed in harsh environments.
Armoured platinum resistance can measure temperature of -200～500℃. It can be used straightly in connection with copper wires and secondary instrument. For its good Electricity output characteristic, it can provide accurate input signal of temperature variation for displayer, recorder, regulator, scanner, data recorder and computer. It shall as per JB/T8622-1999.
The working principle of armoured platinum resistance: Resistance of platinum wire resistance varies with temperature. Display will indicate the temperature value corresponding the resistance value made by platinum wire resistance.
Main Technical Parameters
Allowable Deviation △t ℃
Note: “t” is absolute value of measured temperature of temperature-sensing element.
Generally refers to the room temperature, protective tube will not crack under static pressure. Test pressure usually use 1.5 times of nominal pressure. Actually, Allowance nominal pressure is not only related to material Of protecting tube, diameter and wall thickness, but also related to its structural style, installation method, placed-depth and the types, flow rate of measured medium.
Thermal response time
When temperature is under the step change, the input of thermal resistance changes to the time that 50% of the step change cost. It is called thermal response time, which is represented by T0.5.
Thermal resistance insulation resistance
The test voltage of the normal temperature insulation resistance can be any value of 10~100V DC. The ambient temperature shall be 15～35℃, and the relative humidity shall be no more than 80%. The normal temperature insulation value shall be no less than 100MΩ.The max electric current measured by armoured platinum resistance shall not be more than 5mA.
