Product Overview:
WZ Thermal Resistance as the sensor for measuring temperature, often matches with display instrument, recorder and electronic regulator for use. It can directly measure the surface temperature of the liquid, steam and air medium from -200ºCto 500ºC as well as the surface temperature of solid during productive process.
Features:
·Imported temperature-sensing element stable and reliable function
·High machanical strength, good pressure resistance
·High measuring accuracy
·Compensating wire needless, convenient and economical

Remark: The "t" in formula is Absolute value of measured temperature of temperature sensing element.
Thermal Response Time
When there is a step change in temperature,The time required for the output of the thermal resistance to change to 50% of the step change, It's called thermal response time, with T0.5 said.

Thermal resistance Nominal Pressure
Generally refers to the external pressure (static pressure) that the protective tube can withstand at this working temperature.The allowable nominal pressure is not only related to the material, diameter and wall thickness of the protective tube, but also to its structure, installation method, placement depth and the flow rate and type of the measured medium.
Thermal resistance Minimum Placed-depth
lmin=l +15D
lmin-Minimum Available Placed-depth
L -Temperature sensing element length
D-Outer diameter of protective pipe
Insulation Resistance
The test voltage of insulation resistance at room temperature can be 10 ~ 100V dc arbitrary value, the ambient temperature in the range of 15 ~ 35ºC, the relative humidity should not be more than 80%.Cold insulation resistance shall be not less than 100 m Ω.
