Product Overview:
WR Thermocouple as the sensor for measuring temperature, often matches with display instrument, recorder and electronic regulator for use. It can directly measure the temperature of the liquid, steam and air medium from 0ºCto 1800ºC during productive process.
Features:
·Imported temperature-sensing element stable and reliable function
·High machanical strength, good pressure resistance
·Wide measuring range, high measuring accuracy

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.

Thermocouple 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.
