OBAI-WZ Armored thermal resistor
Product Related Description
Product Overview
OBAI-WZ armored thermal resistance uses the characteristic that the resistance of a material changes when its temperature changes to measure temperature. The heated part of the thermal resistor (temperature sensing element) is made of fine metal wires evenly wound around a frame made of insulating material. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium layer within the range of the temperature sensing element. Usually and display instruments, recording instruments, computers, etc.
Main Features
♦Short thermal response time, reducing dynamic errors
♦Can be bent for installation and use
♦Wide measuring range
♦High mechanical strength and good pressure resistance
♦Imported temperature sensing element, reliable and stable
