Description

The CT-333 movable flange type temperature sensor features a flange and adjustable insertion depth design, allowing the probe insertion length to be adjusted according to different pipe wall thicknesses or installation depths, reducing the problems of excessive probe exposure or insufficient insertion. Protective sleeve materials include SUS304, SUS316, and the high-temperature durable SUS310, suitable for use in high-temperature or partially corrosive fluid environments. Probe diameter and length can be customized upon request. It is suitable for scenarios in industries such as chemical, pharmaceutical, food, and energy where frequent maintenance or adjustment of measuring point positions is required, and is particularly suitable for applications with varying pipe thicknesses, installation depths, or high requirements for equipment compatibility.
