CT-325 Connection Pipe Thermometer

Sturdy installation, customizable and flexible temperature sensors

The CT-325 is a tubular temperature sensor with a standardized design that allows for direct mounting to system interfaces via tubing. It is suitable for long-term, stable installation in piping or equipment structures for temperature monitoring. In addition to standard specifications, the sensing element, length, and material can all be customized.

Description

The CT-325 uses a pipe-connected mounting system, providing a stable installation interface and excellent temperature measurement stability, making it particularly suitable for long-term monitoring of piping systems, fluid lines, and equipment interfaces. Standard products include common thermocouples and platinum resistance thermometers, and offer a variety of protective sheath sizes and materials, which can be customized to meet site requirements.
