MPTC-04 Multipoint GuideTube Style Thermocouple/RTD – Temperature is a critical parameter in all systems, regardless of the process. In every heating or cooling system, variations occur throughout the medium—temperature gradients always exist. In many applications, measuring temperature at a single point is sufficient, as minor variations often have little impact. However, in certain applications, uniform temperature measurement is essential to ensure product quality. TempoTech’s Free Hanging style Multipoint temperature sensors provide accurate measurements at multiple points along a single sensor assembly. Free hanging design is inexpensive compare to guide tube and heat sink guid tube and simple to maintain on site as thermocouples are installed inside the tubes free hanging ann individual thermocouple can be removed without needing to remove other thermocouples. . They are widely used in complex processes where precise temperature control is necessary such as Distillation and Separation Processes, Heat exchanger temperature profiling , Polymerization and Chemical Process, Reactor Temperature, Distillation Columns,Crude Oil Desalting, Fluidized Catalytic Cracking, Visbreaking Units and many more. These sensors are specifically designed for applications that require high-precision temperature monitoring across a wide temperature range. Multipoint sensors are constructed using MGO-PAC thermocouples housed within protective tubes, with sensing elements placed at different points inside the tube. TempoTech offers multipoint sensors in a variety of materials to meet diverse process requirements.

Application Note

MPTC-04 Multipoint GuideTube Style Thermocouple/RTD – MPTC-04 Multipoint Guide Tube Style Thermocouple/RTD is designed for accurate temperature measurement at multiple points within a single assembly. It is ideal for industrial processes where precise monitoring of temperature variations is essential for maintaining safety, efficiency, and product quality.

In most process systems, temperature distribution is not uniform and varies due to operating conditions, materials, and system design. While single-point measurement may be sufficient in some cases, applications with significant temperature gradients require monitoring at multiple locations to ensure reliable control and consistent performance.

The MPTC-04 multipoint temperature sensor uses a guide tube design that allows multiple sensing elements (thermocouple or RTD) to be positioned at different depths. This construction provides better mechanical protection, ease of maintenance, and flexibility in replacing individual sensing elements without removing the entire assembly.
