Multipoint Sensors

A multipoint sensor allows the measurement of a temperature profile across a large area. Thermocouples or RTDs are arranged with measuring junctions at various points along a pipe, allowing the measurement of various points from a complete assembly. Many elements can be spaced along a probe.

This opens up possibilities for improved profiling in reactors, for example, where flow interference prevents inserting large numbers of individual probes. Multipoint probes can also be used to give a temperature profile where stratification of a tanks' contents may be of concern. JMS will custom design your assembly to give you the most accurate temperature measurement for your process.

The following information and/or drawing is needed to properly design your assembly.

• Thermocouple calibration or RTD type
• Outside diameter of pipe and pipe material
• Junction style of thermocouple
• Sensor material (Bare wire, 316SS tubing, or sheath material
• Overall length of the entire assembly
• Process connection
• Accuracy required
• Cold-end termination
• Maximum operating temperature

JMS will generate a drawing for your assembly.
