Thermometrics multi-point thermocouple assemblies house multiple independently calibrated thermocouple junctions within a single protection tube or MIMS sheath — providing a temperature profile at multiple depths through a vessel, tank, catalyst bed, or kiln from a single process nozzle.
| Parameter | Specification |
|---|---|
| Number of Junctions | 2 to 12 independent junctions standard; up to 20+ custom |
| Junction Spacing | Customer-specified; equal or variable pitch |
| TC Types | K, J, T, E, N, R, S — same or mixed types within assembly |
| Junction Style | Grounded or ungrounded; all junctions in one assembly |
| Construction | MIMS multi-conductor cable or ceramic multi-bore tube |
| Sheath OD | 3/8" to 1" (MIMS multi-conductor); custom for ceramic tube |
| Sheath Material | 316SS · Inconel 600/625 · Ceramic (alumina) |
| Process Connection | NPT threaded · Flanged · Compression · Van Stone |
| Total Insertion Length | 6" to 240"; custom |
| Termination | Individual lead wires · Multi-pin connector · Terminal head |
| Calibration | Per-junction NIST-traceable certification on request |
To quote a multi-point assembly, provide: total insertion length, number of junctions and their depths from the process connection, TC type, junction style, sheath material, process connection type, and termination style. Thermometrics will confirm the sheath OD and conductor bundle required to accommodate the number of junctions specified.
