Thermometrics operates a fully integrated sensor manufacturing facility in Northridge, California. Every capability needed to produce, inspect, and calibrate a temperature sensor assembly — from raw MIMS cable to finished calibrated assembly — exists under one AS9100D-certified roof.
In-house CNC lathe and mill capability for thermowell, fitting, connection hardware, and custom adapter machining. Tolerances to ±0.001" on turned diameters. Materials: 316SS, 304SS, carbon steel, brass, Inconel, titanium, Hastelloy, and PTFE.
Cut-to-length, form, swage, anneal, and terminate MIMS thermocouple cable from 0.020" to 0.500" OD. All standard sheath materials. Hot-junction formation by TIG and resistance welding. Cold-end stripping and conductor identification per customer specification.
Wire-wound Pt100 element assembly on ceramic and glass mandrel. Lead attachment by silver soldering and resistance welding. 2-, 3-, and 4-wire configurations. Encapsulation in ceramic cement, glass seal, or PTFE shrink for moisture protection.
TIG welding for thermocouple junction formation, sheath closure, and connection hardware. Qualified welding procedures per AWS D17.1 for aerospace work. Vacuum brazing for hermetic application. Silver brazing for high-temperature joints. Weld inspection per visual and dye-penetrant methods.
NIST-traceable RTD calibration from −200°C to 850°C. Comparison calibration in liquid baths and dry-block calibrators against reference platinum resistance thermometers (SPRTs). Individual R vs. T tables issued with calibration certificates.
Thermocouple calibration from 0°C to 1100°C in tube furnaces against NIST-traceable reference thermocouples. EMF vs. temperature tables and polynomial deviation coefficients available. Type R, S, and B noble-metal calibration to 1480°C.
Insulation resistance measurement on MIMS assemblies per ASTM E585. 500V DC test between each conductor and sheath at room temperature. Results documented on traveler and included in calibration certificate where specified.
Repair, inspection, and recalibration of existing sensor assets. Visual inspection, dimensional measurement, and NIST-traceable calibration — with full documentation reissued. Aerospace-grade repair per AS9100D §8.5.6.
Standard thermocouple assemblies: same-day to 1 business day. RTD assemblies: 1–2 days. Complex MIMS or formed assemblies: 3 days. Machined thermowells: 3–5 days. Custom or FAIR-required orders: quoted individually. No minimum order quantity.
Thermometrics does not impose minimum order quantities on any product line. Single-piece orders receive the same quality and documentation as production runs. This is particularly important for aerospace programs requiring individual serial-number-tracked assemblies.
