This service specializes in the custom design of Industrial Temperature Sensor Solutions to solve the most difficult of temperature measurement problems in challenging environments.

Experienced Wahl engineers are on-call to offer assistance with product design, material selection, drawings, and other considerations necessary to meet the specifications and demanding requirements of the process and eliminate unplanned downtime. Sensor and thermowell applications that demand rapid response times, feature high pressure ratings, or have vibration concerns are just a few of the issues that can be addressed with our custom made engineered temperature solutions.

Thermocouples in single, duplex, and triplex types are available in base metal and precious (Nobel) metal types, manufactured from mineral insulated cable with high purity 99.8% magnesium oxide insulation with stainless steel or specialty metal sheaths with diameters from 0.020" to 0.5". Thermocouples with accuracies up to AMS Special Limits of Error and beyond may be selected depending on the process requirements and working conditions of the installation.

RTD Sensor Assemblies are also available in mineral insulated construction in both 1/8" and 1/4" diameters. Internal connection leads are made of copper or nickel, insulated with High Purity magnesium oxide. Two, three, or four wire connections are available with accuracies up to 1/10 DIN standard.
