PANAM PTWT threaded thermowells protect thermometers, RTDs and thermocouples from the process medium and allow the sensor to be removed while the system stays closed. They are machined from solid bar stock (hexagonal bar for stainless steel, round bar for other materials) with straight, stepped or tapered shank.
Process connections follow ISO 228-1 and ASME B1.20.1, instrument connection is 1/2" NPT (F), 1/2" BSP (F) or M20 x 1.5 (F). Materials are available according to NACE MR0175 / ISO 15156, with material certificates, hydrostatic test, dye penetrant, X-ray, hardness test and wake frequency calculation to ASME PTC 19.3 on request.
