Resistance (RTD) temperature assembly for use in existing thermowells or machinery • Thread connection • ASME-style, without thermowell • -40…+600°C / +1100°F The OPTITEMP TRA-S50 is a threaded RTD sensor assembly without thermowell. The temperature assembly can be mounted to existing thermowells or machine housings by a thread connection or union nut. The RTD is suitable for temperature measurement of liquids, gases and steam up to +600°C / +1100°F. However, it cannot be operated without thermowell. The OPTITEMP TRA-S50 features a modular design with a threaded neck tube that can be exchanged easily, even under operating conditions. This makes the temperature assembly very flexible. If it has been damaged from the outside, servicing can be carried out without process shut down. The resistance temperature device can be combined with most thermowells. It is available with ATEX and IECEx approvals. Product highlights • Temperature measurement of liquids, gases and steam • Modular design: Flexible union neck tube or threaded DIN neck tube for easy exchange under operating conditions • Without thermowell, sheath material: 1.4404 / 316L • Also suitable for installation into existing thermowells • Standard or customised lengths • Different connection heads available (IP54…IP68) • With optional temperature transmitter • Available as intrinsically safe: ATEX, IECEx • Typical applications • For installation into existing thermowells as well as bearings or similar machinery in various industries: • Chemical and petrochemical • Oil and gas • Power generation • Machinery and apparatus / OEM • Iron and steel • Pulp and paper
