  • Application

    The Omnigrad T TST487 is a general purpose RTD thermometer particularly suited to many light and medium duty applications either in vessels or pipes. It can be applied where pressure and temperature are not extreme and where the performance/cost ratio is very important.


    The Omnigrad T TST487 RTD thermometer assembly includes a single Pt100 insulated probe and a terminal head. The process connection is threaded G ½".

    The inset is available either with flying leads for head transmitter mounting or with terminal block.
