  • Application

    The Omnigrad T TST187 RTD thermometer range covers a wide variety of market needs worldwide. Typical applications can be found in the chemical and pharmaceutical industry, pulp and paper, waste water and food industry. It is widely used in vessels and pipes where a reasonable response time is required.

    Function

    The Omnigrad T TST187 RTD thermometer assembly includes a replaceable inset, in mineral insulated sheath with a G½" process connection. The head transmitter (DIN 43729 Form B) is thermal decoupled via a extension neck. The inset is available either with flying leads for head transmitter mounting or with terminal block.
