RTD Thermometer omnigrad TST11

C96EV100.CDR

Straight Thermowell

Reduced Tip Thermowell Fast response

Description TST11 RTD thermometer assembly includes a replaceable single or double Pt100 inset, in mineral insulated cable, which can be selected between standard or glass version (for high vibration level application). From the TET family, the inset is available either with flying leads for head transmitter mounting or with terminal block. The terminal head can be selected from a wide choice of standard items (see the Order key or TA20 Technical Information for more details). A wide selection of process connections, thermowell diameters and materials are available.

The thermowell can be delivered with a reduced tip for fast response time (using 3 mm insets). Application TST11 RTD thermometer is particularly suited to many light or medium duty applications either in vessels or in pipes. Typical application can be found in the chemical and pharmaceutical industry, pulp and paper, waste water, food and everywhere a reasonable response time is required coupled to a standard mechanical resistance.

For inset replacement see Technical data. Accuracy statement is referred to the replaceable inset only as defined by IEC 751 without any protecting thermowell which may introduce thermal drift due to process connection heat dissipation in conjunction to short immersion lenghts. For a correct temperature measurement the thermowell immersion length must be 20 times its diameter. Shorter immersion lengths can be supplied but the thermometer requires an external (process connection and connection head) thermal insulation. ! Contemporary selection of terminal block and built-in transmitter is allowed with TA20D head only.
