Probe
On TR 25 the measurement probe is constituted by a non replaceable mineral insulated insert (MgO) .
The insert length is available in the most commonly used dimensions or can be personalized by the customer
within a range of values (refer to "Sales Structure" at the end of the document).
Although the wiring diagram of single Pt 100 is always supplied with 4 wires configuration, the connection of
a trasmitter can be executed with 3 wires as well, by avoiding to connect whichever of the terminals.
The use of a TR 25 with standard lengths ensures fast delivery times; this allows our customers to reduce the
amount of spare parts to be kept on stock.
