Remote Head Kit 25m ST.R25M

ST.R25M - Sensor head remote connection up to 25 meters for SMART3G series - Sensitron

This option allows to have a remote sensor head for SMART3G gas detectors, with a maximum distance of 5 m.
The possibility to have a remote sensor head can be particularly useful when the gas detector should be installed in places difficult to reach to perform the periodical maintenance.
The gas detector is equipped with two extra electronic boards: a near board connected to the main board and a remote board connected to the sensing element. These electronic circuits guarantee the possibility to have a remote head up to 25 m. The 25 m cable is not supplied.

This option is only available when purchasing new gas detectors. Please specify when ordering.

Flameproof enclosure with the gas detector main board and a near board;
2 ATEX cable glands;
Remote head, composed by a flameproof enclosure with remote board and a stainless steel sensor head.
