SMART 3-R

The SMART 3-R detector from Sensitron is ideal for applications in light industry and machine rooms, with a buzzer and LED indicator providing rapid alert to the presence of explosive, toxic and refrigerant gases.

Designed for machine rooms, laboratories and unclassified areas, the Sensitron SMART 3-R detector provides detection of explosive, toxic and refrigerant gases in safe (unclassified) areas.

With a 4-20 mA output, an RS485 communication bus and a 3-relay board, the circular LED indicator on the front displays the status of the instrument and an internal buzzer is activated in the event of a fault and/or alarm.

The instrument is controlled and calibrated via a keypad with STS/CKD+ display, with a protection rating of IP42. On request, the SMART 3-R can be supplied in a version with an additional remote head and a 5m 6-pole cable included.
