SO-121M Ice detector CO-121M.

SO-121M

For order is possible effectively delivery of any quantity.
Ice detector SO-121M (SO121M, SO-121-M, SO 121 M, SO 121M)
 
Ice detector SO-121M is designed to alert the presence of icing conditions and the formation of the following signals:
- A signal of "ice" - a device for signaling the crew;
- The signal "PIC" - on and off anti-icing system;
- A signal of "BAR" - in the on-board recording equipment parameters;
- A signal of "RI" - voice and informant.
 
Technical characteristics of equipment alarms icing SO-121M:
 
Product production in 2012;
Signaling icing used on aircraft (airplanes and helicopters), both domestic and foreign production;
The composition of the unit SO-ice detector sensor alarm 121VM includes DSL-40T (DSL-40TV - depending on the version), an electronic transducer PE-11M, a frame assembly of the RM-5 and RM-6 (depending on the version);
The sensor DSL-39MT ice discharge from the bracket by hot air, but with a vibrator - with an electric heating;
Discharge of ice from the bracket sensor DSL-40T, in contrast to DSL-39MT sensor is electrically heated. Sensors DSL and DSL-40T-40TV different type of connector: DSL-40T - Connector 2RMGD, and DSL-40TV - SNTS23 connector;
The frame assembly of the RM-5 is designed for installation of a converter of PE-11M, and the frame assembly of the RM-6 - two converters PE-11M.
Versions of the ice detector device SO-121M and its compounds are listed in Table 1;
