JSC «Electronstandart-pribor” model SSS-903M Gas Detector of hydrogen sulfide, combustible and toxic gases is intended for automatic and continuous monitoring of flammable, toxic and combustible gas levels. SSS-903 consists of Transmitter SSS (threshold device) and plug-in universal gas transducers PGU with electrochemical (PGU-E) , infrared (PGU-IR) and photoionized (PGU-P) sensors.
Transmitter SSS is the universal one-channel threshold unit intended for visualization of gas signals values receiving from plug-in gas transducers. Transmitter SSS has following output signals: 3 threshold relays and 1 “fault” relay, digital output (RS-485) and analog output 4-20 mA. Any HART-communicator device can be connected to Transmitter SSS via standard HART-connector for readout gas concentration values, threshold changing, zero set-up and sensitivity calibration in a field conditions.
Universal Gas Transducer PGU consists of PGU module and plug-in sensors either electrochemical, infrared or photoionized. PGU has integrated flash memory with adjust settings, which are read automatically when connecting to Transmitter SSS. Communication with Transmitter SSS is carried out by means of digital output RS-485. PGU sensor is fitted out by special protective filter providing the additional protection from dust and high ambient humidity.
Transmitter SSS body is made from stainless steel SS 316 mark and has explosion protection IP66 and intrinsically safe barrier level.
