The new generation of stationary gas detectors: RIKEN KEIKI SD-3

SD-3 Serie: stationäre Gasdetektoren

Robust housing construction enables use in an extended temperature range between -40 to +70°C SIL2, ATEX, IECEx, 4-20mA, HART, MODBUS, CE, IEC(EN), MED, IP66,67

The SD-3 series products are stationary explosion-proof gas detectors that can continuously monitor the surrounding atmosphere for flammable gases, toxic gases and oxygen. These detectors detect gas leaks and trigger an alarm if preset concentrations are exceeded. The detected gas concentration is converted and output in the form of a 4-20mA analog output and a digital HART output signal. Other output options include Modbus communication (RS-485) and the use of three relays.
