S300 Series Dust Monitors   Overview The S31X (intrinsically safe (ATEX) models utilise Sintrol’s S300 Series unique detection principle. Like all S300 Series Dust Monitors, S31X models have Automatic Range setup, i.e. do not require manual adjustment. Automatic drift compensation is standard in all five models. Self diagnostics (self Zero check and self span check) standard in S315X model. The five models range from filter bag leak detection, and trend monitoring to emission- or stack-monitoring applications. Further information is available from Sintrol or your local distributor.       Technical Specification     Process Conditions: Temperature: Max. 300°C Pressure: Max. 2 bar Humidity: 95% RH or less (non-condensing) Input surge protection: Under 20 kA pulses limited to 90 V Damping time constant: 10 to 180 seconds Output signals: isolated 4–20 mA 2 x relay 5 A, 24 V AC or DC Ambient conditions: Temperature: –20 to + 45°C Humidity: 95% RH (non-condensing) Vibration: 5 m/s2 or less Materials: Sensor rod: stainless steel Sensor rod length: Up to 1.0 m Insulation of sensor: PEEK Enclosure /casing: Die-cast Aluminium Power Supply: 115 VAC or 230 VAC or 24 VDC External fuse requirement: two 200 mA slow (T) fuses Power consumption: 3 W Wiring connections: – External mains connector – DIN rail connector for output signals – PG11 EMC-type cable glands for signals Weight: Sensor 2.0 kg Junction box 3.0 kg Signal processing unit 1.6 kg Cable: 4-core screened low capacitance cable e.g. Belden Inc.
