S120 Oil Vapor Monitor 4/5 LEDs indicate if pre-set alarms are reached, or if filters and sensors need to be serviced. The service indications start blinking 4 weeks before expiring and turn on permanently when a service is immediately required. Power Alarm Service Sensor Service Filter Technical Data General Data Measuring medium Compressed air, N2, CO2 (for other gases please contact us) Sample flow rate < 2 l/min, measuring gas is released to ambient Sample rate 1/sec Gas / Operating temperature -20 ... +50 °C Transport temperature -30 ... +70 °C Operating pressure 3 ... 15 bar(g) 0.5 ... 3 bar(g) (optional) 0.60 ... 1.07 bar(a) (ambient version only) Gas humidity < 40 % rel. humidity, no condensation Gas connection 6 mm quick connect UV lamp lifetime 6,000 working hours or 1 year, whichever comes first Electrical connection M12, USB, RJ45 Settings Various sensor settings can be performed through SUTO display units or through the related service software Housing material PC, Al alloy Protection class IP65 Dimensions 271 x 231 x 91 mm Weight 2.4 kg Approval CE Measurement Oil Vapor Measuring range 0.001 ... 5.000 mg/m³ (Based on 1000 hPa(a), 20 °C, 0 % relative humidity) Accuracy 5 % of reading ± 0.003 mg/m³ Resolution 0.001 mg/m³ Selectable units mg/m³ / ppm Sensor principle Photo ionization detector Pressure Measuring range 0 ... 16 bar(g) Accuracy 0.5 % FS Resolution 0.01 bar(g) / 0.001 MPa / 0.1 psi Selectable units bar(g) (default), MPa and psi (on request) Sensor principle Piezo resistive pressure sensor Dew Point (optional) Measuring range -100 ... +20 °C Td Accuracy ±1 °C Td (0 ... 20 °C Td) ±2 °C Td (-70 ... 0 °C Td) ±3 °C Td (-100 ... -70 °C Td) Resolution 0.1 °C Td Selectable units °C Td / °F Td Sensor principle QCM + Polymer Temperature Measuring range 0 ... 50 °C Accuracy 0.5 °C Resolution 0.1 °C Selectable units °C / °F Sensor principle NTC Signal / Interface & Supply Outputs / Interface Analog output 4 ... 20 mA, isolated Alarm output Relay, NO, 40 VDC,0.2A Digital interface Modbus/RTU (RS485) Modbus/TCP (Ethernet) & USB (only available for display version) Display (optional) 5” color touch screen with a data logger of 30 million measurement values Supply Power supply 24 VDC ± 5 %, 10 W Dimesions 170 mm 271 mm m91m
