SF6 measuring instrument 3-026-R115

concentrationbeamNDIR

The device even detects smallest SF6 concentrations and displays the current measuring values permanently. For the operating personnel it is absolutely necessary to know that no radioactive source is used. Therefore, no special measures must be taken during operation. The SF6 Air Sensor guarantees a quick reaction time. Furthermore, there is no cross sensitivity to moisture and background contamination and the measuring result remains constant. Parameters for warning messages and alarm tripping are freely configurable. Advantages & functions • measuring range: 0 up to 1,500 ppmV SF6 • high longtime stability • no maintenance and consumables are required • indication of the measured value via LCD on the front of the device • air pressure compensated • analogue and serial interface • warm-up time: < 2 minutes (run-up), reaching full specification after 15 minutes • response time: < 2 minutes • recommended monitoring range per Sensor: 250 m2 Technical data Weight : 0.25 kg Dimensions (W x H x D) : 80 x 150 x 60 mm Indication : directly via LCD Protection class : IP 41 Operating temperature : -10 to +40 °C Long-term stability of SO2 sensor : < ±2 % of measuring range final value / year Ambient moisture : max. 95 % relative moisture non condensing during operation Measuring accuracy : < ±2 % of measuring range end value Frequency : 0.16 Hz Power : 160 A m Operating voltage : 24 V DC Measuring range : 0 - 1500 ppm SF6 Measuring principle : NDIR (double beam)
