System design
Sensing data
Detectable gas: NH3
Measuring range: 0-100 ppm
Calibration gas: NH3
4-20 mA: 4 mA=0 ppm, 20 mA=100 ppm
Wiring
Placement
The sensor must be placed 150-180 cm from ground level on a side wall or on a vertical surface at inhalation height. One sensor can cover an area of around 25-50 m2, but the design of the room and the areas where the gas can stop must be taken into account.
Cabling
Depending on the distance between the SENS-EX TG/AS-NH3-C sensor and the center, use a 3-core, 0.75-1.5 mm2, twisted-core cable with a gas-tight circular cross-section, max. resistance 25 Ohm/1000 m. Use the radial cabling principle between the center and the detector, introduce a separate cable for each sensor.
