1. LV850 LEVEL SENSOR y NOTES LV850 LEVEL SENSOR 1 Description Level Sensor LV850 is suitable for liquids with low relative dielectric constant e g oil Units come with Minimum and Maximum selector switch It operates on the principle of electrical capacitance changes arising when an electrode surrounded by air is immersed in the medium e LED status display e Selection of minimum and maximum function by changeover switch Minimum switching Normally the sensor is immersed and the green LED indicates As the level drops below the sensor the green LED extinguishes Maximum switching Normally the sensor is not immersed and the green LED indicates As the level rises above the sensor the green LED extinguishes e In the event of a short circuit in the load circuit the green LED will extinguish and the red LED will flash Minimum Maximum switch position 1 switch position 2 LED LED medium level transistor output medium level transistor output green red load o Q LV850 LEVEL SENSOR 2 Technical Data Temperature range 20 C to 130 C 4 F to 266 F short time to 150 C 302 F Ambient temperature 20 C to 85 C 4 F to 185 F Pressure resistance max 25 bar 367 5 PSI Response delay approx 0 1 s Degree of protection IP 65 Input voltage DC 9 36 V Option metal coupling for pipe extension see fig 2 if the sensor is to be used as an immersion sens2. 7 Increase the level until the Level Sensor is immersed in the medium 8 Minimum Sensor e Turn the potentiometer screw E to until the LED green extinguishes Then slowly turn to until the LED indicates Adjust the screw a further full turn to to compensate for any tolerance 9 Maximum Sensor e Turn the potentiometer screw E to until the LED green extinguishes Then slowly turn to until the LED indicates Adjust the screw a further full turn to to compensate for any tolerance 10 Replace and tighten the cover C or the metal coupling option 11 Replace and tighten the cable gland nut PG7 The Level Sensor is now connected adjusted and ready for operation 5 Operating Difficulties Problem The Level Sensor fails to operate correctly Solution The surface of the sensor probe should be carefully cleaned from inside the container LV850 LEVEL SENSOR y NOTES WARRANTY DISCLAIMER OMEGA ENGINEERING INC warrants this unit to be free of defects in materials and workmanship for a period of 13 months from date of purchase OMEGA s Warranty adds an additional one 1 month grace period to the normal one 1 year product warranty to cover handling and shipping time This ensures that OMEGA s customers receive maximum coverage on each product If the unit malfunctions it must be returned to the factory for evaluation OMEGA s Customer Service Department will issue an Authorized
