The JC2M Ultrasonic Level Switch are manufactured in Polyphenylene Sulphide (PPS) for corrosion resistance inmost liquids. This range of sensors can be mounted in any position in a tank using either a 1-in. thread availablein BSPT and NPT thread forms. A thread is provided on each side of a hexagonal boss to allow either external orinternal / pole mounting of the sensor.Comprising a one piece moulded body with an integral pcb, the JC2M level switch is factory sealed and suppliedwith a 6.5 ft. (2 m) flying lead for customer connection.The JC2M switch is designed for high or low level alarm duties to give a voltage free contact output for alarmsignalling or as part of a pump control system.OPERATIONThe moulded body contains two piezo-electric crystals, one each side of a gap at the tip of the sensor. An ultrasonicsignal is transmitted from one crystal into the gap, but if there is air or gas in the sensor gap then the signal is notreceived by the other crystal. However, if there is a liquid present, the signal will be transmitted across the gap andthe integral electronics will switch the output circuitry to signal the presence of a liquid.
APPLICATION
• Low level alarms in header tanks
• Pump control duty in feeder tanks
• High and low alarms in storage tanks
• Level and pump control in storage tanks
• Small or thin wall tanks
• Bund level detection• Steering gear oil
