The standard Pick-off Sensor are magnetic reluctance type. Each output is approximately 30 mV peak to peak at minimum flow. The frequency generated is directly proportional to the rotation of the Turbine Meter Rotor, or in other words, the flow rate. Different models of Pick-off Sensors are available according to the different areas of use such as standard, intrinsically safe, high temperature applications. Certification : II 1G/EEx ia IIC T6
