M18 Rotate Speed Sensor with 2 Output Terminals IP44 Magnetoelectric Diesel Generator Speed Sensor 50V Item Type: Diesel Generator Speed Sensor Material: Aluminum Alloy Operating Ambient Temperature: -30℃-120℃ Maximum Sensing Voltage: 50V AC Maximum Tightening Torsion: 49N.M Mounting Thread: M18 Output Signal: Switch Type Protection Levels: IP44 Linearity: 5 (%F.S.) Hysteresis: 5 (%F.S.) Repeatability: 0 (%F.S.) Sensitivity: 100Percent Introduction: This product is a magnetoelectric speed sensor mounted beside the flywheel of the engine. When the engine rotates, the speed sensor senses an AC signal whose frequency is proportional to the engine speed. The speed sensor is used in conjunction with a tachometer (not included) to measure the engine speed.
