WORKING PRINCIPLE The purpose of the rotary paddle level switch is to detect the presence of solid/powdery material in most kinds of tanks, bins and containers. The unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at RPM. When this paddle rotation is impeded by material, surrounding the paddle, motor will stall and cause the Micro-switch to change state (indicating an alarm or control). 1 Rugged sealing ring prevents dust from infiltrating the housing body along the...

WORKING PRINCIPLE & TORQUE ADJUSTING CONTROL SWITCH WORKING PRINCIPLE 1. A synchronous turning motor indicates the tank or container’s material isn't obstructing the paddles,C & L [COM & NC] are connected. 2. When the material is obstructing the paddles, C&L [COM & NC] are disconnected, C&H [COM & NO] are connected and the motor's current is cut off. 3. When the material drops away from the paddles and the motor starts again C & L [COM & NC] connect and the cycle has begun once again. TORQUE ADJUSTING MECHANISM AND WIRING 1 Do not tamper with the spring as it may cause the Rotary Paddle to...

MOUNTING EXAMPLES Regular models such as the SE11should be installed directly on the tank side. Mount at a 35° angle the blade through the tank opening or hole sliding the blade in first. * The SE170 series minimum hole size should be 95mm in diameter. The scimitar model is directly installed on the tank wall method as shown below. (Assuming an arc-shaped tank with a 3/4 "connection) and then screwing it tight. INJECTION MOLDING MACHINES Injection Molding Machine usually require the SE38. Install the Rotary Paddle through a 20mm diameter hole on the tank/silo. Remove the paddle from the...

INSTALLATION NOTICES 1. Side mount the sensor at a downward angle of 15° ~20° to decrease the material inflow impact. 2. For high temperature application (more than 70°C), please use the SE149 Series. 3. For SE110~SE140 using a 1" inlet, please apply the scimitar model and screw directly. 4. For SE130, SE146 series have flexible and extendible shafts. 5. Please ensure the lead wire enters the housing from the bottom and the nuts are fastened to secure the device.
