Flotation Sensor Installation
| Flotation Sensor - wiring | |
|
Flotation sensor wiring is pretty straightforward. There are only two wires. The switch in the sensor is normally open. To make an effective NPN switch one wire is connected to ground and the other to the input of the control. To make a PNP connection, one wire is placed to the supply voltage (usually +24VDC) and the other wire is connected to the control input. It is strongly advised not to wire AC or voltages higher than 24V to the sensor because of the presence of liquids, an electrical hazard might exist. |

 |
A PVC "extender" can be used to position a floatation sensor at the desired internal level. Caution should be used because internal tank turbulence can cause breakage of the extender. Excessive turbulence may mean that an alternative non-contact method such as ultrasonics is required. |

| Warning: EMS products are not designed to be used as the sole element in critical systems such as personal safety or life dependency. These systems should always be designed with redundancy. |

EMS manufactures and supplies low cost sensors and low cost controls for process automation and industrial applications. EMS provides application assistance to insure that a particular sensor or technology is best suited to an application. EMS provides products and services to all segments of the process control industry. OEMs, system integrators, engineering firms, distributors, end users, product manufacturers, and system designers. We supply inductive proximity sensors, pressure sensors, ultrasonic proximity and ranging sensors, capacitive proximity sensors, optical proximity and ranging sensors, and a full line of level switches. EMS started with the design of ultrasonic sensors and offers a full line of ranging and proximity sensors using ultrasonic technology under the Sonarange and Sonaprox trademarks. EMS sensors can be fully integrated into and operate with standard PLC, DCS, SCADA, or other control system using standard operating voltages and output signals. Our sensors also can be used with our "Sentry" line of controls for a complete "stand alone" system that is rugged, reliable, and economical. EMS sensors are suited for applications in a wide variety of industries such as; food processing, packaging, factory automation, chemical processing, pulp and paper, water and wastewater, textiles, metals processing and finishing, robotics, and industrial process control. |
