For wide pump differential using an additional switch see wiring diagram figure 8. The float switch is designed to open or close a circuit switch as a changing liquid level within a vessel passes the level of the float the switch point.
Mobrey Magnetic Vertical Level Switches Delta Controls
Mobrey level switch wiring diagram. Around the pressure tube after wiring. High and low level alarm 23 ordering information level switch models fitted with options listed appendix b. Note diagram shows starter fitted with 250v coil for 3 phase 3 wire supply. Mobrey float level switches are rugged robust and trusted globally for their long term reliability in the harshest of environments and the most hazardous areas. Lets start with the most basic float switch. Mobrey magnetic float switches are ideal for high and low liquid level alarm and pump control duties.
Switch point adjustments may now be made if necessary. Level mobrey vertical controls installation operation maintenance instructions. A two wire single pole single throw float switchthe rising action of the float can either close ie turn on a normally open circuit or it can open turn off a normally closed circuitinstallation scenarios might include a normally open float switch turning on a pump to empty a tank control schematic 2 or a normally closed. For critical area applications or general purpose control you need to trust that your level switches wont let you down. It is 316 stainless steel construction has a contact rating of 15a250v and the maximum temperature is 130 deg c. Emerson global emerson.
22 level switch purpose mobrey magnetic level switches are ideal for high and low liquid level alarm overfill alarm and pump control duties. Level switches certified to iec 61508 of this. Sma1 m switch by mobrey measurement is a magnetic liquid level switch and is the most cost effective of the horizontal switches. Operating levels differentials each switch has a nominal water level differential of 25mm between circuits a a and b b. Ideal for industrial applications such as pump control and high or low alarm duty on tanks and pressure vessels. Mobrey float and displacer level switches are rugged robust and trusted globally for their long term reliability in the harshest of environments and the most hazardous areas.

M switch is a float operated liquid level switch to give a voltage free contact for alarm. To obtain a differential greater than 25mm two switch units must be used and a holding circuit arranged for the starter control circuit see.
