Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 Float Switches—Class 9036, 9037, and 9038 Introduction Square D™ brand offers a wide range of electromechanical level control products. • • • 9036DG2 Class 9036, Open Tank Class 9037, Closed Tank Class 9038, Mechanical Alternators Class 9036 Open Tank Type D and G The Class 9036 Type D and G float switches are lever operated and designed for open tank applications.
Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 Class 9037 Closed Tank Type E The Class 9037 Type E switches are flange mounted. Float movement is transmitted through a quad ring seal. Each switch consists of a basic switch, float rod, and float. The switch can be configured in the field for contacts that open on liquid rise or close on liquid rise. These switches are used for top mounted or side mounted, closed tank applications.
Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 Selecting a Float Switch 9036DG2 Standard float switches have two contacts that close when the liquid rises above the designated level. This contact configuration is used for tank emptying applications. Float switches are also available with reverse (Form R) and double throw (Form H) contacts.
Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 The center-hole float is used in applications requiring long lengths of tubing and large liquid level changes. A compensating spring, used for longer lengths of tubing, supports the weight of the tubing and stops. When a compensating spring is used, the float must be buoyant enough to lift up the switch lever and heavy enough to trip the switch lever down. The rod has four stops.
Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 Class 9036 Type D and G Open Tank Float Switches Table 11 lists Class 9036 float switches and modifications. Table 11: • When ordering a factory installed modification, add the Form number to the end of the float switch catalog number. For example, to select a 9036DG2 switch with reverse action, order 9036DG2R. • Field installed modifications, when available, are ordered as kits.
Commercial Pressure and Float Switches for Power Circuits Float Switches—Class 9036, 9037, and 9038 Table 12 lists the trip forces and compensating spring requirements for Class 9036 Type D and G float switches. The trip force can be adjusted on the Type G switches by changing the lever length position.
