MCDONNELL & MILLER 112770 120610 - SPDT 1" NPT. GENERAL PURPOSE NEMA-4 FLOW SWITCH,.

SPDT 1" NPT. GENERAL PURPOSE NEMA-4

The SPDT 1 Inch NPT. General Purpose NEMA-4 Flow Switches that we offer are most commonly used for on/off control of single phase liquids in conjunction with a controller. It is the industry standard for HVACR applications, and is suitable for use over a variety of industrial fluid processes. These products connect directly to standard pneumatic controllers, actuators, timers or other devices equipped with a 1 Inch NPT conduit connection at the output side to power the

Our general purpose NEMA-4 SPDT Flow Switch is designed for use with a wide range of liquids and gases. With a maximum operating pressure of 1500psi, these switches are ideal for commercial wastewater systems, breweries, wineries and food processing plants. Our SPST or DPST Flow Switches feature six standard models and our solid state electronics allow for plug-in simple installation.

The highly accurate General Purpose Nema 4 SPDT Switches provides overload protection and status indication. The SPDT switch can be panel mounted or DIN-rail mounted, and the handles are made of molded PVC.Offering optional pulling force ratings in both spring return and normally-open configurations.

This SPDT - SPeed/DIrection/TIMing switch is a common semiconductor flow switch, used to monitor flow of gaseous, liquid or steam for control applications. The 1/2" NPT model is designed for general purpose use with nonsparking solenoid valves used in customer processed air, nitrogen and gas lines. These switches have an adjustable setpoint switch range from 10 to 20 PSI (0.7 - 1 bar).

The 112770/120610 SPDT Series pressure switches are designed to switch the main power of pump or other equipment on and off, when the pressure drops below or rises above a set level. These general-purpose, manually reset switches are ruggedly constructed of material resistant to wear from steam and chemicals. The unique construction of these switches assures long life.

The 112770/120610 switch is a one pole, three position, a SPDT actuated device. When the operator is in the ON position, the firing signal is routed to "ON". When in the OFF position, the firing signal is routed to "OFF" and when in the AUTO position; the firing signal returns to "ON" when flow exceeds 80% of differential pressure set point.

The Series 1206 patented German silver particle infused diaphragm design of the Solid State Pressure Switch is ideal for high pressure, high flow rate, corrosive or dirty gaseous sensing. The 1206 replaces the 1200 in most applications where a diaphragm is not required.
