The NGS series is hands down one of the toughest level switches on the market. The float and all other wetted parts are made of 316 stainless steel. The switch mechanism is activated by a permanent magnet external to the switch housing so that no penetrations exist between the process and the switch internals. This mode of operation results in a very reliable switch which requires no external power to operate. The high capacity 10 amp switch will handle most electrical loads such as relays...

is sensitive to changes in capacitance. When a person's body or a grounded metal object comes into contact with the antenna, a large change in capacitance results. Because it is capacitance, rather than electrical conductivity which is sensed, it isn't necessary to make what is commonly thought of as an electrical connection with the antenna; therefore, the antenna may be covered with paint, electrical tape, or other thin insulating material and still function normally. When sufficient external... (read more)Browse Touch Switches and Tactile Switches Datasheets for Gordon Engineering Corp.

the SC700 does not require an external reference. The sensor operates in a manner that is similar to a simple capacitor. A high frequency oscillator is located within the tip of the probe. When the tip of the probe comes in contact with the medium, the frequency of the oscillation reaches a preset point and the detection circuit signals the switch to change state. The SC700 is a compact point level switch that can be made with many types of process connections,such as; threaded, flange or sanitary... (read more)Browse Level Switches Datasheets for Sitron

not to static or system pressures. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch thus producing the required signal. This signal can be used to actuate audible or visual alarms as well as relays, or other control. Piston travel is short which insures low hysteresis. Pressure drop across flow switch varies from 0.035 to 2 psi (at maximum flow rates for air and for liquid). Universal mounted units are outfitted with a spring...
