Catalog excerpts

Sitron's versatile and intelligent line of Thermal Dispersion Flow Switch are compact switches and transmitters,with no moving parts, that can monitor and control the flow of liquid and gas in pipes and ducts. They can also be used for single point level detection for liquids. Sitron's series of flow switches and transmitters are available in different models that provide for different power supply, output and connection requirements. All models are manufactured using 316 S.S. and can be coated when necessary for aggressive mediums. All of the CF12 and CF420 models can operate in temperatures up to 248 F (120 ں C) and have a maximum working pressure of 4350 PSI (300 bar). A display chain of 8 LED's is available for all models to indicate flow rate (CF420) and to help the set point adjustment (CF12 series). Sitron also offers the option of sanitary connections such as Tri- Clamp as well as the standard threaded and flanged connections. In addition, the orientation of the enclosure can be rotated so that the LED display can be best viewed, after the process connection has been tightened. Sitron's line of flow switch monitors are highly reliable industrial instruments that provide the durability and speed required for today's general as well as harsh process environments for flow and level. >

Sitron's line of thermal flow switch is based on the principle of thermal dispersion. A typical configuration uses two platinum Resistance Temperature Detectors (RTD's) set within the tip of the sensor. One RTD is heated a few degrees above the temperature of the medium and the other RTD is used as a reference, sensing the actual process temperature. The second RTD also monitors the temperature of the medium, as any changes in temperature must be compensated for in the first RTD. As the process medium flows over the tip of the sensor it disperses some of the heat from the first RTD. The...

The CF12DC is a thermal flow switch designed to monitor flow status of liquids and gas and can also be used to detect level. A chain of 8 LED's gives the user a visual indication to help the set point adjustment. In addition, there is also a di-chromatic LED, which shows the switch point status of the unit. The sensing element and connection of the CF12DC is made with 316 S.S., can be coated when necessary and the enclosure is glass filled nylon. The CF12DC can be made with a great variety of process connections such as threaded, flange, or sanitary.For PTFE coating we recommend that the...

The CF420's nominal measuring range is 0.04 to 2.0 m/s. The switch can be set to trip at any value in this range. To calculate the velocity for your application, use the following simple formula: V= Please note that the 4-20mA option is scaled over 0 to 2.0 m/sIf the flow rate is in gallons per minute, you can use the factor:gpm x 0.0000631 = m/s 1.27 X Q > Q = Flow rate in mӳ per second D = Pipe internal diameter in meters V = Fluid velocity in meters per second D > 2 RCF420 . The F420 is the ideal solution when there is not a lot of space to install even a compact unit or when there is a...
