Flow - Sitron - #5

SSitron

The CF420 model is a flow transmitter that measures the velocity of the flow. It is ideal for use in measurement and control applications. The CF420 provides two output options; a 4-20mA analog output and a PNP/NPN output. For the 4-20mA output, the electronics' module converts the signal from the probe to a 4-20mA analog output, which can be used to indicate flow rate. For the PNP/NPN output, the measured flow rate is compared to the set point value selected by the user and the switch changes state once the set point value has been achieved.

The CF420's microprocessor based electronics and unique self-calibration program gives the flow transmitter superior temperature compensation, a fast response time and increased long term switch point stability. Even in the event of a power failure, the calibration program will store values for maximum and minimum flows for up to 10 years.

A chain of 8 LED's gives the user a visual indication of the flow rate as well as set point status, and one di-chromatic LED indicates switch point status. In addition, if there is a problem with the unit, the 8 LED's will flash continuously providing troubleshooting information.

The conical shape of the sensor's tip means that the probe can be installed at almost any angle in the pipe and that if the probe is miss-aligned, accuracy will not be affected. The sensing element and connection of the CF420 are made with 316 S.S. and the enclosure is glass filled nylon.

For aggressive mediums the CF420 can be made with Hastelloy-C. We do not coat any of the CF420 models. The CF420 can be made with a great variety of process connections such as threaded, flange, or sanitary.
