Sitron CF series thermal flow switches

The Sitron CF series of thermal flow switches is suitable for flow and low flow detection of liquids or gases in pipes or ducts.

With no moving parts to wear out, the CF Series is claimed to be able to deliver a longer life and lower maintenance costs when compared with alternative mechanical switches.

The combined flow switch and transmitter is durable and performs reliably under general industrial applications and harsh process environments with average response times of between 1 to 10 s. A display chain of eight LEDs is included to help the setpoint adjustment.

All models are manufactured using 316 stainless steel and can be coated with Halar when necessary for particularly aggressive mediums.

Standard operating temperatures for the aeries are between -10 to +120°C (up to 200°C available on request); combined with a maximum working pressure of 300 bar (4350 psi). Control components stock 24 VDC and 250 VAC powered versions - both of which have 5 A 250 VAC relay outputs.

The series has low flow sensitivity and is relatively insensitive to dirt and to most particles.
