DWYER Instruments has announced the release of the Series SF2 sight flow switches.
These switches are suitable for protecting electronic equipment from coolant flow failure on medical equipment, semiconductor processing equipment, x-ray and other high power tubes, and robotic welding equipment.
The brass unibody construction, one-piece composite rotor, and ceramic shaft deliver durability with broader chemical, temperature, and pressure capabilities.
The Series SF2 features a temperature limit of -29ºC to 100ºC.
The model SF2-1 has an SPDT relay output. Set points are fully adjustable over the specified flow range.
The model SF2-2 features a pulse output proportional to the rate of flow.
The 4.5V to 24V dc pulse output is compatible with most digital logic families.
