Pneumatic Tuffy® - 1

TUFFY® T3Side Mounting Level Controls Tuffy liquid level switches are float actuated devices designed for horizontal mounting in a tank or vessel through threaded or flanged pipe connections. The compact size allows for installation in small vessels, while its many features provide a variety of application uses. The single switch mechanism is available in SPDT or DPDT forms on units designed for adjustable, narrow or wide differential and interface service. FEATURES * Maximum Process temperature: +400 °C (750 °F). Minimum Process temperature: -55 °C (-65 °F). * Maximum process Pressure: 150 bar abs (2160 psi). * Specific gravities as low as 0.4. * Wetted parts in 316/316L (1.4401/1.4404) or Hastelloy C (2.4819). * Available as: - Flanged - Threaded - Flanged or sealed cage mounted. ® Consult factory for proper partnumbers MODELS * Narrow differential switch (for alarm functions) - standard pressure (up to 50 bar abs (720 psi) - high pressure (up to 150 bar (2160 psi). * Wide adjustable differential switch (for control functions) * Interface switch (detection of interface level between liquids). * External cages. * Compact versions: - pneumatic narrow differential switch - electric narrow differential switch. APPLICATIONS * Sour service (NACE). * High/low alarm. * Single pump control. * Day storage tanks. * Corrosive processes. * Process vessels. * Boiler low water cut off. * Interface level. * Dirty process high level w/offset. * Installations in hazardous area.

SWITCH MECHANISMS All TUFFY® are available with a selection of switch modules that vary in switch rating (Amp) and max process temperature allowance. The max temperature is dependent upon the housing material selected. Consult table below, before selecting the proper module in the order number structure on pages 3, 5, 7 or 9.

Pneumatic Tuffy® - 3

The Tuffy achieves switching action through the use of a magnetic switch mechanism and a magnet attached to the float assembly. Separating the two magnets is a non-magnetic pressure barrier. As the liquid level changes, the float, and therefore the float magnet, moves. The float and switch magnets repel each other causing movement of the switch mechanism, tripping the switch and making or breaking an electrical circuit.
