The fb-18(3-phase) pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. It features different diaphragms for compatibility with a wide variety of fluids, and various terminations including a metri-pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable construction, compact size, and enhanced set point integrity. It can be widely used for pool and spa, anti-skid braking systems, water pump systems, and dental air compressors etc. 0.3kg, cartons
Fb30 pressure switches are used to regulate tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. Equipped with an unloader valve, they could prevent compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. Both one and four-ports manifold style are available which provides easy mounting of valves and gauges.. 1) operating pressure range: 5bar-12 bar; 2) differential pressure range: 2bar 3) 20a, 240vac, 50hz 0.3kg, cartons
Pressure switch Specifications For use with fluorinated refrigerants as well as with a air and water.(allowable fluid temp.:-10f¦~+110f¦) Various contact functions available. With spdt contact mechanism. Renovated micro-switch structure ensures the reliable switch function. Manual-controlled and no use of other instruments to have a function test. Flexible mounting plate suits various kinds of application.
Compact size and unibody type Excellent EMI/EMC and noise properties Embedded ASIC for high accuracy Wide range(-40 to 100°C) DIN and cable type Perfect compatibility with dotech's air compressor controllers
LF10-L pressure switch is a pressure-operated electric switch for use in regulating the tank pressure between two preset values on electrically driven air compressors. It is available with an unloader valve, which prevents compressors from starting under load, and an on-off button for manual cut off the compressor. A four-port manifold style is available which provides a means for easy mounting of valves and gauges.
