MECHANICAL

VIBRATION SWITCH

■■ Linear trip adjustment throughout entire range of sensitivity adjustment knob

■■ More equal sensitivity on all three axes compared to traditional mechanical vibration switches

■■ Dual SPDT Form C relays to trigger to two simultaneous actions

■■ 24 VDC, 120 VAC and 240 VAC remote reset models available

PATENTED LINEAR ADJUST DESIGN

PROVIDES MORE LINEAR CONTROL

OF TRIP SENSITIVITY

The Linear Adjustable Mechanical Vibration Switch (Models

[EX]685AX9) is uniquely designed to provide improved sensitivity adjustment compared to current designs within the industry. The end result allows the user superior control of the trip level set within the switch and improving the protection of their rotating asset (reference sensitivity testing below).

Additionally, due to its innovative design and manufacturing process, the Linear Adjust Mechanical Vibration Switch is more cost competitive than any other existing mechanical vibration switches in the industry, including OEM volume pricing.

APPLICATIONS

■■ Cooling Towers

■■ Evaporative Condensers

■■ Steam Condensers

■■ Air-Cooled Heat Exchangers (Fin-Fans®)

■■ Large Blowers and Fans
