Trash Compactors – PS61 Series Pressure Switch from Gems Sensors & Controls

Trash compactors are one way that we can improve the environment by reducing the volume of trash that goes into a landfill.  Smaller bags, smaller loads means that dumpsters can hold more trash and smaller loads entering the landfill. This also yields fewer times the dumpster needs to be emptied which equals less use of fuel to dump the load.

A pressure switch is needed to monitor the amount of hydraulic pressure in the compactor’s system. As the compactor compresses the material, pressure is placed on the system. A pressure switch monitors the system pressure and turns off the hydraulic pump when pressure is not needed and turns it on when there is a demand for more pressure.

But, compacting large amounts of trash is quite a challenging task. The materials that need to be compacted vary from strong to weak. The hydraulics in the compactor sometimes push very hard to crush the contents and other times push more gently. When a piece of trash is being compacted and gives way, spikes can occur in the hydraulic system. 

Application Challenge:

Finding a rugged pressure switch that can provide an accurate signal when used heavily in an aggressive environment and withstand potential spikes. The pressure switch can see some high spikes during use. This causes immediate and high pressure in the system and can damage weak pressure switches. Some compactors are also cleaned via a power washer. 

The pressure switch required will need to be able to handle the strong water pressure and water spray to survive. Shock, vibration, and heat are also present very frequently.

Application Solution:

The redesigned PS61 Series Pressure Switch has been extensively tested to withstand up to 7,000 psi (483 bar) of pressure without incurring any type of damage. This is critical in trash compacting applications.  Also, MIL-STD 202G testing for vibration and shock has been achieved. The electrical connection back-ends have been designed and tested to IPX7, IPX9K, and IP6KX so that they are resistant to dust, high-pressure/high-temperature wash-down, as well as submergence.

The PS61 Series Pressure Switches have been designed and tested to survive for over 2,000,000 cycles so that the owner can be assured that their equipment will have a long life.
