Tilt Switches and Control Units
 |
For Sensing and Controlling Levels with a Wide Variety of Solids and Liquids
The Ramsey tilt switch is actuated when material rises to tilt the probe 15 degrees or more from its vertical position. The mercury switch is precisely positioned so that, regardless of direction of tilt, the normally closed contacts are caused to open. The switches are encapsulated in various sizes to suit the application.
* Also available in mercury free design

Belt Misalignment Switch
 |
For protection of Belt Conveyor and Personnel.
Belt misalignment switches are mounted on the top or bottom of the conveyor stringer with the actuating arm adjusted to the outside edge of belt.
If the belt skews or runs-off contacting actuating arm, displacing it from the arm's normal vertical position, one or more of the microswitches are contacted |
|
Safety Cable Pull Switch
 |
A pull cable is terminated at one end from a fixed mounting and attached at the switch end to one of the actuating armholes. Force applied to the pull cable at any position causes the actuating arm to rotate 20deg. to a tripped-locked position. This will stay locked until manually reset by the reset lever. |

C-Level Strain Gauge Level System
 |
The C-Level is a non-contact, constant bin level system. It can be used with liquids, solids, corrosive or volatile materials. Sensors are mounted in the support structure of the bin and register the deflection as the weight increases and decreases. This is a 2% device. |

SonaTech and SonaMaster Sonic Level Measuring Systems
 |
Ramsey's Sona Tech and SonaMaster systems transmit sound waves toward the stored material and receive the reflected echoes. Material level is determined by calculating the elapsed time between sending the sound signal and receiving its echo. Sona Tech and SonaMaster systems are state-of-the-art. They provide more penetrating power because they operate in the 5-30 kHz range. That means superior performance in dusty, turbulent or steamy atmospheres. |

The BOB II Inventory Measurement System
|
The "BOB" not only measures up but it also measures down. The remote sensor quickly lowers a weighted bob (2ft/sec) to the surface of the product. As the bob descends, a micro-controller counts pulses from an encoder and determines the amount of cable released. Slack in the cable is detected when the bob reaches the product, causing the motor to reverse and retract the bob. The retract distance is also measured and compared for diagnostic purposes to assure that the measurement was accurate. |
|
CAP Series Capacitance Level Control
|
The "CAP" Series Capacitance level control is designed for point level monitoring of solids, fluids or slurries in bins, vessels and chutes. The CAP control detects the presence or absence of material by sensing a change in capacitance caused by the difference in dielectric constant of the vessel material and air. |
|
RT Rotary Level Control
|
The RT Series rotary level control is designed for point level monitoring of solids in bin, vessels and chutes. The RT eliminates the most common causes of rotary control failure. The de-energizing motor shuts off when material is present, rather then entering a stalled condition. This reduces wear and operating temperature and extends motor life. |
