Cherry’s switches transmit the valve position through a signal line wired through the switch to the equipment or computer being signalled. They eliminate potential driven device damage due to over-torque conditions in either direction of operation. Another advantage offered by Cherry’s miniature switches is their high amp rating (from 0.05A to 25A) which enables the switch to control a relay or other plant devices, such as pumps or motors, in addition to transmitting valve position.
Valve applications often require the inclusion of sensors and here again, Cherry’s range of reed and solid state sensors offers the advantage of being sealed for protection and extended life in corrosive environments. In hazardous or remote locations, Cherry’s new DS hall sensor can be mounted in the same locations as a miniature switch and works in environments that must be contact-less. Actuated by a magnetic field, it meets the non-incendiary requirements for Division 2 hazardous locations.
