NVM Pneumatic Level Switch
* Air (Lubricated) - Any non-flammable, non-toxic, non-corrosive gases except oxygen.* Liquid - Oil or non-corrosive liquids within specified pressures SMC Mechanical Valves have been designed to meet general industrial standardsand are capable of long, trouble-free life under stringent operating conditions. Thesimple construction, utilizing corrosion resistant aluminum Die Cast bodies withoptional heavy duty actuators and Buna N seal design, ensure positive operationand media control
LSX switches are for use either indoors or outdoors in hazardous atmospheres as they area completely sealed explosion-proof device.Mounting hole location and tracking is sameas the long established MICRO SWITCHML-E1 explosion-proof switch.An optional mounting plate provides thesame tracking and mounting as the standardHDLS. The majority of HDLS operatingheads and circuitry options are available onthe LSX.
The PS-35 is a point level (on-off) pneumatic switch device used in conjunction with A Magnetic Liquid Level indicator.The unique magnetic coupling action eliminates the need for such things as seals, diaphragms, springs, or torque tubes. Sinceprocess connections to the switch are eliminated, the user is insured complete isolation from the process. Valves are notrequired to block off the switch from the process for maintenance or operational testing. Preventive maintenance functionsare greatly reduced since the switch never contacts the process fluid.
AT 200 External Transmitter
The At200 is based upon the magnetostrictiveprinciple. The sensing tube contains a wirewhich is pulsed at fixed time intervals. Theinteraction of the current pulse with the magneticfield created by the magnet causes atorsional stress wave to be induced in the wire.This torsion propagates along the wire at aknown velocity, from the position of the magneticfield and toward both ends of the wire. Apatented piezo-magnetic sensing element placedin the transmitter assembly converts the receivedmechanical torsion into an electrical return pulse.The microprocessor- based electronics measuresthe elapsed time between the start and returnpulses and converts it into a 4-20 mA DC outputwhich is proportional to the level being measured.
TGS 20EX Proximity Switch
The TGS 20EX Switch is a Magnetically Activated SPDT Bi-Stable Latching Hermetically sealed reedswitch. The TGS 20EX is actuated by a passing external magnetic field and remains latched after themagnetic field continues to rise or fall. Reversing the magnetic polarity causes the reed switch totransfer and latch back to its original state.
