JAMESBURY QUARTZ LIMIT SWITCH FOR HAZARDOUS AREAS AND GENERAL PURPOSES

Transcription

1 JAMESBURY QUARTZ LIMIT SWITCH FOR HAZARDOUS AREAS AND GENERAL PURPOSES The new improved Quartz is available in explosion/flame proof (QX), intrinsically safe and nonincendive (QN) and general purpose (QG) versions.the robust urethane coated anodized aluminum construction makes this platform extremely durable and well suited for use in corrosive, heavy wash down environments. A broad range of switching, sensor and position transmitter options may be selected to accommodate most applications. Options include 2, 4 or 6 mechanical or proximity switches, position transmitters with or without switches and the Dual Module with double SST or double Namur sensors. Features and Benefits Enclosures Optimized for Environment QX: Explosion-proof, QX: Explosion-proof, water tight and water corrosion-proof tight and enclosure has ATEX corrosion-proof II 2 G, EEx enclosure d IIC T5/T6 is approved certificate and can be used for in use Zone in div.1/zone 1 areas.

NEMA All 4, 4x, enclosures are rated and IP67 6. (NEMA 4, 4x, and 6). Rapid Enclosure Access Screw-on cover allows quick enclosure access, saving valuable maintenance and set-up time. The cover provides a vapor tight seal and allows easy entry to internal components. Quick Set Cams are Easy to Adjust Touch and Tune switch settings allow you to make adjustments in seconds without the use of tools. Wide Variety of Monitoring and Control Switching options include Dual Module sensors, Maxx-Guard proximity switches and mechanical switches. Continuous signal output is available in a 4-20 ma position transmitter. Faster Wiring Pre-wired and labeled terminal strip enables quick, convenient attachment of field wires. Dual Shaft O-ring Seals Eliminate Corrosion Top inner and bottom outer shaft o-rings seal the drive bushing from both external corrosives and internal contaminants that enter the enclosure. Special Drive Bushing Assures Long Cycle Life The oil impregnated bronze bushing maintains smooth operation and eliminates the potential for shaft seizure due to actuator shaft eccentricity. Space Saving Visual Indication Visual indicator offers excellent viewability without sacrificing accessibility or adding to space requirements. Indicators are also available with continuous percentage or three-way indication. S /2012

2 METSO S140-1 Speed Installation With LED Indication Consolidate Your Components and Minimize Costs The Quartz design offers up to three conduit entries with extra wire terminations. By terminating solenoid valves in the switch enclosure significant savings are realized by eliminating a junction box, wiring, conduit materials and labor. Save Space with Low Profile Design Coordinated visual indicator and LEDs give you an extra measure of safety and increased convenience during plant start-up and operation. Green visual indication and green LED means the valve is open and the control circuit is properly operating. Red visual indication and red LED means the valve is closed and the control is properly matched. Quartz Expeditor (8H), (8Y) Fill Control Applications Fill tanks and hoppers rapidly and accurately. The Quartz Expeditor s field adjustable intermediate position reduces flow as the full level approaches. You get fast, economical topping off every batch. Flow Dampening Applications The Quartz Expeditor allows fast closure yet gentle, gradual shut-off from a preset intermediate position. You get prolong piping life, improved process flow performance and less potential for catastrophic failure. Clearance above the actuator is critical in complex piping systems. The Quartz displays valve position and encloses all electrical components in a compact explosion-proof/flameproof compartment. Applications and Adaptation Quartz Mounting Systems Low profile convenient mounting systems are readily available in stainless steel for most non- Namur and Namur (VDI/VDE 3845) actuators. You get direct output on rotary actuators, and easy access to positioner internal adjustments. Manual Valves Proper fit and operation are assured with custom designs for each manual valve. Hundreds of unique mounting systems have been designed and fabricated for manually operated valves. The Expeditor enables three position control of On/Off valves in combination with two standard solenoid valves. 2 TECHNICAL BULLETIN 6/12
