Houston, TX (May 2, 2005) - ASI Instruments, a leading manufacturer of state-of -the-art instrumentation for level detection and measurement of dry bulk solids, today announced the ShieldPoint™ series of RF (Radio Frequency) capacitance switches. Built for point level detection in a wide variety of challenging applications, from sticky slurries to low dielectric bulk solids, ShieldPoint's rugged probe designs mean there are no moving parts to wear out. The series features LED operation and calibration lights, visible through its standard window cover, with an "Out-of Calibration" indication. The ShieldPoint's modular electronics are built around ASI's patented ASHIELD™ technology which provides immunity to material build-up, thus ensuring reliable and repeatable operation.
The ShieldPoint 300 is a single-point level switch featuring 3-element shielded probes and a 10 amp DPDT relay. The ShieldPoint 400 is a multi-point switch with a variety of probe options, including a 3-element probe, Teflon coated or bare rods and cables, along with 2 SPDT 10 amp relays. The ShieldPoint 400 allows a choice of three operating modes - single setpoint, dual setpoint, and pump control. The dual setpoint function means the unit can be used to replace two single point switches for the cost of one.
"RF capacitance switching is a time tested technology," said Robert Hotard, Product Manager for Radar and RF products at ASI Instruments. "The ShieldPoint series adds to that with an easy-to-use calibration process and the industry's largest selection of rugged probe designs. You could say we took what was already a good wheel design and put a better set of tires on it."
Rugged & Easy to Calibrate
ShieldPoint features a simple, one-step calibration process that uses an external magnet. With the LED indicator lamps, visible through the glass window cover, adjustments such as calibration, sensitivity, and time delay can be made while maintaining the explosion-proof integrity of the switch. The "Out-of-Calibration" warning lets the user know when build-up is present on the probe and recalibration may be needed.
The ShieldPoint300 and ShieldPoint400 are housed in single compartment, powder-coated aluminum enclosures. Stainless steel enclosures are also available for corrosive applications where aluminum may not stand up to the elements. For hard to access installations, a remote mounting option with a range up to 200 feet provides user friendly flexibility. For increased protection, dual-compartment housings allow users to isolate wiring and terminations from internal electronics.
Wide Variety of Probes
The ShieldPoint family includes a wide variety of versatile probe elements, including a number of specialized options:
*Standard probes for multi-purpose applications
*Stub or Bent probes for small hoppers and vessels
*Flexible or Rigid Tip Extensions for increased range
*Cable probes for ranges up to 150 feet (45 meters)
Custom Pipe Extensions are available for deep tanks or vessels for low-level switching, up to 20 feet (6.1 meters).
Unique rolled seals lock all elements of the probe in position and ensure no part of the probe can fall into the process or be blown from the mounting.
Pricing & Delivery
ASI Instruments' ShieldPoint RF capacitance switches are available for immediate shipment. Prices for the ShieldPoint300 start at $570 and ShieldPoint400 start at $670. Delivery is one week from receipt of order for standard units.
