Watertown, Ma - United Electric Controls (UE) introduces the innovative
solid state One Series 2-Wire Pressure Switch that detects
blockage of the sensor port due to process debris, slurries or
crustation build-up. Operating on just two wires and powered
from PLC/DCS discrete input, the One Series diagnostic
capabilities include detection, signal and display of the
plugged or isolated sensor condition, signaling operators to
take corrective action to restore normal process flow and
assure accurate monitoring and control. With Plugged Port
Detection users can reduce process down-time, lower
maintenance costs, and help assure accurate process and safety
measurements.
The One Series 2-Wire Switch is an economical alternative
to transmitters, providing significant cost-savings with a
list price of only $375.00, and simplified wiring and
installation. The One Series provides solid state reliability,
patented IAW® diagnostics, local display and set-up, and
carries cULus and CENELEC agency certification for Division 2
and Intrinsically Safe hazardous locations. With break-through
2-Wire technology, it can be used as a drop-in replacement for
a mechanical switch in existing applications without
additional wiring or modification. In addition, the One
Series' Plugged Port Detection eliminates faulty "live zero"
signals that may result when transmitter sensor ports are
blocked.
Housed in a rugged Type 4X/IP56 enclosure, the One Series
is equipped with welded #316 stainless steel sensors that
cover ranges from 0 to 4500 psi. The front panel of the One
Series provides digital display of process pressures and
tamper-proof keypad adjustment for selecting switch set point
and operating mode. Operators can activate or disable the
Plugged Port feature based on process parameters and
conditions. In the field, they can select an on-off dead band
from 0 to 100% of the pressure range, assuring precise tuning
to maximize system efficiency, especially for applications
such as level control or pump operation.
Available for immediate delivery, the new One Series 2-Wire
line joins the UE family of innovative and cost-effective
detection, sensing and switching pressure and temperature
products. UE products and service are available through our
network of worldwide stocking distributors. To receive
