Q-Series Noise Free LED Bargraphs

Q-SERIES NOISE FREE LED BARGRAPHS Noise free technology, designed for the most sensitive of applications.

Description

Performance features

• Combined 4-digit numerical display and bargraph in one panel instrument.
• Replaces many standard switchboard instruments.
• Optional noise-free circuitry does not interfere with other equipment; meets military requirements.
• Optional input circuits for most process control inputs: current, voltage, thermocouple and RTD.
• Many instrument power options available: 120/240VAC; 24VDC and other DC levels.
• MIL-spec versions of these instruments meet most applicable EMI, Drip-proof, salt spray, shock and vibration requirements

* Military units use Mil. Spec components and are priced accordingly.
** Nuclear units have been seismically approved and, generally speaking, can come in either conventional or noise-free circuitry.
† The most cost effective Q-2 units will use conventional circuit design and components. Since "noise-free" units use a proprietary display and circuitry even in commercial (non-military) applications, they will be more costly than conventional designs.
‡ Available but minor redesign may be required.
