Starting Feb 1st 2018, the Q2000/Q9000 series will be discontinued. As a possible substitute, please check out the PTDP Meter or Pt Controller for details.

The QUANTA 9000S is a 4-digit meter/controller for use with pressure transducers and load cells which require bridge excitation and preamplification of microvolt signals. Deadload and tare adjustments make it ideal for weighing applications. Like process meters, it provides zero and span adjustments for direct readout in engineering units. It can also be used as a microvoltmeter with differential input.

EXCITATION SUPPLY AND PREAMPLIFIER
The Q9000S provides a constant-voltage excitation supply, which is adjustable from 1 to 10 V and can drive up to 30 mA. It also provides a high-impedance preamplifier, which is continuously adjustable so that signal levels from ±2.0 to ±500 mV can produce the full-scale display of ±9,999 counts. At 10 V excitation and maximum gain, full-scale readout can be obtained with strain-gauge sensitivity as low as 0.20 mV/V. An active filter is provided for noise reduction.

BRIDGE CONNECTION
Bridges can be connected by 4 or 6 wires. In 6-wire connection, two lines sense the voltage applied to the bridge and compensate for lead resistance (these two sense lines require the optional PCB connector D1).

RESOLUTION AND ACCURACY
Resolution is one part in ±9,999 counts, or 0.01% of full scale. Accuracy is 99.9% of reading. The measurement is ratiometric to reduce errors due to temperature and power- line variations. The same internal reference controls the meter gain and the excitation level.

POWER OPTIONS
Six types of meter power are available: 120 Vac, 240 Vac, 24 Vac, 5 Vdc, isolated 9-32 Vdc, or isolated 26-56 Vdc.

ANALOG OUTPUT OPTIONS
A 0.2 mV/count (±2 V full-scale) analog output is standard and is useful for driving a strip-chart recorder. An additional analog output can be provided by an optional vertical plug-in board. Available output signals are 0-5 Vdc, 0-10 Vdc, 0-1 mA (source or sink), and 4-20 mA (source or sink). The top and bottom of each output range can be scaled to fit a user-selected display span.

Additional outputs can be provided by a horizontal upper board. Available options include single-setpoint control with one 10 A relay, dual-setpoint control with two 10 A relays, 4-20 mA proportional control (source or sink), time-proportional 2 A solid-state relay control, and isolated, parallel BCD output. For additional information, please refer to the QUANTA, Options, and Mechanical sections.
