-NOTE-

Electrical specifications are valid over a -25° to +50°C range unless otherwise specified. Non-condensing environment required.

Number of Vibrating-Wire Sensors Measured

Up to 2 vibrating-wire sensors can be connected to the analyzer module. Additional sensors can be measured by using an AM16/32-series multiplexer.

Power Requirements

9.6 to 16 Vdc

Analog Input/Outputs

2 differential (DF) vibrating-wire measurements (V+ and V-) and 2 single-ended (SE) ratiometric resistive half-bridge measurements (T+ and T-) for vibrating-wire sensor's onboard temperature sensor.

Digital Control Ports

3 digital control ports (C1 – C3)

• C1 functions as an SDI-12 I/O communication port.

• C2 functions as a Clk output for multiplexer control.

• C3 functions as a Reset output for multiplexer control.

RS-232 Port

1 9-pin RS-232 port (for connecting to a data logger COM port)

Measurement Resolution

0.001 Hz RMS (±250 mV differential input range; -55° to +85°C)

Measurement Accuracy

±0.013% of reading (±250 mV differential input range; -55° to +85°C)

Input Voltage Range

±250 mV (differential) for vibrating-wire inputs

Common Mode Range

±25 V

Baud Rates

Selectable from 1200 to 38.4 kbps. (ASCII protocol is one start bit, one stop bit, eight data bits, and no parity.)

Memory

• Either 128 or 512 kB of SRAM

• 2 MB of OS Flash
