CT6103, $2312, shown smaller than actual size.
The CT6100 Series microprocessorbased circular chart recorders are
available in 1-, 2-, or 3-channel
variants. They combine the simplicity
and clarity of pen drawing with the
versatility of microprocessor control.
Each channel is compatible with all
industry-standard sensors and signals,
including thermocouple Types J, K,
T, E, N, R, S, and B; Pt100 platinum
RTDs; and 4 or 20 mA current loops.
Low and high measurement ranges
are provided for each input type;
separate range cards are not required.
Multi-input versions feature
optoelectronic isolation of the input
stages to eliminate troublesome
installation ground loops. Multislope
integrating 16-bit A/D converters
ensure precise measurement by
sampling the input every 0.5 seconds.
Thermocouple and RTD
characteristics are fully linearized.
The recorders use automatic
cold-junction compensation for
thermocouple measurement.
All CT6100 Series models feature
alarm relays. Single-pen recorders
are equipped with 3 fail-safe singlepole changeover relays; 6 relays are
standard on the 2- and 3-pen versions.
Color-coded LEDs indicate the status
of each relay. All relay functions are
user selectable; setpoint values and
hysteresis levels are entered
directly via the keypad, while relay
action and channel assignment are
selected from user-friendly menus.
Circuit precision is matched by the
backlash-free pen-drive mechanism,
which has a positioning resolution
greater than 0.1%. An integral
S-45
feedback potentiometer enables
closed-loop monitoring
of each pen position.
Each recorder uses a low-maintenance
stepper motor. The rotation speed
of the 244 mm diameter chart is
microprocessor controlled and user
programmable.
All CT6100 recorders are housed in
a strong molded case that can be
panel or surface mounted. A
gasket-lockable door protects
internal components from harsh
industrial environments and offers
protection rated to NEMA 12 (IP55).
A tough acrylic window lets the user
view the chart trace, digital channel
readings, and alarm status with the
recorder's door closed.
