Sensors transduce phenomena into measurable electrical forms by modulating
voltage, current, resistance, status, or pulse output signals. Suitable sensors do
this accurately and precisely
(p. 522). Smart sensors have internal measurement
and processing components and simply output a digital value in binary,
hexadecimal, or ASCII character form. The CR800, sometimes with the
assistance of various peripheral devices, can measure or read nearly all electronic
sensor output types.
Sensor types supported include:
• Analog
o Voltage
o Current
o Thermocouples
o Resistive bridges
• Pulse
o High frequency
o Switch closure
o Low-level ac
• Period average
• Vibrating wire
• Smart sensors
o SDI-12
o RS-232
