The ZDT Analyzer/Alarm unit is a versatile microprocressorbased
oxygen analyzer designed primarily to meet the
requirements of the medium sized boiler and furnace market,
utilizing high quality zirconia oxygen probes, for energy
management.
The low temperature version of the ZDT is designed to operate
with the Model ZFG2 low temperature oxygen probe. The
probe sensor is controlled at 700°C.
The high temperature version of the ZDT is designed to
operate with the Model ZGP2 oxygen probe. The probe sensor
is temperature compensated from 600° to 1400°C. In the
event of probe thermocouple failure the temperature of the
process can be preset in the ZDT.
The standard analyzer has high/low alarm relays and a single
linear or logarithmic isolated retransmission. Display features
include %O2, cell temperature, heater control output, cell mV,
alarm set points, calibration sequence diagnostics and output
settings.
The analyzer provides oxygen readout with computation
based on the probe mV signal. The mV output signal is
Nernstian in form and follows the equation:
P0 E(mV) = 0.0496 T (log10 ––– ) ±C (mV)
