Multi-channel data logging devices through multi-channel switch for 2 to 16 input signal switching, each circuit measurement, display, alarm processing, etc. The instrument supports a variety of input signals simultaneously, such as: temperature sensors (thermocouple, RTD, etc. ), humidity, pressure, level and flow transmitters, multi-physical measurements on a single instrument, display and control; can be composed of data records and micro-printer, curve recording system; also with remote data acquisition software components surveillance system.
Since the multi-channel data logging devices one by one as processing multiple input signals, input signal, the more the longer tours a week, and thus suitable for the signal points, but the change is not fast or speed of response less demanding situations, such as communications temperature room, offices, workshops, warehouses, hospitals, archives, cold storage, test equipment, HVAC, agriculture and breeding environment, and humidity measurements, or industrial site, medical, food, water and electricity, water and other sectors of temperature, pressure, liquid level measurement.
l input type for each channel selectable (universal input)
l parameters of each channel can be independently set or a unified set
l Each channel can be set to one or more alarm points, and each point has a separate alarm indicator
l each alarm point can be shared or used alone alarm output relay, and each relay has a separate indicator
l alarm output relay can be extended to 32
l measured values can be set to tour the multi-display or a road fixed display
l thermocouple input selectable 0.1 ℃ or 1 ℃ Display Resolution
l channel switching time and tour the effective number of channels can be set
l transmitter output selectable input of all maximum, minimum, average, or specify the channel, touring and other multi-output mode
l Print output supports text printing and curves print
l text printing including print time, the measured values for each channel, all channels in the maximum, minimum and average
l support amendments and the cold side of each channel measurement value correction
