TA-500 Temperature Averager

The TA-500 is a single channel precision temperature measuring device which provides a true volume weighted average temperature using a volume input signal and a temperature probe input signal. The microprocessor controlled TA-500 automatically calibrates the temperature probe each time temperature is sampled using two internal precision references. This technique eliminates both temperature drift and the requirement for field calibration since the probe temperature is calculated using a ratio of the probe and internal references in lieu of a fixed voltage or current level. Probe temperature, input counts, total temperatures, average temperature, reset totals and alarms are displayed on the unit's LCD display. An internal lithium battery preserves all data and alarms during main power failure and continues normal operation when power is restored. A fail safe alarm relay is provided to shut down external equipment in the event of alarms, microprocessor failure, probe failure or power failure.
