Linco-Electromatic, INC | Electronic Devices | TA-500 Temperature Averager

DESCRIPTION

The TA-500 is a 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 proven 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, flow rate and alarms are displayed.

An internal lithium battery preserves all data and alarms during battery power failure and continues normal operation when power is restored. A failsafe alarm relay is provided to shut down external equipment in the event of power failure, alarms, probe failure or microprocessor failure.
