The Rohr CONTROLS™ TA-1000 Plus Temperature Averager receives pulses from a flow-measuring device such as a positive displacement (PD) meter. As each pulse is received, it measures the temperature, adds the temperature into a rolling counter, divides the total temperature by the number of readings, and displays the average flow-weighted temperature for the batch. The accumulated probe (pulse) count may be cleared to start a new batch.
Two fail-safe relay output contacts provide an alarm if a temperature probe fails, a temperature is outside the acceptable range, the processor fails or power is seriously depleted or cut off. If the TA-1000 Plus is equipped with analog inputs, the relay output will also signal an out-of-range input. If equipped with a net pulse output option, the device can be used to transmit a compensated volume to another device.
The TA-1000 Plus uses a single-thermistor probe that delivers highly accurate measurements without periodic recalibration. The device is available in a CSA-approved explosion-proof or weatherproof package and may be powered with a 120 VAC or an 8-30 VDC power supply. Single-channel and dual-channel versions are available.
Weatherproof Package Option:
The weatherproof TA-1000 Plus features a compact molded fiberglass-reinforced polyester enclosure with an easy-to-read LCD and display control switch mounted in the door. Three conduit hubs are installed in the bottom for wiring. An optional custody transfer lockout kit provides added security.
Users configure the device using three buttons mounted on the circuit board inside the enclosure. A reset button for clearing probe count, alarms, and analog input averages is also provided on the circuit board. The display provides a real-time readout of process temperature measured by the probe, average temperature, total counts, counts per hour, and alarm count.
