Comments:
Manufacturer states that Sensor 794380-304 is
installed near the bottom of a brine reservoir.
An alarm is triggered if the
brine level falls below the threshold level of the sensor.
Manufacturer also states that the sensor
withstands removal and replacement from the reservoir without damage to the
sensor.
The testing conducted for this evaluation determined the sensor’s response to
brine and propylene glycol.
The evaluator states that other liquids would also produce an alarm
if the sensor threshold is exceeded. These thresholds would be slightly
different for different liquids due to the differing densities. These liquids,
and the threshold for each, have not been determined at this time.
Comparison of TLS-450 with TLS-350 series console showed comparable results when
evaluated with representative sensors.
