Specificity Results:
Evaluator
claims both 794380-343 and 794380-344 sensors will respond in any liquid after
the sensor threshold is exceeded.
Sensor 794380-343 is designed to discriminate between product and water.
Separate alarms are designed to be triggered for product and water.
Manufacturer’s Specifications:
Sensors
794380-343 and 794380-344 can be removed, cleaned, and reinstalled, for periodic
testing, if an alarm is triggered or if service is necessary.
Sensor 794380-343 has no moving parts.
Sensor 794380-344 can be easily removed, cleaned, and reinstalled if an alarm is
triggered or for periodic testing.
Sensor 794380-344 is designed for use in contained risers and the interstitial
space of double-wall steel tanks. When product or an open sensor (referred to
as “Sensor Out”) is detected, an audible alarm is actuated, a message is
displayed on the TLS-350 or TLS-350R console, and a printed message is generated
if the console is equipped with a printer. The alarms are also recorded as part
of the TLS-350 or TLS-350R “Alarm History Report”.
Comparison of TLS-450 with TLS-350 series console showed comparable results when
evaluated with representative sensors.
