*Evaluation performed by Carnegie Mellon Institute.
**Dual Stage Hydrostatic Sensor 794380-302 was replaced by Sensor 794380-303 and is not supported by TLS-450 series console.
***The "high" and "low" refer to high
and low level alarm points of dual stage hydrostatic sensors.
Comments:
EMC Series and EMC Basic controllers have been
evaluated only for use with sensors 794380-301 and 794380-303.
Evaluator reports that sensors will respond to any liquid
after their thresholds are exceeded.
Response times measured from trigger point, except for sensor
794380-301 with 50% by weight ethylene glycol in water, where
response time also included time for liquid level to rise
from bottom of a test cylinder to trigger point.
Evaluator reports sensors can easily be removed, cleaned,
and reinstalled after an alarm was triggered or for periodic
testing.
Sensors are reusable.
Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative sensors.
The TLS-4 8601 Series consists of the following derivatives: TLS-4, TLS-4B, TLS-4c, TLS-4i, and TLS-S1 consoles.
TLS-4 8601 Series testing did not include testing with ethylene glycol . Evaluator expects comparable results from previous testing with other consoles listed.
Single Stage Hydrostatic
Single Stage Hydrostatic Sensor 794380-301:
Intended to monitor level of either ethylene glycol or
calcium chloride solutions in interstitial or annular space
of a double-walled tank.
If the brine level in the reservoir drops below the threshold
of the sensor, an alarm condition is generated.
The evaluation using 30% by weight calcium chloride in water
was reevaluated using a different approved test protocol.
Dual Stage Hydrostatic Sensor 794380-302:
Alarm is activated if any significant gain or loss of
solution occurs.
Dual stage hydrostatic sensor 794380-303 has replaced this
sensor and is fully interchangeable with this sensor.
Vendor will discontinue production of this sensor as of December
31, 2003.
Dual Stage Hydrostatic Sensor 794380-303:
If brine level in reservoir drops below the threshold
of low-level sensor or if any liquid rises above the threshold
of high level sensor, an alarm condition is generated.
Alarms are indicated by an audible alarm, displayed message
on the console, printed message (if the console is equipped
with a printer), and recorded as part of the console “Alarm
History Report.”
