Leak Detection Sensor – Cleaning & BriteSensor™ Recovery
W h a t t o d o F i r s t :
• Identify and/or chemically analyze the liquid detected and repair the source of the leak ( be sure to
follow all environmental rules, regulations, procedures and reporting requirements ).
• Pump the fuel / waste water mixture into an approved containment vessel and clean the area with
absorbent pads ( follow disposal regulations & safety precautions ).
• Remove and clean the exposed sensor. In the case of several types of BriteSensors, replace it with a
new or recovered sensor (see Applicable BriteSensors with reactive strips below).
INCON BriteSensor Cleaning & Recovery:
All BriteSensors can detect two or more alarm conditions. Most BriteSensors can also discriminate between
petroleum products and water (except the TSP-HIS Hydrostatic Interstitial Sensor). When a liquid or
condensed hydrocarbon vapor comes in contact with the sensor, the dark orange strip inside of the sensor
swells / expands, which causes it to enter into a
PRODUCT alarm state. Do not discard BriteSensors that are in
a product alarm state — they can be reused after cleaning and adequate recovery.
Applicable BriteSensors with reactive strips:
TSP-DDS (Discriminating Dispenser Sump Sensor)
TSP-DTS (Discriminating Turbine Sump Sensor)
TSP-MWS (Discriminating Monitoring Well Sensor)
Approximate Recovery Times:
• 90 minutes for a 24 hour soak in gasoline
• 30 days for a 24 hour soak in diesel fuel
NOTES: Recovery is delayed by high humidity or low temperatures. Recoveries are also delayed
from prolonged or repeated hydrocarbon exposures, or from exposures to diesel fuel
Install a new / spare recovered sensor to maintain EPA compliance during recovery
(
Important when the sensor has had extended exposures or exposures with diesel fuel)
A BriteSensor IS NOT and WILL NOT be in a PRODUCT alarm state after it has recovered
(this can be verified by connecting / wiring it to a Tank Sentinel console
