The TSP-EIS is a Standard sensor and the TSP-DIS is
an intelligent BriteSensor.® These sensors are used to
detect the presence of liquids in the normally dry interstitial
(annular) areas of double-wall fuel storage tanks (a Class
1, Division 1, Group D Hazardous Area). Both types of
sensors use electro-optical technology (LED & Prism) for
liquid-detection.
Figure 1: TSP-DIS and TSP-EIS Dimensions
The TSP-EIS communicates its identication code and
current detection status to the ATG console (water present
or normal – no liquids detected). An open-circuit is
recognized as an alarm-condition at the intrinsically safe
(I.S) leak detection circuits of the FFS (Franklin Fueling
Systems) ATG (Automatic Tank Gauge).
EYS Seal ttings and Epoxy to ll the tting after •
operational testing is completed.
Weatherproof junction box, gasket, and cover, plus a •
3/4 to 1/2 inch NPT reducing bushing if 1/2 inch RMC is
used – see the ATG Installation Guide for recommended
electrical junction boxes.

Black or Alpha Cable # 58113, 0.131 O.D. – 1,500 feet
(457 meters) maximum length. Alpha cable #58113
(INCON P / N 600-0063) must be used when using
nonmetallic (PVC) conduit.
Slip joint pliers to seat the no-strip, self-sealing wire •

Thread UL approved sealant or pipe dope as required •
for installation in UST interstitial areas (Figure 2).

The TSP-DIS sensor is enhanced with conductivity
sensors and a small microprocessor which allows it to
discriminate between water and product. The TSP-DIS
also communicates its identication code and current
detection status to the ATG console (water present,
product present, or normal – no liquids detected).
Both sensors are supplied with no-strip electrical wire
connectors, 25 feet of cable, a Model ID tag, and a cordgrip tting for connection to a weatherproof electrical
junction box (see diagrams).
Testing the Sensors
Dip the tip of the sensor in a clean cup of water – a
standard sensor alarm is generated for a TSP-EIS sensor
and a water alarm is generated for the TSP-DIS sensor.
When dipped in isopropyl alcohol, the TSP-DIS sensor will
produce a product alarm.
Test sensors on a yearly basis, or more frequently — per
local code.
Materials Required
Optional – TSP-DB1 Epoxy Seal kit for no-strip electrical •
connectors – recommended for sites: within ood zones,
high groundwater tables, with poor drainage, or when
Junction Boxes are not used.
1/2 or 3/4 inch NPT (National Pipe Thread, tapered), •
Rigid Metal Conduit (RMC) or nonmetallic (PVC) conduit
if allowed by local codes.

* TSP-KI2 Riser Cap for 2-inch riser pipes, includes a •
pre-installed 1/2 inch NPT compression gland (cord grip)
tting. Other riser caps are available for different riser
pipe sizes – consult your factory rep.
* Riser pipe – 2 inch diameter (OD), threaded at one •
end (NPT-14) with all rough edges removed / deburred
from the inner edges.
