Overview
The TSP-DVS sensor is an intelligent BriteSensor ® that
is used to detect the presence of hydrocarbon vapors
(product). The sensors are installed suspended above
the highest recorded ground water table (level) in 4 or
2 inch monitoring wells around tanks. The sensors use
intrinsically safe (I.S) leak detection circuits and are rated
for use in Class 1, Division 1, Group D Hazardous Areas.
Three types of sensors are integrated in the TSP-DVS: a
vapor sensor to detect hydrocarbon vapors, conductivity
electrodes to detect water (submerged sensors can’t
detect product vapors), and a temperature sensor (to help
minimize false alarms).

Like other BriteSensors, the TSP-DVS sensors have a
microprocessor that analyze the environmental conditions
at the sensor and transmits this data to the Automatic
Tank Gauge console. TSP-DVS sensors detect and
communicate: a WATER alarm (from the conductivity
sensors), VAPOR present (from vapor & temperature
sensors), and a NORMAL no-alarm state (hydrocarbon
vapors are not present and sensor is not in water), plus it
transmits a specic sensor ID code.
No-strip electrical wire connectors, 25 feet of cable
attached to the sensor, a Model ID tag, and a cordgrip tting (for connection to a weatherproof electrical
junction box) are supplied with the TSP-DVS sensor (see
diagrams).
Installation Sequence
1. Install sump.
2. Install conduit, EYS ttings, and weatherproof
junction box.
3. Shut off power.
ELECTRICAL DANGER Avoid electrical
shock hazards: ensure all power
going to the ATG console is turned off,
tagged, and locked-out at the power
panel before doing any maintenance or
installation work at the ATG console.
4. Install the sensor cable through the supplied
compression tting.
5. Install the compression tting at the waterproof
junction box and tighten the cord-grip tting.
NOTE Do not cut / trim the sensor cable because it must
be removed and tested occasionally outside in the
open air (coil up cable).
6. Trim wire / cables at the junction box to a 6 or 8
inch length (15 or 20 cm) or service-loop, and
splice the sensor and console wires together per
Figure 3. Before pulling wires, mark them to avoid
confusion when connecting to the ATG.
7. Turn power on to console to test sensor.

Caution
Caution
(verify that no alarm is produced at ATG console),
if it doesn’t produce an alarm then seal EYS seal
ttings and the optional TSP-DB1 epoxy seal kit
for electrical connectors with epoxy.
9. Turn power off again if other devices are to be
installed (Repeat Step #3).
10. Install the TSP-DVS sensor in the well screen
pipe and latch the riser cap (refer to Figure 2).

A junction box may be used inside of the building and
used as a I.S. pull box to combine several sensor cables.
If this is done, then only one I.S. conduit knockout may
be used at the console. Before pulling wires, mark them
for identication to avoid confusion when attaching to the
console.

with NFPA 70 (National Electric Code)
and NFPA 30A (Automotive and Marine
Service Station Code). Failure to seal
conduits in accordance with NFPA 30A,
and NFPA 70 could allow ammable
vapors to travel through the conduit in
the ATG console. An explosion could
result causing serious injury, property
loss, or death.

11. Reinstall all safety covers and guards, junction

tting threads.
12. Install the manhole cover.
13. Record the location where the sensor was
installed (Sensor channel # , and other data ) on
the chart on the back page of these instructions.
14. Turn power on and program the ATG. Refer to
Sensors in the Setup / Programming & Installation
manuals. Additional steps for programming this
sensor are shown on the next page.
General Installation Notes
WARNING It is the installer’s
Warning
Plan your conduit routing. Dig trenches as necessary to
install conduit from each junction box to the Intrinsically
Safe (I.S.) knockouts at the ATG console. You must install
a weatherproof, electrical junction box inside each sump.
Access to sumps must be done so all entries are liquidproof (to keep product in the sump if a spill or leak occurs).
The junction box should be installed high on the sidewall to
prevent it from being submerged during heavy rains.

Testing
To test operation of the TSP-DVS, remove the sensor
from the well and place it in a high-vapor environment
(i.e. a mostly empty gas can). The tank gauge should
show a high-vapor alarm. (Do NOT immerse the sensor in
gasoline)!
Remove the sensor and set it in open air. The vapor
reading should drop.

Under setup / 3-wire Modules, assign unique names for the sensors
The Vapor reading indicates the normal vapor level in the space being monitored. Under FMS / Control / Sensors, set the
vapor offset to a value that will trigger a vapor alarm. Typical values are between 200 and 300. The presence of signicant
vapors will create a drastic increase in the vapor reading.
