Appendix 3: 3-Wire Sensor Module (3WSNS)
The 3-Wire Sensor Module (3WSNS) is designed to accept 8
sensor inputs per module, and the system as a whole can accept
a total of 24 sensors (3 modules with 8 inputs each). The 3WSNS
can support standard sensors and BriteSensors ® . BriteSensors
are powered sensors that digitally communicate the sensor–type
and alarm status of the sensor to the console. Most BriteSensors
can discriminate between water and hydrocarbon products and
produce different alarm codes for each. Refer to the diagram
below to identify the types of sensors that should be used with this
module.
Important: Brite Sensors are not approved for use in European Union markets where ATEX approved devices are
required.
Most of the Brite Sensors shown in this table are part of the UL & C-UL System Listing.
Model Description
TSP-EIS Electro-optical Interstitial liquid – Standard sensor
TSP-ULS Universal Liquid – Standard sensor
TSP-HLS-15 High product Level, 15" – Standard sensor
TSP-HLS-30 High product Level, 30" – Standard sensor
TSP-HIS Hydrostatic Interstitial reservoir – BriteSensor
TSP-HIS-XL* Hydrostatic Interstitial reservoir, extra long – BriteSensor
TSP-DIS Discriminating Interstitial liquid – BriteSensor
TSP-DDS Discriminating Dispenser Sump – BriteSensor
TSP-DTS Discriminating Turbine Sump – BriteSensor
TSP-DVS* Discriminating Vapor – BriteSensor
TSP-MWS Discriminating Monitoring Well – BriteSensor
* TSP-HIS-XL and TSP-DVS sensors are not covered by UL and cUL approval.
Note: Alternate sensors may be provided. All components located in the hazardous area must be Third Party Certified
and have appropriate Entity Parameters (see Control Drawing 000-1722 in the back of this manual for further
information).
