Veeder-Root Sensor Application Guide <br /> interstitial Sensors for Steel Tanks <br /> The Interstitial Sensor for steel tanks detects the presence of liquid between the double walls of the tank. <br /> Sensor Detection Capabilities -Alarm Conditions <br /> • The presence of any liquid at a nominal height of 1 inch in the tank's Interstitial space triggers a Fuel Alarm. <br /> • An open sensor triggers a Sensor Out alarm. <br /> Operating Capabilities <br /> • Operating temperature range:0 to+70•C(for water),-20 to 700C (for hydrocarbons). <br /> • Storage temperature range:-40 to+700C. <br /> • Sensor dimensions:2.5"high, 1.5"diameter. <br /> Sensor Interface Module <br /> • TLS-350 Series Consoles(except TLS-350J)- Interstitial/Liquid Sensor interface module(P/N 329358-001) <br /> accepts up to 8 sensors(a maximum of 64 sensors could be monitored by the console). <br /> • TLS-350J Console-3 sensors max. <br /> • TLS-3001, PC-3001,TLS-300C,TLS-300J, PC-300C Consoles(no interface module required)-8 sensors max. <br /> • ILS-350 Console-A Two-Wire module(P/N 329675-001) accepts up to 4 sensors(a maximum of 16 sensors <br /> could be monitored by the console). <br /> • TLS-450-USM (P/N 332812-001)accepts up to 16 sensors <br /> Console Software Compatibility <br /> • TLS-350 sedes/TLS-300(Version 1 or later) <br /> • ILS-350(All) <br /> • TLS-450(All) <br /> Compatible Fuels <br /> • Unleaded gasoline <br /> • Unleaded with up to 5%methanol, <br /> 15%ethanol,or 15%MTBE 14"min.da. <br /> • Leaded gasolinemanhole Cord grip <br /> • Diesel <br /> • Kerosene r/' ^ <br /> • Jet fuel <br /> • 1/2'Aviation gasoline r <br /> Reducc er rSealroH <br /> Sensor/Cable Length Configurations (to cons conduit <br /> g g leader cable (to Console) <br /> • Interstitial Sensor with 16-foot cable- weatherprcorlunction <br /> threads <br /> V2-inch N.P.T. <br /> Form Number 794390-420 2•dia.dser tthreads(16 Cubic Inch <br /> volume minimum) <br /> • Interstitial Sensor with 30-foot cable- <br /> Form Number 794390-460 <br /> Accessories Sensor <br /> Riser cap and adaptor kit(0)- P/N 312020-928 Steel tank <br /> Related Sales Literature <br /> Sensor Switch must <br /> Visit our website at www.veeder.com for more rest on bottom of tank <br /> information on Veeder-Root products and services.
