Our Products #4956873

Single point sensors used in numerous top-loading applications such as rail cars and hazardous liquid tank vehicles.Intended for use with Scully overfill prevention control monitors- (ST-15 models) which feature Dynacheck circuitry that monitors the sensor, wiring, connections and its own operation 30 times per secondSensor is inserted into the tank compartment and an adjustable clamp or coupling allows you to determine the sensing level and holds the sensor in placeWill not permit loading under any fault or wet sensor conditionsEach model has an adjustable clamp or coupling, depending on its intended useSpecific models available for unheated or heated liquidsAvailable in aluminum or stainless steelUnits with connection cables that detach from the rack location are also availableHang at the rack location or elsewhere when not in use

Tests for proper performance of all Scully terminal overfill prevention control monitorsEnsure that your Loading Rack Control Monitors are functioning properly and will allow properly equipped vehicles to loadFM & ATEX approvedSimulates Optic and Thermistor Overfill SensorsSimulates Scully Ground Bolts & Ground BallsSimulates Scully T.I.M. Truck Identification Modules

The most advanced terminal overfill prevention and ground verification system available.The only control system that offers overfill prevention, static grounding, and vehicle identification all-in-one unitThe ultimate in terminal loading safety with a patented design that continuously monitors the relay contactsfor petroleum and chemical loading racksIncorporates Dynacheck Dynamic Self Checking circuitry for overfill prevention, ensuring that every critical component is automatically and continuously checked for maximum loading safetyThis includes the control unit, wiring, and sensor circuitry, and should a fault be detected, it signals a loading shutdown to prevent product from overfillingOver 15 years of proven performance in the fieldthe number one choice worldwide

Multiple-Point, Optic-Sensing Overfill Prevention Control UnitInterfaces with five-wire optic sensorsUsed, typically for bottom and top-loading of tank vehiclesMounted at the loading rackgantry and connects to the vehicle via the Scully plug and cable assembly (sold separately).Features Dynacheck circuitry for automatic and continuous self-checking of all system componentsFor vehicle groundearth verification options, consult Scully for information on the Groundhog Self-Proving Grounding System.

Protect your investment in controllers, wiring, and cablesRecover from a drive-away in minutes without an electricianChoose between a short Break-Away Plug and Cable close to the vehicle or a longer Pull-Away Plug and Cable connected near the terminal junction box

Pull-Away Plug and Cable Assembly from Scully eliminates your down time as a result of tank trucks driving away with the overfill plug still connected to the vehicle. The plug and cable detaches from its junction box without damage to the connection of the overfill monitor. Also, as a handy spare it allows you to keep the rack operating while troubleshooting for broken connections.Protects the truck socket, cable assembly and rack controller.Will not separate at forces encountered during normal operation.Recover from drive-off in minutes without an electrician.

High-level detection in each vehicle compartment, using either Scully Two-Wire or Five-Wire SensorsSystem shutdown within one-half second of high-level or fault condition detectionIndividual sensor indicators for static conditions such as wet sensor or operational faultsNew Five-Wire Series wired sensor compatibility adds diagnostic capability to five-wire vehicles.Detects opens, shorts, and helps pinpoint specific sensor to save time in troubleshootingDynacheck Safety Complete automatic and continuous checking of all system componentsComplete system diagnosticsVisual indication of Dynacheck self-checking, sensor status, and fault conditionsIndicator for auxiliary switch operation, such as vapor interlockLoading rack connection indicatorsRetained Product Monitoring Retained product detection using Two-Wire Optic SensorsLoading lock-out feature if vehicle returns with productDriver must press retained product acknowledge button for loading to occurHelps prevent product mixingWarns against overfilling of vehicle compartments

Vehicle Static Ground Verification SystemSelf-proving technology based on Scullys original patented designCan operate in conjunction with your Scully Overfill Prevention System (ST-35 or ST-15) or as an independent ground verification unitImmediately shuts down the loading operation if proper static grounding is not detected

Extremely rugged petroleum-resistant design which can withstand harsh environments and mishandlingPermanent socket locator pins that wont loosen or back outInternal cable retention clamp to prevent cable pull-out or twistingThe plugs and cables are the pathway for the control unit, sensor signals, ground bolt and T.I.M. Truck ID module which monitor the status of overfill prevention, electro-static grounding and vehicle identification during loading operations

Can be used with a variety of loading operations including tank trucks, rail tank cars, aircraft refuelers and tanks for an independent ground proving method without overfill prevention to ensure that transport vehicles are properly tied to ground before and during the loading operationThe ST-47 Static Grounding system continuously monitors the ground connection and if that connection is lost, the ST47 will non-permitFor static ground verification in conjunction with your Scully Overfill Prevention system, wire the ST-47 through your Overfill Prevention Control Monitor and plug and cable for one quick overfill protection and static groundingearthing connection; see Plug & Cable Assemblies for Overfill with Grounding CombinationsFor use with ST-47 Groundhog when it is wired through the ST-35 or ST-15 Overfill
