Control Systems

Junction Box and Control Circuitry

control-01This photograph shows a typical two barricade control circuit with an integral motor starter, electrical disconnect and step down transformer.

We build control circuits to project requirements from the simple to highly complex integrated systems, controlling multiple barricade systems. International voltages are available.

Hydraulic Power Unit – Skid Mounted for Big Equipment

control-05This is the top of the line, heavy duty, patented Delta Power Unit. We rack and stack valves, flow controls and accumulators to meet our client’s applications for speed of operation, number of barricades to be controlled and the number of power off cycles required.

The pump is supplied with an integral tank, sight gage and level switch. Options include hand pump and oil heater. The unit shown is a two barricade system pump.

Hydraulic Pump Control Equipment and Housing for Smaller Equipment

control-02Pictured is the patented Delta Beta pump, a scaled-down version of the Delta Power Unit. It is used for our medium to small barricades, depending on site conditions, barricade selection and speed of operation requirements.

H8050 DC Powered Pump

control-03Universal voltage DC powered versions (Model H8050) of these pumps are available for remote locations or infrequently operated barricades. They feature long battery life, low amperage trickle charging and solar panel charging.

Vehicle Loop Detectors

Delta Scientific’s NP series Digital Loop Detectors are recommended with all delta and most other vehicle access control systems because they are programmed to prevent a closing signal when power resumes.  NP Series Loop Detectors are directly interchangeable with most other brands as a plug-in replacement.

These loop detectors provide customers with a safety detector that can prevent accidents which occur when power outages cause vehicle access control systems to reset their logic. The 3446 NP Series incorporates an advanced micro-controller that combines a powerful digital computer and the latest and most advanced inductive vehicle loop technology to give high-test reliability and accuracy when measuring, counting or detecting vehicles.

This ability helps avoid unexpected gate operations such as the raising or lowering of gate arms, sliding gate operation, motorized teeth and barricade actuation. Delta highly recommends the use of vehicle loop detectors to prevent accidental closings and raisings when authorized vehicles move through vehicle access control systems which can suppress the operation of heavy gates and vehicle barricades.Typical digital loop detectors hold a gate open until the last part of a vehicle has passed the closing loop, located beyond the gate.

The detector then gives a pulse on departure, instructing the gate to close after the vehicle has passed. Oftentimes, after power outages, the entire system needs to be reset. The NP Series negates this problem.

Delta NP Series Loop Detectors provide input voltages of 24 VAC, 24 VDC, 120 VAC and 230 VAC.
