• Hazardous
Duty Edge Detectors
— Stahl Intrinspak®
safety barriers limit the amount of electrical energy that can flow into
the hazardous environment through the edge detector cables. Energy is
limited to a safe level that cannot ignite flammable gas, dust, or vapor
mixtures. |
| • Hazardous
Duty Purged Actuators — The purge system continuously circulates
clean air through the actuator housing and cable. Positive pressure
prevents the accumulation of flammable or combustible mixtures around
the actuator motor and cable wiring. A separate return duct and pressure
sensor continuously monitor airflow and shut off actuator power in the
event of a leak. |

Intrinsically-safe
dynamically compensated edge detectors |
 |
• Hazardous
Duty Explosion-Proof Actuators — These actuators use explosion-proof
motors to safely contain accidental combustion of gases or vapors within
the motor housing. Available with a brushed DC motor or a
high-performance brushless AC motor. |

Accuracy and Reliability — Dynamically compensated edge detectors
continuously adapt to changing environmental conditions and build-up of
contaminants on the sensors. Eliminates maintenance headaches caused by
constant cleaning and recalibration.
|
• Operator
Friendly
— Intuitive operator interface with touch pad and LED indicators.
The system configuration keypad is located inside the system enclosure,
safe from inadvertent adjustments.

• Network Friendly — Optional fieldbus adapters easily interface
with most popular fieldbus networks, including ControlNet™, DeviceNet™,
Modbus Plus, Profibus®-DP, and Ethernet protocols. Discrete I/O
interfacing is a standard feature. |
