Bray Electro-Pneumatic Positioner (Series 6A)

Description

Bray International Electro-Pneumatic Positioner (Series 6A) features:

• Online Adaptive Control: During operation, the unit continually optimizes control behaviors and travel times in response to changes in line media pressure.
• Diagnostics:  Every electro-pneumatic positioner features corrective and preventative maintenance self-diagnostic checks. All diagnostics run constantly, may be continually monitored, and recorded.
• Air Supply Monitor: An additional feature of the Series 6A is an internal monitor that transmits a fault signal alarm if the air supply fails. The alarm is shown locally on the LCD and may be sent to the remote control panel.
• Local Position Adjustment: Valve position can be manually adjusted locally by removing the housing cover, then using the push buttons to override the remote command signal.
• Flow Restrictors: Precise control of even the smallest pneumatic actuators through internal flow restrictors.
• Position Indicators: In addition to the LCD display, valve position is clearly shown over a distance by a yellow indicator.
• Locking Device: For high vibration applications, the Series 6A features, as standard, a friction clutch locking device.
• Auto Calibration: Calibration is easily performed by entering only three parameters into keypad push buttons. The less than 5 minute calibration process automatically determines the position of the travel limit stops, then measures and records the parameters for both the open and close positions.
• Explosion Proof Housing: Designed for hazardous and severe applications, Series 6A explosion proof positioners offer all the features of the waterproof units in a flame-proof enclosure.
