Application
The 4285-9B inertrol alarm gauges are designed to alert the
user when pressure has fluctuated ±90 PSIG from the 300
PSIG factory setting. Under these conditions, electrical
contacts in the switch will close and set off a user-furnished
alarm system.
Features
• Solid brass gauge casing resists corrosion and provides
for longer life.
• Equipped with a heavy-duty, 36” long, 3-wire electrical
cable.
• Each gauge is factory pre-set at 300 PSIG, then sealed to
help prevent against tampering once in service.
• Electrical circuit is rated for a maximum of 3 AMPS at 460
volts AC.
