DESCRIPTION

Device destined to protect gauges, pressure switches, pressure transmitters and others critical and expensive instruments against overpressures that could damage it. When, for any cause, pipeline pressure exceeds the maximum admitted value by the instrument, the limiter isolates it automatically from the circuit.

FEATURES

• Easy installation.
• Low gap.
• “Dry” spring, the fluid does not touch it.
• Six standard ranges of pressures.
• Continuously changeable outer calibration between limit values of each range.
• Upon request it could be delivered calibrated to the requested value and with its respective identification.
