New approach to the monitoring of critical pressures

The One Series Threshold Detection Switch has monitoring functions traditionally performed separately by transmitters, switches and gages. The device features fast switch response on either rising or falling pressure, and handles pressure ranges to 6,000 psi. Setpoint and deadband are adjustable to cover the full operating range. Designed to meet the needs of critical alarm and shutdown systems, the series offers a solution for the redundancy and alternative technology requirements of safety standards such as ANSI/ISA S84.01 and IEC 1508. The product communicates its health (IAW) and the state of the switch over a standard two wire discrete digital connection. If analogue trending data is needed, an optional 4 to 20 mA analogue out-put can be added. A digital display provides both a real time indication of process pressure and a means for operator field adjustment of setpoint and deadband. Bench set versions are available. The series employs solid state technology with no moving parts and is approved for use in Class I, Division 2 hazardous locations by UL for U.S. and Canadian installations.
