Instruction Manual #122162 10
2. General Description
2.1 Part Names and Description
SENTRY 1510 is a mechanical-based process pressure exhaust controller. It is a pressure
regulator designed to respond to static exhaust pressure changes and process flow gas
changes in order to maintain a constant process pressure at the tool.
Nitrogen Supply Port accepts the Nitrogen supply from the tool or facilities required for
proper operation of the SENTRY 1510. A fitting accepting ¼” OD tube or pipe is provided.
Drain Port (plugged) provides a means for connecting a drain line to the SENTRY 1510
when a vertical upward flow configuration is installed. A ¼” FNPT port with plug is provided.
SENTRY 1510 Input Port provides a means for connecting the SENTRY 1510 to the
process exhaust output from the tool.
Flow Direction Arrow indicates the process exhaust flow direction and points from the tool
process exhaust to the facility exhaust.
Mounting Holes provide a means for installing the SENTRY 1510 to a support structure or
the process equipment. Four 10-32 thread holes are provided.
Interface Port accepts the TIM-100/120 to SENTRY 1510 interface cable which supplies the
appropriate power and signal communications to the SENTRY 1510 controller.
Sense Line Port accepts the sense line included with the SENTRY 1510. The tool process
pressure is measured by the internal pressure transducer. A Nitrogen purge is provided to
ensure long-term reliability.
Do NOT block the Sense Line Port when Nitrogen is turned ON.
Reference Port this port is not currently used on models supplied with this manual. A
limited number of models are available with the reference port operational to allow for differential
pressure control relative to a pressure other than atmosphere.
SENTRY 1510 Output Port provides a means for connecting the SENTRY 1510 to the
facility exhaust.
