The Vent Line sensor continuously monitors vent line headers for ammonia and fluorocarbons. High concentrations of refrigerant gases in vent lines are warnings of system overpressure or leaking relief valves. Either can pose danger to employees and equipment. Wasted refrigerants are costly and can mean overtime labor and plant downtime. Designed to be installed in refrigeration vent lines, the VL sensor is supplied with a 2 in. cast steel "T", plug and nipple.

The sensor is embedded in a 2 in. forged steel bull plug and houses a four-point terminal strip for electrically connecting the sensor and preamp. The linear 4-20 mA output pre-amp is housed in a separate enclosure.

The Vent Line leak detector is designed to be electrically connected to and monitored by all Honeywell Analytics readouts or can send a signal directly to a PLC.

Vent Line solid-state sensors are broad spectrum devices and will sense other
vapors in addition to the target gas. Please discuss details of the application
with Honeywell Analytics, including other gases that may be present and
whether the vent line is discharging to atmosphere or water tank.
