| SHERLOCK VENTLINE
REFRIGERANT GAS SENSOR (VENTLINE) was
designed to detect the presence of high
concentrations of refrigerant gas in the
vent lines of refrigeration systems. The
sensor warns the user to investigate for
possible leaks in relief valve or to
check the systems for overpressure. The
sensor is designed to be installed in refrigeration vent lines and is supplied
in a NEMA 3R rated housing with 3/4"
NPT female connections. There are three
models of the Ventline Sensor, one for
CFC/HCFC gases, one for HFC gases, and
one for Ammonia. The Ventline Sensor
should be utilized as a signal source for
the SHERLOCK 2-SERIES or SHERLOCK
4-SERIES REFRIGERANT GAS MONITORING
SYSTEMS or the WIZARD EVAPORATOR CONTROL
SYSTEM.
Typical applications include:
- Monitoring of refrigeration
system relief lines
