SAMPLE DRAW PRODUCTS
Sample draw products are used in applications in which the sensor cannot be installed directly at the gas sensing location due to poor accessibility or the harshness of the environment. Sample is continuously drawn from the sens- ing location to the sensor at a more suitable location.
The primary component of the sample draw product is a venturi manifold that uses a continuous flow of driver air to pull a slight vacuum through the sample supply line draw- ing the sample into the manifold cavity connected to the sensor.
The sample manifold assembly is the

SENSOR MOUNTING PRODUCTS
The Rainshield is mounted over the sensor head to pro- tect the sensor from direct exposure to rain, hosedown and other splashing liquids.
The Duct Mount Fitting facilitates installation of the gas sensor module onto an air duct. The fitting also includes the

CALIBRATION ADAPTERS
The Sentry system is designed for easy calibration of the sensor modules. The standard calibration adapter screws over the head of the sensor. Then calibration gas is fed through a tube connected onto the adapter.
Magnetic calibration adapters are commonly used with Sentry gas sensor modules. The magnetic calibration adapter is used to control a switch inside the sensor mod- ule. When the adapter is first applied to the sensor the switch closes to indicate the start of calibration and the zero gas stage. The second time the adapter is applied to the module, the switch closure indicates that span gas is being applied. When the magnetic adapter is removed, the module knows that calibration is complete and sends the appropriate signal to the controller.
