Sample Draw Products

ACCESSORIES

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.

5399-01 Sample Draw Fitting

The sample manifold assembly is the 5399-01 Sample Draw Fitting. Sample stream draw and flow control is pro- vided by the user.

5398-01 Sample Draw Assembly

The 5398-01 is a complete sample draw assembly includ- ing the sample draw fitting, driver air, sample and exhaust fittings and flow metering assembly. This allows accurate adjustment of sample flow using the signal flow meter lo- cated on the flow metering assembly.

5398-02 Sample Draw/Dilution Assembly

The 5398-02 is used in applications in which the expected gas concentration is either higher than the maximum range of the sensor or sufficiently high to significantly reduce sen- sor life with extended exposure. This assembly adds a second flow meter for control of dilution air. Adjustment of sample and dilution air flow meters determines the dilu- tion ratio. Concentrations displayed on the Sentry Con- troller must then be multiplied by the dilution factor to ar- rive at actual concentrations.

SENSOR MOUNTING PRODUCTS

5311-00 Rainshield

The Rainshield is mounted over the sensor head to pro- tect the sensor from direct exposure to rain, hosedown and other splashing liquids.

5394-00 Duct Mount Fitting

The Duct Mount Fitting facilitates installation of the gas sensor module onto an air duct. The fitting also includes the 5360-00 calibration gas delivery fitting so that calibra- tion gas can be delivered to the sensor with out removing the module from the duct.

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.
