Adjustment of sample and dilution air flow meters determines the dilution ratio. Concentrations displayed on the Sentry Controller must then be multiplied by the dilution factor to arrive at actual concentrations. SENSOR MOUNTING PRODUCTS 5311-00 Rainshield The Rainshield is mounted over the sensor head to protect 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 calibration gas can be delivered to the sensor with out removing the module from the duct. ACCESSORIES 5360-00 5394-00 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 module. 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. © 2002 Sierra Monitor Corporation 1991 Tarob Court, Milpitas, CA USA 95035 Phone: (800) 727-4377 Email: sierra@sierramonitor.com 408-262-6611 Fax: 408-262-9042 ...
