' ;� — Two sensors are required to monitor pressure across �� coils, filters, and blowers. A-301-K and A-302-K have four radial sensing holes and a 4" (10.2 cm) insertion �� ,- r'. depth. The A-308-K should be used only where accura- � °�-����"�� - cy is not critical. All mount in a 3/8" hole in the duct. If the interior of the duct is not accessible, an optional A- A-306-K 345-K flange mounting kit may be used. �� `��''� �, A-345-K Room Static Pressure or Total Pressure Sensgr Kit � � � The versatile Model 60681 Pressure Sensin Kit is used for monitoring static pressure (aspiration) or total ��_ � �``-'' �'�, pressure (impact). The kit includes a 7" (17.8 cm) univer- A-302-K A-301-K 21121 A-308-K sal sensing probe, adjustable mounting flange, 1/4" TYPICALAPPLICATIONS adapter, and 3 ft (0.9m) length of tubing (1/4" ID x 3/8" OD). For total (impact) pressure applications, install the �� � � curved tip opening facing into the air stream or away from the air stream for vacuum applications. � Total Pressure Sensor � Model 21121 Sensor is used primarily for proving air- O � � � flow in ducts.

Mount the sensor directly to a wall or ceiling using a �� standard electrical box. Model RPS-W is designed with � a white plastic wall plate and can quickly be installed using a standard electrical box. The Model RPS-I (not shown) is available with an ivory face plate. � Filter Kit Model A-605 Filter Kit includes an aluminum surface � mounting bracket and screws, two 5 ft lengths of 1/4" Rpg_W RPS SD-01 aluminum tubing, two static pressure tips, and two plas- tic vent valves. Surge Dampener Surge Dampeners absorb rapid pressure fluctuations in order to steady a pressure signal. Each surge dampener has two independent channels — one for the low-pres- �. sure tubing and one for the high-pressure tubing. Surge dampeners are typically used with outdoor pressure sen- � sors, which are subject to wind gusts, isolation rooms, clean rooms, or operating rooms where opening or clos- � ing doors creates sudden pressure changes.
