Volume Boosters increase the flow capacity of electro-pneumatic transducers, leading to faster response time and increased ability to remain at setpoint.
Low-flow transducers (T3210, T3220, T3510, and T3520) can be mounted on the volume booster of your choice. Simply add the booster’s 2-letter code (from below) to the Options field of the T3000 part #.
The RPS sensor can be used with two-loop transducers (T3120, T322X, T3420, and T352X), closing the loop to the booster’s output and increasing overall accuracy.
When the distance between transducer and volume booster is large (e.g., when the transducer is mounted in a cabinet and the booster is installed directly at the application), one of the high-flow transducers (e.g., T3211 or T3512) can drive the booster over distance.
The X booster is the Marsh Bellofram Type 20EXHR. It utilizes two-stage technology to maintain setpoint over a wide range of flows (Note: minimum output is 2 psig/0.14 BAR). The Z booster is the Marsh Bellofram Type 75HR. The N booster is the Marsh Bellofram Type 79. Consult the documentation for these products for more information.
The Q boosters are ultra-high flow boosters. The V booster can be used with vacuum versions of the T3210, T3220, T3510, and T3520.
Flow capacities are for comparison purposes only. Forward flow is typically measured at 100 psig (6.9 BAR) supply and 80 psig (5.52 BAR) output. Exhaust flow is typically measured at 5-10 psig (0.35-0.69 BAR)above 20 psig (1.38 BAR) setpoint.
