The Precision Controls Division (PCD) of Marsh Bellofram Corporation has announced the global market introduction of Type 3110 and Type 3120, a series of single- (3110) and double-loop (3120) electro-pneumatic analog circuit-card servo pressure transducers, designed to provide compact, high-performance, economical air pressure monitoring capabilities within a variety of OEM applications. Occupying an overall footprint of 50.8 mm by 71.12 mm, Marsh Bellofram Types 3110 and 3120 offer user-selectable, configurable (zero and span) industry standard zero to 10 VDC or 4-20 mA control signals, with custom signal outputs available upon request. Industry-standard analog monitor output signals are available for user monitoring of actual output pressure. Industry-standard logic output signals (high or low) are also available for user monitoring of set point status. Two manifold block configurations are available, one with front ports to facilitate direct panel mounting or seamless insertion into a DIN-rail adapter tray; and the second with bottom ports, facilitating use within multi-unit manifold system applications. An onboard pressure transducer within the manifold block permits ±0.5 percent full-scale accuracy. Custom multi-unit manifolds are also available upon request. Typical applications include damper control, gas chromatography, process control and medical equipment, such as ventilators and blood analysers.
