Marsh Bellofram Intros Servo Pressure Regulators
Pressure monitoring sensor.
Newell, WV — The Precision Controls Division (PCD) of Marsh Bellofram Corporation has introduced its Type 3110 and 3120 series of single- (3110) and double-loop (3120) electro-pneumatic analog circuit-card servo pressure transducers. The transducers are designed to provide compact, high-performance, economical air pressure monitoring capabilities within a variety of OEM applications.
Occupying an overall footprint of just 2 x 2.8-in. (50.8 x 71.12mm) and with available analog monitor output ranges from 29-in. Hg to 600 psig, The new transducers offer user selectable, configurable (zero and span) industry standard 0 to 10VDC or 4 to 20mA control signals, with custom signal outputs available0. 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 — either "at set point" or "still searching".
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.
The new regulators are suitable for size-conscious OEMs looking for air pressure monitoring without sacrificing any of the high-end capabilities normally associated with full-size I/Ps. Typical applications include damper control; gas chromatography; process control; and medical equipment, such as ventilators and blood analyzers.
