DIFFERENTIAL PRESSURE INTRODUCTION S etra is a leading manufacturer of a broad portfolio of pressure transducers, humidity transmitters, current switches and current transducers. The company was founded in 1967 by Dr. S.Y. Lee and Dr. Y.T. Li, former Professors of Engineering at the Massachusetts Insititute of Technology.
Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure. The diaphragm is constructed of a low-hysteresis material such as 17-4 PH SS or a proprietary compound of fused glass and ceramic (Setraceram).
DIFFERENTIAL PRESSURE Absolute Pressure — Pressure measured relative to full vacuum. Referred to as pounds per square inch absolute (PSIA). Atmospheric Pressure — Pressure of the atmosphere at the earth’s surface NIST standard atmospheric pressure = 1.01325 bar. BAR — Unit of pressure (or stress). 1 bar = 750.07 mm of mercury at 0°C, at 45°. Barometric Pressure — Atmospheric pressure, often measured in millibars, in Hg (inches of mercury), or hectopascals.

power monitoring DIFFERENTIAL PRESSURE Patrol Flex Rogowski Coil DESCRIPTION The Setra Patrol Flex is an AC current probe utilizing the Rogowski principle. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas, without batteries or an external power source. Setra Patrol Flex is available as a 3-pack, perfect for use with 3-phase power applications. The Flex clamp fits around bus bars and large or hard-toreach conductors.
Current Transformers DESCRIPTION Split Core Standard CTs provide linear output voltage that is directly proportional to the input current. These current transformers are safely and easily installed over existing electrical power lines without disconnecting the lines or interrupting service.
power monitoring DIFFERENTIAL PRESSURE Split Core Performance CT Current Transformers DESCRIPTION The hinged Split Core Performance CTs are small, low cost current transformers with high accuracy over a wide dynamic range with excellent phase shift. These CTs are ideal where space is limited such as when metering multiple loads within a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and submetering.
