Pressure Sensors measure pressure in 2 directions.
September 23, 2008 -
Available in PC board mount, NEMA 1, NEMA 4, and DIN rail mounting types, Capacitance Pressure Sensors measure pressure from 0.1-100 in. of water column with accuracy from 2% to 0.25% at room temperature. Outputs include 0-5 V, 0-10 V, or 4-20 mA. Some units can be temperature-compensated to 0.01% of full-scale/°F. Typical applications include HVAC, duct measurement, clean room control, fume hoods, critical containment enclosures, and isolation rooms.

New Capacitance Pressure Sensor Line Offered By Servoflo Corporation
Measures Pressure in Two Directions from 0.1 Inches to 100 Inches of Water
August 20, 2008
Servoflo Corporation of Lexington, Massachusetts is pleased to announce representation of the Alpha Instruments pressure sensor line. Made in Massachusetts, Alpha Instruments offers capacitance based pressure sensors which measure 0.10 in. to 100 in. of water column. All models have a bi-directional version, making them well suited for applications where 2 directions of pressure need to be measured. Typical applications include HVAC applications, duct measurement, clean room control, fume hoods, critical containment enclosures, isolation rooms, and other building management applications.
The Alpha Instrument sensors come in a variety of package styles, include PC board mount, NEMA 1, NEMA 4, and din rail mounting type. Outputs of the sensors include 0-5V, 0-10V, or 4-20 mA. In the voltage version, true zero can be achieved. Some units can be temperature-compensated to 0.01% of full-scale per degree F, a key advantage for requiring accuracy over temperature. The accuracy varies from 2% to 0.25% at room temperature. Alpha Instruments has a unique calibration method which allows users to have special pressure ranges for certain applications. For example, it is possible to create a range of -0.5 in. water column to +3.5 in. water column.
At 250 pieces, the price ranges from $90 to $150 each depending on the model and accuracy. With a 15 PSI overpressure, the Alpha Instruments line not only offers flexibility in their usage, but also ruggedness and reliability over the competition. All models meet CE and RoHS conformance requirements.
Servoflo is a provider of pressure sensors, accelerometers, electronic compass modules, and sensor signal conditioners for the automotive, medical, process control, and other industrial applications. For information on all of Servoflo's product offerings, please visit www.servoflo.com.
