PRESSURE SENSORS

Pressure Sensors

Honeywell has over 40 years of experience in the pressure transducer industry. We offer three pressure sensor measurement types - absolute, differential and gage - including vacuum gage and bidirectional types. A wide variety of pressure ranges, along with both amplified and unamplified versions, are available. Silicon-based versions in stainless steel and brass housings allow for use in harsh environmental conditions. A wide choice of mounting, package, and port configurations allows customers to choose from standard off-the-shelf designs.

Pressure sensors contain sensing elements that consist of four piezoresistors buried in the face of a thin, chemically-etched silicon diaphragm. A pressure change causes the diaphragm to flex, inducing a stress or strain in the diaphragm and the buried resistors. The resistor values change in proportion to the stress applied and produce an electrical output.

All Honeywell pressure sensors feature excellent repeatability, high accuracy and reliability under varying environmental conditions. In addition, they feature highly consistent operating characteristics from one sensor to the next and interchangeability without recalibration.

Stainless Steel versions

Honeywell also offers stainless steel pressure transducers that use bonded strain gauge technology with stainless steel media isolation, which eliminates the need for internal seals. Our stainless steel pressure transducers utilize bonded semiconductor strain gauge technology and are designed for demanding environments involving corrosive media. They are manufactured in a variety of packages that are widely used in medical equipment, compressors, hydraulic controls, transportation, agriculture, and refrigeration applications. Laser trimmed and tested, they are fully calibrated and temperature compensated to assure long-term reliability and performance. Stainless steel pressure transducers are fully compensated to eliminate known sources of errors.

Most of our transducers utilize the ‘bonded strain gage’ technology and are fully stainless steel media isolated, eliminating the need for internal elastomer seals. Our strain gage design is very resistant to the effects of shock, vibration and hostile environments. All of our transducers are fully compensated and tested against the appropriate specifications before shipment.

High Purity versions

High purity pressure sensors are focused on high-purity applications in the wafer-processing segment of the semiconductor industry. With ISO 9001 certified facilities and Class 10 cleanroom capability, Honeywell manufactures a full line of high purity pressure sensing and control products; each individually tested, inspected and certified to be in full compliance with the product specification.

The long life of the high-purity pressure sensors, coupled with long-term stability, greatly reduces or eliminates the need for zero and span adjustments.
