No matter the need, Honeywell Sensing and Control (S&C) has the microstructure, pressure sensor solution. Our sensing element design consists of four piezoresistors on a chemically etched silicon diaphragm. A pressure change will cause a strain in the diaphragm and the buried resistors. The resistor values will change in proportion to the stress applied, which produces an electrical output. You will find our components performing in potential applications including :-

• Dialysis equipment, blood analysis, centrofusion and oxygen and nitrogen gas distribution, HVAC devices, data storage, process controls, industrial machinery, pumps, and robotics.
• Tire Inflator , Gas analyzing system
  
  

These switches sense a change in the pressure or vacuum and open or close an electrical circuit when the designated set point is reached.

Honeywell offers an impressive line:

• Electromechanical gauge pressure on/off pressure switches
• Single pole single throw (SPST) normally open or normally closed circuitry, or single pole double throw (SPDT) circuitry (pressure switches)
• Compatibility with a variety of media
• Compact size
  
  

Honeywell Humidity and Temperature Wall Mount Transducers, SCT Series, are an ideal environmental solution for indoor applications such as building automation and HVAC systems in residential and office buildings. The SCT Series offer a variety of options and features. The transducers can be equipped with or without a legible LCDdisplay which shows the ambient temperature along with the relative humidity or dew point. Standard output of humidity and temperature is either 4 mA to 20 mA or 0 V to 10 V. The temperature output signal may alsobe configured with an NTC 10 kOhm, 20 kOhm or PT1000 sensor.

Potential Applications Industrial
Climate monitoring and control for:

• Residential and office buildings
• Production and manufacturing plants
• Storerooms
• Equipment cabinets
• Testing environments

All airflow sensors operate on heat transfer — flow and differential pressure. Silicon chip design is created from thin-film, thermally isolated bridge structure, containing both heater and temperature sensing elements. This provides rapid response to the air or gas flow and amount and direction, delivering a proportional output voltage. Amplified versions provide an enhanced output signal and less external circuitry, while unamplified versions allow additional external circuit options.

Honeywell offers:

• Advanced chip design, manufacturing techniques and microstructure technology
• Enhanced response time and low power consumption
• Variety of port styles provide greater application flexibility
  
  

Honeywell offers electronic speed and position sensors designed for enhanced reliability and an extended life. We use multiple technologies to detect a change in magnetic field and create an electronic signal for control system interface. These technologies offer the ability to detect speed, direction, or position of a moving ferrous metal or magnetic target. Sensing is accomplished without contacting the target, and there are no moving parts. This eliminates mechanical wear of the sensor or target.

These high-speed, extended life sensors are often directly compatible with other electronic circuits, responding to the presence or the interruption of a magnetic field by producing a proportional output.
Today, the Honeywell S&C family of magnetic position sensors includes:

• Digital and analog Hall-effect position sensor ICs (operated by permanent magnet or electromagnet)
• Magnetoresistive sensor ICs
• Hall-effect sensor ICs)
• Gear-tooth sensors (sense movement of ferrous metal target))
• Magnets
  
  

Globally compliant and known worldwide for their compact and lightweight design, MICRO SWITCH™ snap-action switches are designed for accurate repeatability and extended life. MICRO SWITCH™ Basic switches are designed for presence and absence detection where physical contact with an object is permissible. They also excel in applications requiring simple on-and-off actions.

The Premium families of MICRO SWITCH™ Large and Subminiature switcheswere designed for high-precision applications where the cost of a switch failing is high. Originally developed to support United States aircraft in World War II, advancements in packaging and operating controls have helped further expand applications over the past 75 years while maintaining enhanced accuracy and repeatability.
