Force Sensors

Force sensors operate on the principle that the resistance of silicon implanted piezoresistors will increase when the resistors flex under any applied force. The sensor concentrates force from the application, through the stainless steel plunger, directly to the silicon sensing element. The amount of resistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level.

Mass Airflow Sensors

Mass Airflow sensors contain a thin-film, thermally isolated bridge structure that contains both heater and temperature sensing elements. The bridge structure provides a sensitive and fast response to changes in airflow or other gasses over the chip.

Silicon Pressure Sensors

Honeywell silicon pressure sensors are small, low cost, and reliable. They 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. 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.

OEM Pressure Sensors

Honeywell pressure sensors range from miniature surface mount sensors to high-end stainless steel isolated transmitters used for stringent process control. Using Honeywell products promotes exacting, reliable and cost-effective sensor solutions. So, whether your application calls for low pressure measurements in inches of water or measurements up to 25,000 psi, you can trust Honeywell to help you handle the pressure.

Oxygen Sensors

Sensors employ two ZrO2 discs with a small hermetically sealed chamber in between. One of the discs functions as a reversible oxygen pump, which is used to successively fill and empty the chamber. The second disc measures the ratio of the partial pressure difference and generates a corresponding sense voltage. A heat element produces the 700 °C required for the ZrO2 to operate as an O2 pump. The time taken for the pump to achieve specific minimum and maximum pressures within this chamber is a measure of the partial oxygen pressure of the environment.
