Image is Representational - See Manufacturer Specs | Pressure Sensor 0psi to 100psi Differential/Gage 6-Pin Pressure sensors, also known as pressure indicators, are instruments that are used to measure the pressure of gases and liquids. They can also be used indirectly to measure the flow of fluids and gases, speed, water level and altitude, as well as other variables. These instruments are generally used in medical equipment, barometry, computer peripherals, pneumatic controls, and HVAC equipment.SCX100DN Pressure Sensor from Honeywell is an internally calibrated and temperature compensated sensor. This Honeywell Board Mount Pressure Sensor is ideal for use with air and dry gas, as well as with non-corrosive, non-ionic working fluids. Featuring an integrated circuit sensor element and a laser trimmed thick film ceramic in a compact solvent resistant case, this low power sensor ensures a long operating life.
