Honeywell FSS1500NST Pressure and Force Sensor Amplifier
The Honeywell FSS1500NST is a circuit designed to amplify the millivolt output of Honeywell's MICRO SWITCH pressure and force sensors. The circuit employs operational amplifiers to achieve amplification, with options for single or multi-stage configurations to minimize common-mode errors. Honeywell recommends limiting amplification to 250 times and provides specific instructions for absolute sensor applications, including reversing pins 2 and 4. This solution is ideal for industrial applications requiring precise measurement of pressure and force.
