What are capacitive pressure sensors?
When automotive ignition and carburetor systems initially required inputs from the engine to control spark and fuel and lower vehicle emissions, a capacitive pressure sensor was designed to specifically measure manifold absolute pressure (MAP) and barometric absolute pressure (BAP). Called a silicon capacitive absolute pressure (SCAP) sensor, it consisted of a micromachined diaphragm etched into […]
What is the difference between a gauge and an absolute pressure sensor?
Understanding the difference between gauge and absolute pressure sensing measurements is easiest to visualize with piezoresistive type pressure sensor and a diaphragm that deflects with pressure. For both types of measurements, pressure is applied to the top of the thin diaphragm. With the gauge pressure sensor, the back side is vented to atmosphere. This could […]
Differential pressure transmitters are quickly configurable, require no calibration
Superior Sensor Technology today announced the HS Series, an advanced family of differential pressure transmitter (DPT) subsystems that offer engineers a flexible, accurate and easily configurable DPT design solution for HVAC and industrial air handling systems. The HS Series is a DPT subsystem which includes the already popular performance features of the HV Series with additional […]
What is the difference between a pressure sensor and a load cell?
A load cell is a type of force sensor and it has a direct relationship to pressure, since: pressure = force/area Eq. 1 The load cell’s electrical output is proportional to the mechanical force applied to it. The force can be hydraulic or pneumatic and the transducer is normally based on strain gauges. Other types […]
