The main advantages of piezoelectric sensors are robustness and low power.
The sensing elements are made of rigid materials, which can be natural crystals such as quartz or specially formulated ceramics. These require only a very small deformation to generate an output, so there are effectively no moving parts.
The capacitive element is mechanically simple and robust.
Capacitive sensors are able to operate over a wide temperature range and are very tolerant of short-term overpressure conditions.
They can be used to measure a wide range of pressure from vacuum (2.5 mbar or 250 Pa) to high pressures up to around 10,000 psi (70 MPa). They’re ideal for both lower-pressure applications and reasonably harsh environments.
Advantages and disadvantages of Piezoresistive strain gauge sensors Piezoresistive strain gauge sensorsThese are the earliest and most widely used type of pressure sensor.The simple construction means low cost and durability. The sensors are robust with good resistance to shock, vibration, and dynamic pressure changes.
Industrial pressure sensors also referred to as pressure transducers, pressure transmitters, pressure indicators and pressure switches, normally have a diaphragm type design that uses strain gauges, which are either bonded to or diffused into it, with the strain gauges acting as resistive elements.
Hydrostatic submersible level sensors, designed to measure the level or depth of liquids. They can be fully submerged in the media being measured with protection class IP68.
Terms of pressure sensor, pressure transducer and pressure transmitter are somewhat interchangeable in the industrial world. Pressure sensors can be described with a 4-20mA output signal and pressure transducers with a millivolt signal.
Inclinometers & Tilt Sensors & Clinometers An inclinometer, tilt sensor or Clinometers is an instrument used for measuring angles of slope (or tilt), elevation, or depression of an object with respect to gravity's direction.
Types of Pressure SensorsPressure sensors can be classified in terms of the pressure range they are measuring, operating temperature range, or the type of pressure they are measuring. In terms of pressure types, pressure sensors can be divided into several main categories:① Absolute Pressure Sensor
PT100 Temperature Sensor (RTD)Pt100 is a sensor used to measure temperature. It is one type of sensor which falls into a group called Resistance Temperature Detectors or RTD’s.
Reaction Torque Transducer PrinciplesA reaction transducer has two mounting flanges. One face is fixed to ground or a rigid structural member and the other to the rotating or rotary element. Rotation generates shear forces between the flanges.
