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.
The most common torque sensor measurement principle uses bonded strain gauge technology, where the strain gauges are bonded to a suitably designed shaft.
How a Load Cell WorksThe conversion is achieved by the physical deformation of strain gauges, which are bonded onto the load cell structure. The strain gauges are connected into a Wheatstone Bridge circuit with four strain gauges (full bridge), two gauges (half bridge) or one gauge (quarter bridge).
