Mechanical Sensor

Sensors for measuring various mechanical parameters are included under this category.

Mechanical parameters being measured by numerous types of mechanical sensors are flow, pressure, acceleration, vibration,
movements, torque, axial load, temperature etc. for machinery and other industrial applications. Sensors and actuators are a major part of mechanical sensors There are analogue and digital type of sensors available. Transmitters, Sensors and actuators are often part of a complete solution under this category.

Pressure sensors are one of the most commonly used application under mechanical sensors. Pressure to be monitored include liquid pressure, the mechanical pressure being applied to machine components, pneumatic pressure in hydraulic machinery, barometric pressure, vacuum pressure etc. and are commonly associated with pressure transmitters which are for transmission of the sensor signals to other devices. Pressure gauges are generally analogue devices for displaying the pressure measurement. Nowadays the term pressure gauge is also used for digital displays.

Pressure transmitters are used for process control and automation which will require monitoring, control and coordination between various elements. All such transmitters convert the measured signals into a proportionate electrical voltage and current signals. Many of the models of pressure transmitters have a locally mounted digital display along with the pressure sensor so that the readings are available locally and also is transmitted for centralised monitoring and control.

Differential pressure sensors are used for air, gas etc. to monitor pressure difference between two areas. A typical usage of the same is to monitor pressure difference between special care units in hospitals, critical manufacturing areas etc.
