A pressure sensor is a device for pressure measurement of gases or liquids. The pressure is an expression of the force required to stop a fluid from expanding and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer, it generates a signal as a function of the pressure imposed. Here is a huge collection of Load / Force Sensor.

Load cells (Weighing cell) are available in the range from 1kg to 20kg. Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude.
