Kistler High-Pressure Pressure Sensor With Amplifier Model 4067
|
This is one of the smallest sensors on the market for static measurement. It is supplied together with amplifier Type 4618A Option with Type 4620A2 (total error < 0.5%, fg > 300 Hz) upon request. The pressure to be measured acts through a rugged diaphragm on an arrangement of piezoresistive rods. The pressure changes the values of the resistance's diffused into the rods. These resistance's are arranged in a Wheatstone bridge. The pressure sensor itself is not temperature compensated. The amplifier Type 4618 provides temperature compensation, linearization of the pressure signal and contains a stabilized power supply. For this reason, the sensor must always be operated with the amplifier adjusted to it. Amplifier Type 4618 additionally contains two adjustable limit switches with optocouplers. A version with simultaneous temperature measurement is available as an option. Sensor Type 4067 is used appropriately wherever high pressures with a static component have to be measured in confined spaces. Examples are the fine tuning of injection systems and diesel engines or measurements on hydraulic systems. |
