Kistler Model 4065A Piezoresistive High Pressure Sensor With Amplifier
High pressure sensor with rugged diaphragm for measuring
on hydraulic systems, (e.g. fuel injection systems in internal combustion engines), and gas pressure measurements. Suitable
for static and dynamic pressures. Its small dimensions allow its use with a clamp adapter on the injection pipe. High natural
frequency. This is one of the smallest high-pressure sensors on the market for static and dynamic measurement. It is
supplied together with an adjusted amplifier Type 4618A.
The pressure to be measured acts through a rugged diaphragm on an arrangement of piezoresistive 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 4065 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 on diesel engines or measurements on hydraulic systems.
• Measuring ranges up to 1000 bar
• Measures static and dynamic pressures
• High natural frequency
