![]() Force washers can be used on both bolts and screws, so the inside diameter of force washers usually corresponds to the outside diameter of metric threads. These sensors can be to be calibrated o already calibrated. ![]() to use one sensor instead of two or more sensors with different measuring ranges, thus ensuring the most suitable full scale, simply by using the charge amplifier. fractioning can be avoided It is possible to avoid fractioning, i.e. A further significant feature of piezoelectric technology is the possibility of calibrating and programming different measuring ranges due to the high accuracy. They are maintenance-free and can be installed in locations that are difficult to access. All transducers are made of stainless steel and are suitable for use in harsh industrial environments with stringent operational requirements. Further advantages of these sensors are: a high operating temperature range high operating temperature range (-196☌ +700☌) and a easy signal summation for sensors mounted in parallel. This results in a high resonance frequency which, in principle, is very favourable for dynamic or quasi-static applications. Given their principle of operation, these sensors have a drift of 1N/minute while the measurement chain is in operation they show very small deflections when force is applied, thus offering high stiffness. The charge is proportional to the force applied. When force is applied, an electrical charge is generated that can be measured by a charge amplifier. I piezoelectric sensors consist of two crystal disks with a foil electrode between them.
