SEN-3291 Pressure Transducer

Brand: KOBOLD Instruments, Inc.

The Heavy Duty Industrial pressure transducers are leaders among pressure transducers. The flush type diaphragm allows the use with aggressive, viscous or crystallizing process fluids. This type of sealing permits cleaning of the process connections without residues.

With an accuracy of 0.1% (0.05% optional) use in testing and calibration is given. By a programmatic compensation temperature of 10° to 60° C, the temperature-induced error is practically zero.

As measuring element, a piezo resistive sensor is used. Case and wetted parts are stainless steel. Therefore the are extremely resistant against aggressive media and fulfill the most demanding requirements.

The pressure connection and measuring element are welded together, making the measuring system particularly resistant to mechanical shock or vibration. Optional software is available to adjust zero and span in difficult applications like measurement of the hydrostatic column.
