Pressure Measurement & Control


Keller's precise pressure transmitters

September 2012 Pressure Measurement & Control

Keller offers its highly precise range of transmitters – series 33x and 35x. In the 33x range, the highly precise 0,01%FS is available as an option (the standard Series 33x has an accuracy of 0,05%FS). The series is based on the stable, floating piezoresisitive transducer and the newly developed Xemics micro-processor with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated. With the Read30 software and the Keller cable K-107, the calculated pressure can be displayed on a laptop or PC. The software also allows the recording of pressure signals and graphic display. Applications include:

* Plant engineering – vapour pressure measurement in closed milk tanks.

* Automotive – transmission testing of engines on test benches.

* Mining – hydraulic pressure monitoring of mining applications.

* Electronic – monitoring of SF6 switches for gas density calculations.

* Aviation – monitors cabin pressure (oxygen masks) and airflow on plane profiles.

* Machine building – monitors and controls hydraulic pressure of press brakes.

* Test engineering – pressure monitoring of test engines for Formula 1 cars.

The Series 35x, a high accuracy flush diaphragm digital and analogue output transmitter, is used in medical technology for the control and measurement of protein filtrations and in the chemical industry for pressure monitoring in autoclaves of bioreactors during sterilisation.
