Series 3L...10L is a new range of transducers that benefit from smaller capsule dimensions and crevice free diaphragms. Keller has developed a new technique for laser welding very thin stainless steel media isolation diaphragms. The smaller crevice free transducers still retain all the traditional performance, stability, and quality, for which Keller is renowned.
Each transducer is supplied with a calibration sheet indicating sensitivity, linearity, zero offset, temperature errors and the compensation resistors to substantially reduce zero offset and zero temperature errors.
With the laser welded technology, transducers diameters as low as 9.5 mm can be realized. Diameter is, to some extent, dependent upon the pressure range measured; low pressures require larger diameters and higher pressures can be achieved with smaller diameters. This is due to the expansion of the oil under temperature that creates an internal pressure due to the resistance of the diaphragm. The smaller the diameter, the higher the internal pressure and the more difficult is the zero compensation.
