Keller Swiss-Built Series 23S-25S High accuracy compact pressure transmitter

This transmitter is well suited for use in industrial applications that require good accuracy and high stability. It is designed especially for safety critical applications where media compatibility is paramount. The Series 23S / 25S features a fully welded pressure port construction, no internal O-Rings or seals are used up to 600 bar. The wetted materials are a 316L stainless steel housing and a brazed diaphragm.!¤ Series 23    Male pressure port G1/4!  Accuracy 0,25 %FS (best straight line), optional 0,1 %FS!¤ Series 25   G1/2!± pressure port with lush diaphrag.  Accuracy 0,25 %FS (best straight line), optional 0,1 %FS Series 23 S. A Comprehensive Range Absolute, barometric, gauge (positive and negative pressures). 16 nominal pressure ranges. Current or voltage output. Flexibility A modular concept is used, with fast and economical production achieved by using off-the-shelf Series 7 S and 9 S capsules and Series 6 S sensors.Numerous options and variations are available to meet customers!ˉ speciic requirements:
Pressure ranges, pressure ports, signal outputs, electrical connectors, etc.Quality Each transmitter is subjected to severe test- and calibration procedures. Transmitters are manufactured and tested according to ISO 9001:2000.
