Connection heads
Forms A to XI-DSNW — aluminium, plastic and ATEX, with cable entry M20, NPT or PG and process connection M24, G ½" or tube Ø.
The connection head holds the terminal block or the transmitter and closes the measuring point off to the outside. Its two dimensions decide whether it fits: the cable entry towards the cable and the process connection towards the thermowell or the sensor. Both are given for every version in the finder.
We supply the heads on their own, with a matching terminal block or complete on the finished thermometer. Programmed transmitters we fit directly on request.
