nnPRESSURE M6420-92 Flush Mounted Transmitter nn

The M6420-92 is ideal for applications where thesensing element has to be in direct contact with the
media.This enables measurement of medias that
contain particles or are liable to congeal.

Pressure Ranges 1,2,3,5,10,20 & 50 bar gauge or absolute.Other ranges available Excitation 10-32Vdc unregulated Output Span 16mA 1% >

The M6420-92 pressure transmitter is based on a four
active arm strain gauge bridge fused to a high purity
ceramic diaphragm,offering high natural output
coupled with superb chemical and corrosion
resistance.It has a two wire,4-20mA output
proportional to pressure and is fully CE compliant.
The sensing element and its associated electronics
are housed in a rugged stainless steel case.It has a
M24 x 2 threaded pressure fitting and a flush
mounted sensor,sealed via an O-ring.
