Sensit P6420-57 Abrasive Material
Pressure Transmitter
The Sensit P6420-57 is a pressure transducer having a
two wire, 4-20mA output. It is available in standard
ranges from 5 bar to 50 bar, or may be scaled to
customer requirements.
DESCRIPTION
The P6420-57 pressure transducer 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 been designed primarily for use with
concrete slurry and other abrasive fluids and has a
cavity free, flush sensing diaphragm covered by a
flexible polypropylene shield.
