Sensit P6420-61 Abrasive Material
Pressure Transmitter
The P6420-61 is a pressure transducer having a two
wire, 4-20mA output. It is available in standard ranges
from 5bar to 50bar, or may be scaled to customer
requirements.

DESCRIPTION
The P6420-61 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.
