PRESSURE Product Data Sheet 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. SPECIFICATION Pressure Range Excitation Output Span: Zero: Non Linearity, Hysteresis & Repeatability (NLH) Operating Temp Range Safe Over-range Burst Pressure Insulation Resistance Loading Driving Environmental Protection Electrical Connections 5,10, 20, & 50 bar SG and G 10-32Vdc unregulated 16mA +1% of span at pressure 4mA +1% of span at zero pressure <+1% of span (best fit straight line) -25oC to +100oC 1.5 times rated range 3 times rated range minimum >500M Ω at 500Vdc, over the operable temperature range 1k Ω @ 28Vdc supply IP68 Cable It offers a two wire, 4-20mA output proportional to fluid pressure with other outputs available as options.
