PRESSURE Product Data Sheet 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. 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 IP67 Terminal Head (IP67) It offers a two wire, 4-20mA output proportional to fluid pressure with other outputs available as options. The sensing element and its associated electronics are housed in a rugged stainless steel case. Superb chemical and corrosion resistance 4-20mA, two wire operation (option 5-21mA) Unrivalled abrasion resistance Wide temperature range High electrical isolation Rugged construction Excellent long term stability Concrete pumping & other abrasive applications Gypsum Brick Dust Clay
