PRESSURE Product Data Sheet Sensit OEM 4-20mA Output Pressure Transmitter The M6420-50 is a two wire, 4-20mA pressure transmitter and is available in standard ranges from 0.5 bar to 600 bar, or may be scaled to customer requirements. All ranges are available in gauge or absolute format. FEATURES Rugged construction / small size 4-20mA output Excellent linearity DESCRIPTION The M6420-50 pressure transmitter is based on a four active arm strain gauge bridge fused to a high purity alumina ceramic diaphragm, offering high natural output coupled with superb chemical and corrosion resistance. This is housed within a stainless steel case with integral electronics and is supplied with a plug and socket electrical connection. Pressure connection is a G1/4 male thread as standard. Other threads are available on request. Cost effective High electrical isolation Excellent long term stability SPECIFICATION Pressure Range Excitation Output - Span Output - Zero Non Linearity, Hysteresis & Repeatability (NLH) Operating Temp Range Thermal Zero Shift Thermal Span Shift Safe Over-range Pressure Burst Pressure Output Resistance Load Driving Environmental Rating Insulation/Isolation Resistance Available in ranges between 0.5 bar and 600 bar gauge or absolute 10-32Vdc 16mA ±1% of span at zero pressure 4mA ±1% span ±0.25% of span (best fit straight line) -25ºC to 80ºC <±0.08% of span/ºC typical <-0.04% reading/ºC typical 1.5 x rated range minimum 3 x rated range minimum >10M Ω 1k Ω @ 30Vdc supply IP65 >500M Ω @ 50Vdc
